All +middlewares will populate the `req.body` property with the parsed body when +the `Content-Type` request header matches the `type` option, or an empty +object (`{}`) if there was no body to parse, the `Content-Type` was not matched, +or an error occurred. + +The various errors returned by this module are described in the +[errors section](#errors). + +### bodyParser.json([options]) + +Returns middleware that only parses `json` and only looks at requests where +the `Content-Type` header matches the `type` option. This parser accepts any +Unicode encoding of the body and supports automatic inflation of `gzip` and +`deflate` encodings. + +A new `body` object containing the parsed data is populated on the `request` +object after the middleware (i.e. `req.body`). + +#### Options + +The `json` function takes an optional `options` object that may contain any of +the following keys: + +##### inflate + +When set to `true`, then deflated (compressed) bodies will be inflated; when +`false`, deflated bodies are rejected. Defaults to `true`. + +##### limit + +Controls the maximum request body size. If this is a number, then the value +specifies the number of bytes; if it is a string, the value is passed to the +[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults +to `'100kb'`. + +##### reviver + +The `reviver` option is passed directly to `JSON.parse` as the second +argument. You can find more information on this argument +[in the MDN documentation about JSON.parse](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Example.3A_Using_the_reviver_parameter). + +##### strict + +When set to `true`, will only accept arrays and objects; when `false` will +accept anything `JSON.parse` accepts. Defaults to `true`. + +##### type + +The `type` option is used to determine what media type the middleware will +parse. This option can be a function or a string. If a string, `type` option +is passed directly to the [type-is](https://www.npmjs.org/package/type-is#readme) +library and this can be an extension name (like `json`), a mime type (like +`application/json`), or a mime type with a wildcard (like `*/*` or `*/json`). +If a function, the `type` option is called as `fn(req)` and the request is +parsed if it returns a truthy value. Defaults to `application/json`. + +##### verify + +The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, +where `buf` is a `Buffer` of the raw request body and `encoding` is the +encoding of the request. The parsing can be aborted by throwing an error. + +### bodyParser.raw([options]) + +Returns middleware that parses all bodies as a `Buffer` and only looks at +requests where the `Content-Type` header matches the `type` option. This +parser supports automatic inflation of `gzip` and `deflate` encodings. + +A new `body` object containing the parsed data is populated on the `request` +object after the middleware (i.e. `req.body`). This will be a `Buffer` object +of the body. + +#### Options + +The `raw` function takes an optional `options` object that may contain any of +the following keys: + +##### inflate + +When set to `true`, then deflated (compressed) bodies will be inflated; when +`false`, deflated bodies are rejected.

If a string, `type` option +is passed directly to the [type-is](https://www.npmjs.org/package/type-is#readme) +library and this can be an extension name (like `bin`), a mime type (like +`application/octet-stream`), or a mime type with a wildcard (like `*/*` or +`application/*`). If a function, the `type` option is called as `fn(req)` +and the request is parsed if it returns a truthy value.

The parsing can be aborted by throwing an error. + +### bodyParser.text([options]) + +Returns middleware that parses all bodies as a string and only looks at +requests where the `Content-Type` header matches the `type` option. This +parser supports automatic inflation of `gzip` and `deflate` encodings. + +A new `body` string containing the parsed data is populated on the `request` +object after the middleware (i.e. `req.body`). This will be a string of the +body. + +#### Options + +The `text` function takes an optional `options` object that may contain any of +the following keys: + +##### defaultCharset + +Specify the default character set for the text content if the charset is not +specified in the `Content-Type` header of the request. Defaults to `utf-8`. + +##### inflate + +When set to `true`, then deflated (compressed) bodies will be inflated; when +`false`, deflated bodies are rejected. Defaults to `true`. + +##### limit + +Controls the maximum request body size. If this is a number, then the value +specifies the number of bytes; if it is a string, the value is passed to the +[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults +to `'100kb'`. + +##### type + +The `type` option is used to determine what media type the middleware will +parse. This option can be a function or a string. If a string, `type` option +is passed directly to the [type-is](https://www.npmjs.org/package/type-is#readme) +library and this can be an extension name (like `txt`), a mime type (like +`text/plain`), or a mime type with a wildcard (like `*/*` or `text/*`). +If a function, the `type` option is called as `fn(req)` and the request is +parsed if it returns a truthy value. Defaults to `text/plain`. + +##### verify + +The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, +where `buf` is a `Buffer` of the raw request body and `encoding` is the +encoding of the request. The parsing can be aborted by throwing an error. + +### bodyParser.urlencoded([options]) + +Returns middleware that only parses `urlencoded` bodies and only looks at +requests where the `Content-Type` header matches the `type` option. This +parser accepts only UTF-8 encoding of the body and supports automatic +inflation of `gzip` and `deflate` encodings. + +A new `body` object containing the parsed data is populated on the `request` +object after the middleware (i.e. `req.body`). This object will contain +key-value pairs, where the value can be a string or array (when `extended` is +`false`), or any type (when `extended` is `true`). + +#### Options + +The `urlencoded` function takes an optional `options` object that may contain +any of the following keys: + +##### extended + +The `extended` option allows to choose between parsing the URL-encoded data +with the `querystring` library (when `false`) or the `qs` library (when +`true`). The "extended" syntax allows for rich objects and arrays to be +encoded into the URL-encoded format, allowing for a JSON-like experience +with URL-encoded. For more information, please +[see the qs library](https://www.npmjs.org/package/qs#readme). + +Defaults to `true`, but using the default has been deprecated. Please +research into the difference between `qs` and `querystring` and choose the +appropriate setting. + +##### inflate + +When set to `true`, then deflated (compressed) bodies will be inflated; when +`false`, deflated bodies are rejected. Defaults to `true`. + +##### limit + +Controls the maximum request body size. If this is a number, then the value +specifies the number of bytes; if it is a string, the value is passed to the +[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults +to `'100kb'`. + +##### parameterLimit + +The `parameterLimit` option controls the maximum number of parameters that +are allowed in the URL-encoded data. If a request contains more parameters +than this value, a 413 will be returned to the client. Defaults to `1000`. + +##### type + +The `type` option is used to determine what media type the middleware will +parse. This option can be a function or a string. If a string, `type` option +is passed directly to the [type-is](https://www.npmjs.org/package/type-is#readme) +library and this can be an extension name (like `urlencoded`), a mime type (like +`application/x-www-form-urlencoded`), or a mime type with a wildcard (like +`*/x-www-form-urlencoded`). If a function, the `type` option is called as +`fn(req)` and the request is parsed if it returns a truthy value. Defaults +to `application/x-www-form-urlencoded`. + +##### verify + +The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, +where `buf` is a `Buffer` of the raw request body and `encoding` is the +encoding of the request. The parsing can be aborted by throwing an error. + +## Errors + +The middlewares provided by this module create errors depending on the error +condition during parsing. The errors will typically have a `status`/`statusCode` +property that contains the suggested HTTP response code, an `expose` property +to determine if the `message` property should be displayed to the client, a +`type` property to determine the type of error without matching against the +`message`, and a `body` property containing the read body, if available. + +The following are the common errors emitted, though any error can come through +for various reasons. + +### content encoding unsupported + +This error will occur when the request had a `Content-Encoding` header that +contained an encoding but the "inflation" option was set to `false`. The +`status` property is set to `415`, the `type` property is set to +`'encoding.unsupported'`, and the `charset` property will be set to the +encoding that is unsupported. + +### request aborted + +This error will occur when the request is aborted by the client before reading +the body has finished. The `received` property will be set to the number of +bytes received before the request was aborted and the `expected` property is +set to the number of expected bytes. The `status` property is set to `400` +and `type` property is set to `'request.aborted'`. + +### request entity too large + +This error will occur when the request body's size is larger than the "limit" +option. The `limit` property will be set to the byte limit and the `length` +property will be set to the request body's length. The `status` property is +set to `413` and the `type` property is set to `'entity.too.large'`. + +### request size did not match content length + +This error will occur when the request's length did not match the length from +the `Content-Length` header. This typically occurs when the request is malformed, +typically when the `Content-Length` header was calculated based on characters +instead of bytes. The `status` property is set to `400` and the `type` property +is set to `'request.size.invalid'`. + +### stream encoding should not be set + +This error will occur when something called the `req.setEncoding` method prior +to this middleware. This module operates directly on bytes only and you cannot +call `req.setEncoding` when using this module. The `status` property is set to +`500` and the `type` property is set to `'stream.encoding.set'`. + +### too many parameters + +This error will occur when the content of the request exceeds the configured +`parameterLimit` for the `urlencoded` parser. The `status` property is set to +`413` and the `type` property is set to `'parameters.too.many'`. + +### unsupported charset "BOGUS" + +This error will occur when the request had a charset parameter in the +`Content-Type` header, but the `iconv-lite` module does not support it OR the +parser does not support it. The charset is contained in the message as well +as in the `charset` property. The `status` property is set to `415`, the +`type` property is set to `'charset.unsupported'`, and the `charset` property +is set to the charset that is unsupported. + +### unsupported content encoding "bogus" + +This error will occur when the request had a `Content-Encoding` header that +contained an unsupported encoding. The encoding is contained in the message +as well as in the `encoding` property. The `status` property is set to `415`, +the `type` property is set to `'encoding.unsupported'`, and the `encoding` +property is set to the encoding that is unsupported. + +## Examples + +### Express/Connect top-level generic + +This example demonstrates adding a generic JSON and URL-encoded parser as a +top-level middleware, which will parse the bodies of all incoming requests. +This is the simplest setup. + +```js +var express = require('express') +var bodyParser = require('body-parser') + +var app = express() + +// parse application/x-www-form-urlencoded +app.use(bodyParser.urlencoded({ extended: false })) + +// parse application/json +app.use(bodyParser.json()) + +app.use(function (req, res) { + res.setHeader('Content-Type', 'text/plain') + res.write('you posted:\n') + res.end(JSON.stringify(req.body, null, 2)) +}) +``` + +### Express route-specific + +This example demonstrates adding body parsers specifically to the routes that +need them. In general, this is the most recommended way to use body-parser with +Express. + +```js +var express = require('express') +var bodyParser = require('body-parser') + +var app = express() + +// create application/json parser +var jsonParser = bodyParser.json() + +// create application/x-www-form-urlencoded parser +var urlencodedParser = bodyParser.urlencoded({ extended: false }) + +// POST /login gets urlencoded bodies +app.post('/login', urlencodedParser, function (req, res) { + if (!req.body) return res.sendStatus(400) + res.send('welcome, ' + req.body.username) +}) + +// POST /api/users gets JSON bodies +app.post('/api/users', jsonParser, function (req, res) { + if (!req.body) return res.sendStatus(400) + // create user in req.body +}) +``` + +### Change accepted type for parsers + +All the parsers accept a `type` option which allows you to change the +`Content-Type` that the middleware will parse. + +```js +var express = require('express') +var bodyParser = require('body-parser') + +var app = express() + +// parse various different custom JSON types as JSON +app.use(bodyParser.json({ type: 'application/*+json' })) + +// parse some custom thing into a Buffer +app.use(bodyParser.raw({ type: 'application/vnd.custom-type' })) + +// parse an HTML body into a string +app.use(bodyParser.text({ type: 'text/html' })) +``` + +## License + +[MIT](LICENSE) +

require('cookie'); +``` + +### cookie.parse(str, options) + +Parse an HTTP `Cookie` header string and returning an object of all cookie name-value pairs. +The `str` argument is the string representing a `Cookie` header value and `options` is an +optional object containing additional parsing options. + +```js +var cookies = cookie.parse('foo=bar; equation=E%3Dmc%5E2'); +// { foo: 'bar', equation: 'E=mc^2' } +``` + +#### Options + +`cookie.parse` accepts these properties in the options object. + +##### decode + +Specifies a function that will be used to decode a cookie's value. Since the value of a cookie +has a limited character set (and must be a simple string), this function can be used to decode +a previously-encoded cookie value into a JavaScript string or other object. + +The default function is the global `decodeURIComponent`, which will decode any URL-encoded +sequences into their byte representations. + +**note** if an error is thrown from this function, the original, non-decoded cookie value will +be returned as the cookie's value. + +### cookie.serialize(name, value, options) + +Serialize a cookie name-value pair into a `Set-Cookie` header string. The `name` argument is the +name for the cookie, the `value` argument is the value to set the cookie to, and the `options` +argument is an optional object containing additional serialization options. + +```js +var setCookie = cookie.serialize('foo', 'bar'); +// foo=bar +``` + +#### Options + +`cookie.serialize` accepts these properties in the options object. + +##### domain + +Specifies the value for the [`Domain` `Set-Cookie` attribute][rfc-6266-5.2.3]. By default, no +domain is set, and most clients will consider the cookie to apply to only the current domain. + +##### encode + +Specifies a function that will be used to encode a cookie's value. Since value of a cookie +has a limited character set (and must be a simple string), this function can be used to encode +a value into a string suited for a cookie's value. + +The default function is the global `ecodeURIComponent`, which will encode a JavaScript string +into UTF-8 byte sequences and then URL-encode any that fall outside of the cookie range. + +##### expires + +Specifies the `Date` object to be the value for the [`Expires` `Set-Cookie` attribute][rfc-6266-5.2.1]. +By default, no expiration is set, and most clients will consider this a "non-persistent cookie" and +will delete it on a condition like exiting a web browser application. + +**note** the [cookie storage model specification][rfc-6266-5.3] states that if both `expires` and +`magAge` are set, then `maxAge` takes precedence, but it is possiblke not all clients by obey this, +so if both are set, they should point to the same date and time. + +##### httpOnly + +Specifies the `boolean` value for the [`HttpOnly` `Set-Cookie` attribute][rfc-6266-5.2.6]. When truthy, +the `HttpOnly` attribute is set, otherwise it is not. By default, the `HttpOnly` attribute is not set. + +**note** be careful when setting this to `true`, as compliant clients will not allow client-side +JavaScript to see the cookie in `document.cookie`. + +##### maxAge + +Specifies the `number` (in seconds) to be the value for the [`Max-Age` `Set-Cookie` attribute][rfc-6266-5.2.2]. +The given number will be converted to an integer by rounding down. By default, no maximum age is set. + +**note** the [cookie storage model specification][rfc-6266-5.3] states that if both `expires` and +`magAge` are set, then `maxAge` takes precedence, but it is possiblke not all clients by obey this, +so if both are set, they should point to the same date and time. + +##### path + +Specifies the value for the [`Path` `Set-Cookie` attribute][rfc-6266-5.2.4]. By default, the path +is considered the ["default path"][rfc-6266-5.1.4]. By default, no maximum age is set, and most +clients will consider this a "non-persistent cookie" and will delete it on a condition like exiting +a web browser application. + +##### sameSite + +Specifies the `boolean` or `string` to be the value for the [`SameSite` `Set-Cookie` attribute][draft-west-first-party-cookies-07]. + + - `true` will set the `SameSite` attribute to `Strict` for strict same site enforcement. + - `false` will not set the `SameSite` attribute. + - `'lax'` will set the `SameSite` attribute to `Lax` for lax same site enforcement. + - `'strict'` will set the `SameSite` attribute to `Strict` for strict same site enforcement. + +More information about the different enforcement levels can be found in the specification +https://tools.ietf.org/html/draft-west-first-party-cookies-07#section-4.1.1 + +**note** This is an attribute that has not yet been fully standardized, and may change in the future. +This also means many clients may ignore this attribute until they understand it. + +##### secure + +Specifies the `boolean` value for the [`Secure` `Set-Cookie` attribute][rfc-6266-5.2.5]. When truthy, +the `Secure` attribute is set, otherwise it is not. By default, the `Secure` attribute is not set. + +**note** be careful when setting this to `true`, as compliant clients will not send the cookie back to +the server in the future if the browser does not have an HTTPS connection. + +## Example + +The following example uses this module in conjunction with the Node.js core HTTP server +to prompt a user for their name and display it back on future visits. + +```js +var cookie = require('cookie'); +var escapeHtml = require('escape-html'); +var http = require('http'); +var url = require('url'); + +function onRequest(req, res) { + // Parse the query string + var query = url.parse(req.url, true, true).query; + + if (query && query.name) { + // Set a new cookie with the name + res.setHeader('Set-Cookie', cookie.serialize('name', String(query.name), { + httpOnly: true, + maxAge: 60 * 60 * 24 * 7 // 1 week + })); + + // Redirect back after setting cookie + res.statusCode = 302; + res.setHeader('Location', req.headers.referer || '/'); + res.end(); + return; + } + + // Parse the cookies on the request + var cookies = cookie.parse(req.headers.cookie || ''); + + // Get the visitor name set in the cookie + var name = cookies.name; + + res.setHeader('Content-Type', 'text/html; charset=UTF-8'); + + if (name) { + res.write('

This will allow you to toggle the debug output for different parts of your module as well as the module as a whole. + +Example _app.js_: + +```js +var debug = require('debug')('http') + , http = require('http') + , name = 'My App'; + +// fake app + +debug('booting %s', name); + +http.createServer(function(req, res){ + debug(req.method + ' ' + req.url); + res.end('hello\n'); +}).listen(3000, function(){ + debug('listening'); +}); + +// fake worker of some kind + +require('./worker'); +``` + +Example _worker.js_: + +```js +var debug = require('debug')('worker'); + +setInterval(function(){ + debug('doing some work'); +}, 1000); +``` + + The __DEBUG__ environment variable is then used to enable these based on space or comma-delimited names. Here are some examples: + + ![debug http and worker](http://f.cl.ly/items/18471z1H402O24072r1J/Screenshot.png) + + ![debug worker](http://f.cl.ly/items/1X413v1a3M0d3C2c1E0i/Screenshot.png) + +#### Windows note + + On Windows the environment variable is set using the `set` command. + + ```cmd + set DEBUG=*,-not_this + ``` + + Note that PowerShell uses different syntax to set environment variables. + + ```cmd + $env:DEBUG = "*,-not_this" + ``` + +Then, run the program to be debugged as usual. + +## Millisecond diff + + When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls. + + ![](http://f.cl.ly/items/2i3h1d3t121M2Z1A3Q0N/Screenshot.png) + + When stdout is not a TTY, `Date#toUTCString()` is used, making it more useful for logging the debug information as shown below: + + ![](http://f.cl.ly/items/112H3i0e0o0P0a2Q2r11/Screenshot.png) + +## Conventions + + If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". + +## Wildcards + + The `*` character may be used as a wildcard. Suppose for example your library has debuggers named "connect:bodyParser", "connect:compress", "connect:session", instead of listing all three with `DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do `DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`. + + You can also exclude specific debuggers by prefixing them with a "-" character. For example, `DEBUG=*,-connect:*` would include all debuggers except those starting with "connect:". + +## Environment Variables + + When running through Node.js, you can set a few environment variables that will + change the behavior of the debug logging: + +| Name | Purpose | +|-----------|-------------------------------------------------| +| `DEBUG` | Enables/disables specific debugging namespaces. | +| `DEBUG_COLORS`| Whether or not to use colors in the debug output. | +| `DEBUG_DEPTH` | Object inspection depth. | +| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. | + + + __Note:__ The environment variables beginning with `DEBUG_` end up being + converted into an Options object that gets used with `%o`/`%O` formatters. + See the Node.js documentation for + [`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options) + for the complete list. + +## Formatters + + + Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. Below are the officially supported formatters: + +| Formatter | Representation | +|-----------|----------------| +| `%O` | Pretty-print an Object on multiple lines. | +| `%o` | Pretty-print an Object all on a single line. | +| `%s` | String. | +| `%d` | Number (both integer and float). | +| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. | +| `%%` | Single percent sign ('%'). This does not consume an argument. | + +### Custom formatters + + You can add custom formatters by extending the `debug.formatters` object. For example, if you wanted to add support for rendering a Buffer as hex with `%h`, you could do something like: + +```js +const createDebug = require('debug') +createDebug.formatters.h = (v) => { + return v.toString('hex') +} + +// …elsewhere +const debug = createDebug('foo') +debug('this is hex: %h', new Buffer('hello world')) +// foo this is hex: 68656c6c6f20776f726c6421 +0ms +``` + +## Browser support + You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify), + or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest), + if you don't want to build it yourself. + + Debug's enable state is currently persisted by `localStorage`. + Consider the situation shown below where you have `worker:a` and `worker:b`, + and wish to debug both. You can enable this using `localStorage.debug`: + +```js +localStorage.debug = 'worker:*' +``` + +And then refresh the page. + +```js +a = debug('worker:a'); +b = debug('worker:b'); + +setInterval(function(){ + a('doing some work'); +}, 1000); + +setInterval(function(){ + b('doing some work'); +}, 1200); +``` + +#### Web Inspector Colors + + Colors are also enabled on "Web Inspectors" that understand the `%c` formatting + option. These are WebKit web inspectors, Firefox ([since version + 31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/)) + and the Firebug plugin for Firefox (any version). + + Colored output looks something like: + + ![](https://cloud.githubusercontent.com/assets/71256/3139768/b98c5fd8-e8ef-11e3-862a-f7253b6f47c6.png) + + +## Output streams + + By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method: + +Example _stdout.js_: + +```js +var debug = require('debug'); +var error = debug('app:error'); + +// by default stderr is used +error('goes to stderr!'); + +var log = debug('app:log'); +// set this namespace to log via console.log +log.log = console.log.bind(console); // don't forget to bind to console! +log('goes to stdout'); +error('still goes to stderr!'); + +// set all output to go via console.info +// overrides all per-namespace log settings +debug.log = console.info.bind(console); +error('now goes to stdout via console.info'); +log('still goes to stdout, but via console.info now'); +``` + + +## Authors + + - TJ Holowaychuk + - Nathan Rajlich + - Andrew Rhyne + +## Backers + +Support us with a monthly donation and help us continue our activities.

We recommend that you set + `graphiql` to `true` when your app is in development, because it's + quite useful. You may or may not want it in production. + + * **`rootValue`**: A value to pass as the `rootValue` to the `graphql()` + function from [`GraphQL.js/src/execute.js`](https://github.com/graphql/graphql-js/blob/master/src/execution/execute.js#L121). + + * **`context`**: A value to pass as the `context` to the `graphql()` + function from [`GraphQL.js/src/execute.js`](https://github.com/graphql/graphql-js/blob/master/src/execution/execute.js#L122). If `context` is not provided, the + `request` object is passed as the context. + + * **`pretty`**: If `true`, any JSON response will be pretty-printed. + + * **`formatError`**: An optional function which will be used to format any + errors produced by fulfilling a GraphQL operation. If no function is + provided, GraphQL's default spec-compliant [`formatError`][] function will be used. + + * **`extensions`**: An optional function for adding additional metadata to the + GraphQL response as a key-value object. The result will be added to + `"extensions"` field in the resulting JSON. This is often a useful place to + add development time metadata such as the runtime of a query or the amount + of resources consumed. This may be an async function. The function is + given one object as an argument: `{ document, variables, operationName, result }`. + + * **`validationRules`**: Optional additional validation rules queries must + satisfy in addition to those defined by the GraphQL spec. + +In addition to an object defining each option, options can also be provided as +a function (or async function) which returns this options object. This function +is provided the arguments `(request, response, graphQLParams)` and is called +after the request has been parsed. + +The `graphQLParams` is provided as the object `{ query, variables, operationName, raw }`. + +```js +app.use('/graphql', graphqlHTTP(async (request, response, graphQLParams) => ({ + schema: MyGraphQLSchema, + rootValue: await someFunctionToGetRootValue(request) + graphiql: true +}))); +``` + + +## HTTP Usage + +Once installed at a path, `express-graphql` will accept requests with +the parameters: + + * **`query`**: A string GraphQL document to be executed. + + * **`variables`**: The runtime values to use for any GraphQL query variables + as a JSON object. + + * **`operationName`**: If the provided `query` contains multiple named + operations, this specifies which operation should be executed. If not + provided, a 400 error will be returned if the `query` contains multiple + named operations. + + * **`raw`**: If the `graphiql` option is enabled and the `raw` parameter is + provided raw JSON will always be returned instead of GraphiQL even when + loaded from a browser. + +GraphQL will first look for each parameter in the URL's query-string: + +``` +/graphql?query=query+getUser($id:ID){user(id:$id){name}}&variables={"id":"4"} +``` + +If not found in the query-string, it will look in the POST request body. + +If a previous middleware has already parsed the POST body, the `request.body` +value will be used. Use [`multer`][] or a similar middleware to add support +for `multipart/form-data` content, which may be useful for GraphQL mutations +involving uploading files. See an [example using multer](https://github.com/graphql/express-graphql/blob/304b24b993c8f16fffff8d23b0fa4088e690874b/src/__tests__/http-test.js#L674-L741). + +If the POST body has not yet been parsed, express-graphql will interpret it +depending on the provided *Content-Type* header. + + * **`application/json`**: the POST body will be parsed as a JSON + object of parameters. + + * **`application/x-www-form-urlencoded`**: this POST body will be + parsed as a url-encoded string of key-value pairs. + + * **`application/graphql`**: The POST body will be parsed as GraphQL + query string, which provides the `query` parameter. + + +## Combining with Other Express Middleware + +By default, the express request is passed as the GraphQL `context`. +Since most express middleware operates by adding extra data to the +request object, this means you can use most express middleware just by inserting it before `graphqlHTTP` is mounted. This covers scenarios such as authenticating the user, handling file uploads, or mounting GraphQL on a dynamic endpoint. + +This example uses [`express-session`][] to provide GraphQL with the currently logged-in session. + +```js +const session = require('express-session'); +const graphqlHTTP = require('express-graphql'); + +const app = express(); + +app.use(session({ secret: 'keyboard cat', cookie: { maxAge: 60000 }})); + +app.use('/graphql', graphqlHTTP({ + schema: MySessionAwareGraphQLSchema, + graphiql: true +})); +``` + +Then in your type definitions, you can access the request via the third "context" argument in your `resolve` function: + +```js +new GraphQLObjectType({ + name: 'MyType', + fields: { + myField: { + type: GraphQLString, + resolve(parentValue, args, request) { + // use `request.session` here + } + } + } +}); +``` + + +## Providing Extensions + +The GraphQL response allows for adding additional information in a response to +a GraphQL query via a field in the response called `"extensions"`. This is added +by providing an `extensions` function when using `graphqlHTTP`. The function +must return a JSON-serializable Object. + +When called, this is provided an argument which you can use to get information +about the GraphQL request: + +`{ document, variables, operationName, result }` + +This example illustrates adding the amount of time consumed by running the +provided query, which could perhaps be used by your development tools. + +```js +const graphqlHTTP = require('express-graphql'); + +const app = express(); + +app.use(session({ secret: 'keyboard cat', cookie: { maxAge: 60000 }})); + +app.use('/graphql', graphqlHTTP(request => { + const startTime = Date.now(); + return { + schema: MyGraphQLSchema, + graphiql: true, + extensions({ document, variables, operationName, result }) { + return { runTime: Date.now() - startTime }; + } + }; +})); +``` + +When querying this endpoint, it would include this information in the result, +for example: + +```js +{ + "data": { ... } + "extensions": { + "runTime": 135 + } +} +``` + + +## Additional Validation Rules + +GraphQL's [validation phase](https://facebook.github.io/graphql/#sec-Validation) checks the query to ensure that it can be successfully executed against the schema. The `validationRules` option allows for additional rules to be run during this phase. Rules are applied to each node in an AST representing the query using the Visitor pattern. + +A validation rule is a function which returns a visitor for one or more node Types. Below is an example of a validation preventing the specific fieldname `metadata` from being queried.

That overview +describes a simple set of GraphQL examples that exist as [tests](src/__tests__) +in this repository. A good way to get started with this repository is to walk +through that README and the corresponding tests in parallel. + +### Using GraphQL.js + +Install GraphQL.js from npm + +With yarn: + +```sh +yarn add graphql +``` + +or alternatively using npm: + +```sh +npm install --save graphql +``` + +GraphQL.js provides two important capabilities: building a type schema, and +serving queries against that type schema. + +First, build a GraphQL type schema which maps to your code base. + +```js +import { + graphql, + GraphQLSchema, + GraphQLObjectType, + GraphQLString +} from 'graphql'; + +var schema = new GraphQLSchema({ + query: new GraphQLObjectType({ + name: 'RootQueryType', + fields: { + hello: { + type: GraphQLString, + resolve() { + return 'world'; + } + } + } + }) +}); +``` + +This defines a simple schema with one type and one field, that resolves +to a fixed value. The `resolve` function can return a value, a promise, +or an array of promises. A more complex example is included in the top +level [tests](src/__tests__) directory. + +Then, serve the result of a query against that type schema. + +```js +var query = '{ hello }'; + +graphql(schema, query).then(result => { + + // Prints + // { + // data: { hello: "world" } + // } + console.log(result); + +}); +``` + +This runs a query fetching the one field defined. The `graphql` function will +first ensure the query is syntactically and semantically valid before executing +it, reporting errors otherwise. + +```js +var query = '{ boyhowdy }'; + +graphql(schema, query).then(result => { + + // Prints + // { + // errors: [ + // { message: 'Cannot query field boyhowdy on RootQueryType', + // locations: [ { line: 1, column: 3 } ] } + // ] + // } + console.log(result); + +}); +``` + +### Want to ride the bleeding edge? + +The `npm` branch in this repository is automatically maintained to be the last +commit to `master` to pass all tests, in the same form found on npm. It is +recommended to use builds deployed to npm for many reasons, but if you want to use +the latest not-yet-released version of graphql-js, you can do so by depending +directly on this branch: + +``` +npm install graphql@git://github.com/graphql/graphql-js.git#npm +``` + +### Using in a Browser + +GraphQL.js is a general purpose library and can be used both in a Node server +and in the browser. As an example, the [GraphiQL](https://github.com/graphql/graphiql/) +tool is built with GraphQL.js! + +Building a project using GraphQL.js with [webpack](https://webpack.js.org) or +[rollup](https://github.com/rollup/rollup) should just work and only include +the portions of the library you use. This works because GraphQL.js is distributed +with both CommonJS (`require()`) and ESModule (`import`) files. Ensure that any +custom build configurations look for `.mjs` files! + +### Contributing + +We actively welcome pull requests, learn how to +[contribute](https://github.com/graphql/graphql-js/blob/master/.github/CONTRIBUTING.md). + +### Changelog + +Changes are tracked as [GitHub releases](https://github.com/graphql/graphql-js/releases). + +### License + +GraphQL.js is [MIT-licensed](https://github.com/graphql/graphql-js/blob/master/LICENSE). diff --git a/node_modules/graphql/error/GraphQLError.js b/node_modules/graphql/error/GraphQLError.js new file mode 100644 index 00000000..f9d53470 --- /dev/null +++ b/node_modules/graphql/error/GraphQLError.js @@ -0,0 +1,146 @@ +"use strict"; + +Object.defineProperty(exports, "__esModule", { + value: true +}); +exports.GraphQLError = GraphQLError; + +var _printError = require("./printError"); + +var _location = require("../language/location"); + +/** + * Copyright (c) 2015-present, Facebook, Inc. + * + * This source code is licensed under the MIT license found in the + * LICENSE file in the root directory of this source tree. + * + * strict + */ +function GraphQLError( // eslint-disable-line no-redeclare +message, nodes, source, positions, path, originalError, extensions) { + // Compute list of blame nodes. + var _nodes = Array.isArray(nodes) ? nodes.length !== 0 ? nodes : undefined : nodes ?

It runs on both CommonJS runtimes +(e.g. [nodejs]) and in a web browser. + +ipaddr.js allows you to verify and parse string representation of an IP +address, match it against a CIDR range or range list, determine if it falls +into some reserved ranges (examples include loopback and private ranges), +and convert between IPv4 and IPv4-mapped IPv6 addresses. + +[nodejs]: http://nodejs.org + +## Installation + +`npm install ipaddr.js` + +or + +`bower install ipaddr.js` + +## API + +ipaddr.js defines one object in the global scope: `ipaddr`.

All of them receive a string as a single parameter. + +The `ipaddr.isValid` method returns `true` if the address is a valid IPv4 or +IPv6 address, and `false` otherwise. It does not throw any exceptions. + +The `ipaddr.parse` method returns an object representing the IP address, +or throws an `Error` if the passed string is not a valid representation of an +IP address. + +The `ipaddr.process` method works just like the `ipaddr.parse` one, but it +automatically converts IPv4-mapped IPv6 addresses to their IPv4 counterparts +before returning. It is useful when you have a Node.js instance listening +on an IPv6 socket, and the `net.ivp6.bindv6only` sysctl parameter (or its +equivalent on non-Linux OS) is set to 0. In this case, you can accept IPv4 +connections on your IPv6-only socket, but the remote address will be mangled. +Use `ipaddr.process` method to automatically demangle it. + +### Object representation + +Parsing methods return an object which descends from `ipaddr.IPv6` or +`ipaddr.IPv4`. These objects share some properties, but most of them differ. + +#### Shared properties + +One can determine the type of address by calling `addr.kind()`. It will return +either `"ipv6"` or `"ipv4"`. + +An address can be converted back to its string representation with `addr.toString()`. +Note that this method: + * does not return the original string used to create the object (in fact, there is + no way of getting that string) + * returns a compact representation (when it is applicable) + +A `match(range, bits)` method can be used to check if the address falls into a +certain CIDR range. +Note that an address can be (obviously) matched only against an address of the same type. + +For example: + +```js +var addr = ipaddr.parse("2001:db8:1234::1"); +var range = ipaddr.parse("2001:db8::"); + +addr.match(range, 32); // => true +``` + +Alternatively, `match` can also be called as `match([range, bits])`. In this way, +it can be used together with the `parseCIDR(string)` method, which parses an IP +address together with a CIDR range. + +For example: + +```js +var addr = ipaddr.parse("2001:db8:1234::1"); + +addr.match(ipaddr.parseCIDR("2001:db8::/32")); // => true +``` + +A `range()` method returns one of predefined names for several special ranges defined +by IP protocols. The exact names (and their respective CIDR ranges) can be looked up +in the source: [IPv6 ranges] and [IPv4 ranges]. Some common ones include `"unicast"` +(the default one) and `"reserved"`. + +You can match against your own range list by using +`ipaddr.subnetMatch(address, rangeList, defaultName)` method. It can work with a mix of IPv6 or IPv4 addresses, and accepts a name-to-subnet map as the range list. For example: + +```js +var rangeList = { + documentationOnly: [ ipaddr.parse('2001:db8::'), 32 ], + tunnelProviders: [ + [ ipaddr.parse('2001:470::'), 32 ], // he.net + [ ipaddr.parse('2001:5c0::'), 32 ] // freenet6 + ] +}; +ipaddr.subnetMatch(ipaddr.parse('2001:470:8:66::1'), rangeList, 'unknown'); // => "tunnelProviders" +``` + +The addresses can be converted to their byte representation with `toByteArray()`. +(Actually, JavaScript mostly does not know about byte buffers. They are emulated with +arrays of numbers, each in range of 0..255.) + +```js +var bytes = ipaddr.parse('2a00:1450:8007::68').toByteArray(); // ipv6.google.com +bytes // => [42, 0x00, 0x14, 0x50, 0x80, 0x07, 0x00, , 0x00, 0x68 ] +``` + +The `ipaddr.IPv4` and `ipaddr.IPv6` objects have some methods defined, too. All of them +have the same interface for both protocols, and are similar to global methods. + +`ipaddr.IPvX.isValid(string)` can be used to check if the string is a valid address +for particular protocol, and `ipaddr.IPvX.parse(string)` is the error-throwing parser. + +`ipaddr.IPvX.isValid(string)` uses the same format for parsing as the POSIX `inet_ntoa` function, which accepts unusual formats like `0xc0.168.1.1` or `0x10000000`. The function `ipaddr.IPv4.isValidFourPartDecimal(string)` validates the IPv4 address and also ensures that it is written in four-part decimal format. + +[IPv6 ranges]: https://github.com/whitequark/ipaddr.js/blob/master/src/ipaddr.coffee#L186 +[IPv4 ranges]: https://github.com/whitequark/ipaddr.js/blob/master/src/ipaddr.coffee#L71 + +#### IPv6 properties + +Sometimes you will want to convert IPv6 not to a compact string representation (with +the `::` substitution); the `toNormalizedString()` method will return an address where +all zeroes are explicit. + +For example: + +```js +var addr = ipaddr.parse("2001:0db8::0001"); +addr.toString(); // => "2001:db8::1" +addr.toNormalizedString(); // => "2001:db8:0:0:0:0:0:1" +``` + +The `isIPv4MappedAddress()` method will return `true` if this address is an IPv4-mapped +one, and `toIPv4Address()` will return an IPv4 object address. + +To access the underlying binary representation of the address, use `addr.parts`. + +```js +var addr = ipaddr.parse("2001:db8:10::1234:DEAD"); +addr.parts // => [0x2001, 0xdb8, 0x10, 0, 0, 0, 0x1234, 0xdead] +``` + +A IPv6 zone index can be accessed via `addr.zoneId`: + +```js +var addr = ipaddr.parse("2001:db8::%eth0"); +addr.zoneId // => 'eth0' +``` + +#### IPv4 properties + +`toIPv4MappedAddress()` will return a corresponding IPv4-mapped IPv6 address. + +To access the underlying representation of the address, use `addr.octets`. + +```js +var addr = ipaddr.parse("192.168.1.1"); +addr.octets // => [192, 168, 1, 1] +``` + +`prefixLengthFromSubnetMask()` will return a CIDR prefix length for a valid IPv4 netmask or +false if the netmask is not valid. + +```js +ipaddr.IPv4.parse('255.255.255.240').prefixLengthFromSubnetMask() == 28 +ipaddr.IPv4.parse('255.192.164.0').prefixLengthFromSubnetMask() == null +``` + +`subnetMaskFromPrefixLength()` will return an IPv4 netmask for a valid CIDR prefix length. + +```js +ipaddr.IPv4.subnetMaskFromPrefixLength(24) == "255.255.255.0" +ipaddr.IPv4.subnetMaskFromPrefixLength(29) == "255.255.255.248" +``` + +`broadcastAddressFromCIDR()` will return the broadcast address for a given IPv4 interface and netmask in CIDR notation. +```js +ipaddr.IPv4.broadcastAddressFromCIDR("172.0.0.1/24") == "172.0.0.255" +``` +`networkAddressFromCIDR()` will return the network address for a given IPv4 interface and netmask in CIDR notation. +```js +ipaddr.IPv4.networkAddressFromCIDR("172.0.0.1/24") == "172.0.0.0" +``` + +#### Conversion + +IPv4 and IPv6 can be converted bidirectionally to and from network byte order (MSB) byte arrays. + +The `fromByteArray()` method will take an array and create an appropriate IPv4 or IPv6 object +if the input satisfies the requirements.

These collections can conceptually describe nearly +all data and so it's no suprise that libraries expecting lists of +things standardized on expecting and checking for an Array. This pattern even +resulted in the addition of a new method in ES5: [`Array.isArray()`][isarray]. + +As JavaScript applications grew in complexity, moved to the [server][nodejs] +where CPU is a constrained resource, faced new problems and implemented new +algorithms, new data-structures are often required. With options from +[linked lists][linked list] to [HAMTs][hamt] developers can use what is most +efficient and provides the right properties for their program. + +However none of these new data-structures can be used in libraries where an +`Array` is expected, which means developers are often stuck between abandoning +their favorite libraries or limiting their data-structure choices at the cost of +efficiency or usefulness. + +To enable many related data-structures to be used interchangably we need a +_[protocol][]_, and luckily for us ES2015 introduced the +[Iteration Protocols][iterators] to describe all list-like data-structures which +can be iterated. That includes not just the new-to-ES2015 [Map][] and [Set][] +collections but also existing ones like [arguments][], [NodeList][] and the +various [TypedArray][], all of which return `false` for [`Array.isArray()`][isarray] +and in ES2015 implement the [Iterator protocol][iterators]. + +While Iterators are defined in ES2015, they _do not require_ ES2015 to work +correctly. In fact, Iterators were first introduced in 2012 in [Firefox v17](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols#Iterator_property_and_iterator_symbol). Rather than using [`Symbol.iterator`][symbol.iterator], they used the property name `"@@iterator"` (in fact, the ECMAScript +spec still refers to well-known `Symbols` using this `@@` shorthand). By falling +back to use `"@@iterator"` when `Symbol.iterator` is not defined, Iterators can +be both safely defined and used by _any version of JavaScript_. + +Not only were Iterables defined in ES2015, they were also implemented by the +built-in data-structures including [Array][array#@@iterator]. Older JavaScript +environments do not implement `Array.prototype[@@iterator]()`, however this is +only a minor problem. JavaScript has another related and much older protocol: +[Array-like]. A value is "Array-like" if it has a numeric `length` property and +indexed access, but does not necessarily have methods like `.push()` or `.forEach()`. +Much like [`Array.from`][array.from], `iterall`'s `forEach()` and +`createIterator()` methods also accept collections which are not Iterable but +are Array-like. This means that `iterall` can be used with [Array][], +[arguments][], [NodeList][], [TypedArray][] and other Array-like collections +regardless of the JavaScript environment. + +When libraries only accept Arrays as input, they stick developers with a tough +choice: limit which data-structures can be used or limit the ability to use that +library. Accepting Iterables removes this false dichotomy, and allows libraries +to be more generally useful. There's no need to limit to ES2015 environments and +bleeding-edge browsers to accept `Iterable`. + +Only using Arrays can limit the efficiency and usefulness of your application +code, but custom data-structures can often feel like a fish out of water in +JavaScript programs, only working with code written specifically for it. +Protocols like `Iterable` helps these new data-structures work with more +libraries and built-in JavaScript behavior. There's no need to limit to ES2015 +environments and bleeding-edge browsers to implement `Iterable`. + +## Why use AsyncIterators? + +In the same way that `Iterator` provides a common interface for accessing many +different kinds of data-structures, `AsyncIterator` provides a common interface +over an asynchronous sequence of values (similar to Stream or Observable). + +Async Iterators are not yet an official part of JavaScript, however they're +a "Stage 3" proposal to be added, and browser vendors are +[working on adding support](https://bugs.chromium.org/p/v8/issues/detail?id=5855). +However, Async Iterators can be both safely defined and used today by +_any version of JavaScript_, by using the utilities in `iterall`. + +## FAQ + +> Aren't Iterables slower than Arrays? I want the highest performance possible. + +Arrays _are_ Iterables. Iterable is a protocol that Arrays adhere to in ES2015. +It's true that creating an Iterator and stepping through it can present some +overhead compared to a simple for-loop or `array.forEach`. However `iterall`'s +`forEach` will delegate directly to `array.forEach` and will use a for-loop for +Array-like objects, ensuring the best performance for Arrays while still +maintaining support for all Iterables. + +> Should my library functions also return Iterables instead of Arrays? Won't +> that be limiting? + +That could definitely be limiting if you return some generic Iterable where you +could have returned an Array, and (depending on context) I wouldn't recommend +you stop returning Arrays from functions if that's what you're doing today. +However if your functions are returning some collection data-structure that is +_not_ an Array, you should certainly consider having them implement the +Iterable protocol so they can be more widely useful. + +Here are a few examples: + +In [React][], render functions are expected to return view trees, where any +node (e.g. a `
    `) can have many children (e.g. many `
  • `). While it could +expect those children to always be represented as an Array, that would limit +React's usefulness - other data-structures couldn't be used. Instead, React +expects those children to be represented as an _Iterable_. That allows it to +continue to accept Arrays, but also accept many other data-structures. + +[Immutable.js][] implements many new kinds of data-structures (including [HAMT]) +all of which implement _Iterable_, which allows them to be used in many of +JavaScript's built-in functions, but also allows them to be used by many +libraries which accept Iterables, including React. Also, similar to +[`Array.from`][array.from], Immutable.js's constructors accept not only Arrays, +but any _Iterable_, allowing you to build any of these new data-structures from +any other data-structure. + +> Where are all the other functions like `map`, `filter`, and `reduce`? + +Those "higher order" collection functions are awesome, but they don't belong in +this library. Instead this library should be used as a basis for building such +a library (as it should be used for many other libraries). The `forEach` +function provided by `iterall` can be used as the underpinning for these. + +As an example: + +```js +function reduce (collection, reducer, initial) { + var reduced = initial + forEach(collection, function (item) { + reduced = reducer(reduced, item) + }) + return reduced +} +``` + +> How do I break out of a `forEach` or `forAwaitEach` loop early? + +While `for of` and `for await of` loops allow breaking out of a loop early with +a `break` statement, the `forEach()` and `forAwaitEach()` functions (much like +Array's `forEach`) do not support early breaking. + +Similar to the "higher order" functions described above, this library can be the +basis for this extended behavior. To support early break outs, you can use a +wrapping function supporting early breaking by throwing a `BREAK` sentinel value +from the callback and using a try/catch block to early break: + +```js +const BREAK = {} + +function forEachBreakable (collection, callback) { + try { + forEach(collection, callback) + } catch (error) { + if (error !== BREAK) { + throw error + } + } +} + +async function forAwaitEachBreakable (collection, callback) { + try { + await forAwaitEach(collection, callback) + } catch (error) { + if (error !== BREAK) { + throw error + } + } +} + +// Example usages: +forEachBreakable(obj, function (value) { + if (shouldBreakOn(value)) { + throw BREAK + } + console.log(value) +}) + +forAwaitEachBreakable(obj, async function (value) { + if (await shouldBreakOn(value)) { + throw BREAK + } + console.log(value) +}) +``` + +Note: This technique also works with the native Array `forEach` method! + + + +## API + + + +#### Table of Contents + +- [Iterable](#iterable) +- [Iterator](#iterator) +- [$$iterator](#iterator-1) +- [isIterable](#isiterable) +- [isArrayLike](#isarraylike) +- [isCollection](#iscollection) +- [getIterator](#getiterator) +- [getIteratorMethod](#getiteratormethod) +- [createIterator](#createiterator) +- [forEach](#foreach) +- [AsyncIterable](#asynciterable) +- [AsyncIterator](#asynciterator) +- [$$asyncIterator](#asynciterator-1) +- [isAsyncIterable](#isasynciterable) +- [getAsyncIterator](#getasynciterator) +- [getAsyncIteratorMethod](#getasynciteratormethod) +- [createAsyncIterator](#createasynciterator) +- [forAwaitEach](#forawaiteach) + +### Iterable + +- **See: [MDN Iteration protocols](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols#iterable)** + +[Iterable](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols#iterable) +is a _protocol_ which when implemented allows a JavaScript object to define +their iteration behavior, such as what values are looped over in a +[`for...of`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...of) +loop or `iterall`'s `forEach` function.

The closest untrusted address is +returned. + + + +```js +proxyaddr(req, function (addr) { return addr === '127.0.0.1' }) +proxyaddr(req, function (addr, i) { return i < 1 }) +``` + +The `trust` arugment may also be a single IP address string or an +array of trusted addresses, as plain IP addresses, CIDR-formatted +strings, or IP/netmask strings. + + + +```js +proxyaddr(req, '127.0.0.1') +proxyaddr(req, ['127.0.0.0/8', '10.0.0.0/8']) +proxyaddr(req, ['127.0.0.0/255.0.0.0', '192.168.0.0/255.255.0.0']) +``` + +This module also supports IPv6. Your IPv6 addresses will be normalized +automatically (i.e. `fe80::00ed:1` equals `fe80:0:0:0:0:0:ed:1`). + + + +```js +proxyaddr(req, '::1') +proxyaddr(req, ['::1/128', 'fe80::/10']) +``` + +This module will automatically work with IPv4-mapped IPv6 addresses +as well to support node.js in IPv6-only mode. This means that you do +not have to specify both `::ffff:a00:1` and `10.0.0.1`. + +As a convenience, this module also takes certain pre-defined names +in addition to IP addresses, which expand into IP addresses: + + + +```js +proxyaddr(req, 'loopback') +proxyaddr(req, ['loopback', 'fc00:ac:1ab5:fff::1/64']) +``` + + * `loopback`: IPv4 and IPv6 loopback addresses (like `::1` and + `127.0.0.1`). + * `linklocal`: IPv4 and IPv6 link-local addresses (like + `fe80::1:1:1:1` and `169.254.0.1`). + * `uniquelocal`: IPv4 private addresses and IPv6 unique-local + addresses (like `fc00:ac:1ab5:fff::1` and `192.168.0.1`). + +When `trust` is specified as a function, it will be called for each +address to determine if it is a trusted address. The function is +given two arguments: `addr` and `i`, where `addr` is a string of +the address to check and `i` is a number that represents the distance +from the socket address. + +### proxyaddr.all(req, [trust]) + +Return all the addresses of the request, optionally stopping at the +first untrusted. This array is ordered from closest to furthest +(i.e. `arr[0] === req.connection.remoteAddress`). + + + +```js +proxyaddr.all(req) +``` + +The optional `trust` argument takes the same arguments as `trust` +does in `proxyaddr(req, trust)`. + + + +```js +proxyaddr.all(req, 'loopback') +``` + +### proxyaddr.compile(val) + +Compiles argument `val` into a `trust` function. This function takes +the same arguments as `trust` does in `proxyaddr(req, trust)` and +returns a function suitable for `proxyaddr(req, trust)`. + + + +```js +var trust = proxyaddr.compile('loopback') +var addr = proxyaddr(req, trust) +``` + +This function is meant to be optimized for use against every request. +It is recommend to compile a trust function up-front for the trusted +configuration and

Always be careful with this option. + +```javascript +var protoObject = qs.parse('a[hasOwnProperty]=b', { allowPrototypes: true }); +assert.deepEqual(protoObject, { a: { hasOwnProperty: 'b' } }); +``` + +URI encoded strings work too: + +```javascript +assert.deepEqual(qs.parse('a%5Bb%5D=c'), { + a: { b: 'c' } +}); +``` + +You can also nest your objects, like `'foo[bar][baz]=foobarbaz'`: + +```javascript +assert.deepEqual(qs.parse('foo[bar][baz]=foobarbaz'), { + foo: { + bar: { + baz: 'foobarbaz' + } + } +}); +``` + +By default, when nesting objects **qs** will only parse up to 5 children deep. This means if you attempt to parse a string like +`'a[b][c][d][e][f][g][h][i]=j'` your resulting object will be: + +```javascript +var expected = { + a: { + b: { + c: { + d: { + e: { + f: { + '[g][h][i]': 'j' + } + } + } + } + } + } +}; +var string = 'a[b][c][d][e][f][g][h][i]=j'; +assert.deepEqual(qs.parse(string), expected); +``` + +This depth can be overridden by passing a `depth` option to `qs.parse(string, [options])`: + +```javascript +var deep = qs.parse('a[b][c][d][e][f][g][h][i]=j', { depth: 1 }); +assert.deepEqual(deep, { a: { b: { '[c][d][e][f][g][h][i]': 'j' } } }); +``` + +The depth limit helps mitigate abuse when **qs** is used to parse user input, and it is recommended to keep it a reasonably small number. + +For similar reasons, by default **qs** will only parse up to 1000 parameters. This can be overridden by passing a `parameterLimit` option: + +```javascript +var limited = qs.parse('a=b&c=d', { parameterLimit: 1 }); +assert.deepEqual(limited, { a: 'b' }); +``` + +To bypass the leading question mark, use `ignoreQueryPrefix`: + +```javascript +var prefixed = qs.parse('?a=b&c=d', { ignoreQueryPrefix: true }); +assert.deepEqual(prefixed, { a: 'b', c: 'd' }); +``` + +An optional delimiter can also be passed: + +```javascript +var delimited = qs.parse('a=b;c=d', { delimiter: ';' }); +assert.deepEqual(delimited, { a: 'b', c: 'd' }); +``` + +Delimiters can be a regular expression too: + +```javascript +var regexed = qs.parse('a=b;c=d,e=f', { delimiter: /[;,]/ }); +assert.deepEqual(regexed, { a: 'b', c: 'd', e: 'f' }); +``` + +Option `allowDots` can be used to enable dot notation: + +```javascript +var withDots = qs.parse('a.b=c', { allowDots: true }); +assert.deepEqual(withDots, { a: { b: 'c' } }); +``` + +### Parsing Arrays + +**qs** can also parse arrays using a similar `[]` notation: + +```javascript +var withArray = qs.parse('a[]=b&a[]=c'); +assert.deepEqual(withArray, { a: ['b', 'c'] }); +``` + +You may specify an index as well: + +```javascript +var withIndexes = qs.parse('a[1]=c&a[0]=b'); +assert.deepEqual(withIndexes, { a: ['b', 'c'] }); +``` + +Note that the only difference between an index in an array and a key in an object is that the value between the brackets must be a number +to create an array. When creating arrays with specific indices, **qs** will compact a sparse array to only the existing values preserving +their order: + +```javascript +var noSparse = qs.parse('a[1]=b&a[15]=c'); +assert.deepEqual(noSparse, { a: ['b', 'c'] }); +``` + +Note that an empty string is also a value, and will be preserved: + +```javascript +var withEmptyString = qs.parse('a[]=&a[]=b'); +assert.deepEqual(withEmptyString, { a: ['', 'b'] }); + +var withIndexedEmptyString = qs.parse('a[0]=b&a[1]=&a[2]=c'); +assert.deepEqual(withIndexedEmptyString, { a: ['b', '', 'c'] }); +``` + +**qs** will also limit specifying indices in an array to a maximum index of `20`. Any array members with an index of greater than `20` will +instead be converted to an object with the index as the key: + +```javascript +var withMaxIndex = qs.parse('a[100]=b'); +assert.deepEqual(withMaxIndex, { a: { '100': 'b' } }); +``` + +This limit can be overridden by passing an `arrayLimit` option: + +```javascript +var withArrayLimit = qs.parse('a[1]=b', { arrayLimit: 0 }); +assert.deepEqual(withArrayLimit, { a: { '1': 'b' } }); +``` + +To disable array parsing entirely, set `parseArrays` to `false`. + +```javascript +var noParsingArrays = qs.parse('a[]=b', { parseArrays: false }); +assert.deepEqual(noParsingArrays, { a: { '0': 'b' } }); +``` + +If you mix notations, **qs** will merge the two items into an object: + +```javascript +var mixedNotation = qs.parse('a[0]=b&a[b]=c'); +assert.deepEqual(mixedNotation, { a: { '0': 'b', b: 'c' } }); +``` + +You can also create arrays of objects: + +```javascript +var arraysOfObjects = qs.parse('a[][b]=c'); +assert.deepEqual(arraysOfObjects, { a: [{ b: 'c' }] }); +``` + +### Stringifying + +[](#preventEval) +```javascript +qs.stringify(object, [options]); +``` + +When stringifying, **qs** by default URI encodes output. Objects are stringified as you would expect: + +```javascript +assert.equal(qs.stringify({ a: 'b' }), 'a=b'); +assert.equal(qs.stringify({ a: { b: 'c' } }), 'a%5Bb%5D=c'); +``` + +This encoding can be disabled by setting the `encode` option to `false`: + +```javascript +var unencoded = qs.stringify({ a: { b: 'c' } }, { encode: false }); +assert.equal(unencoded, 'a[b]=c'); +``` + +Encoding can be disabled for keys by setting the `encodeValuesOnly` option to `true`: +```javascript +var encodedValues = qs.stringify( + { a: 'b', c: ['d', 'e=f'], f: [['g'], ['h']] }, + { encodeValuesOnly: true } +); +assert.equal(encodedValues,'a=b&c[0]=d&c[1]=e%3Df&f[0][0]=g&f[1][0]=h'); +``` + +This encoding can also be replaced by a custom encoding method set as `encoder` option: + +```javascript +var encoded = qs.stringify({ a: { b: 'c' } }, { encoder: function (str) { + // Passed in values `a`, `b`, `c` + return // Return encoded string +}}) +``` + +_(Note: the `encoder` option does not apply if `encode` is `false`)_ + +Analogue to the `encoder` there is a `decoder` option for `parse` to override decoding of properties and values: + +```javascript +var decoded = qs.parse('x=z', { decoder: function (str) { + // Passed in values `x`, `z` + return // Return decoded string +}}) +``` + +Examples beyond this point will be shown as though the output is not URI encoded for clarity. Please note that the return values in these cases *will* be URI encoded during real usage. + +When arrays are stringified, by default they are given explicit indices: + +```javascript +qs.stringify({ a: ['b', 'c', 'd'] }); +// 'a[0]=b&a[1]=c&a[2]=d' +``` + +You may override this by setting the `indices` option to `false`: + +```javascript +qs.stringify({ a: ['b', 'c', 'd'] }, { indices: false }); +// 'a=b&a=c&a=d' +``` + +You may use the `arrayFormat` option to specify the format of the output array: + +```javascript +qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'indices' }) +// 'a[0]=b&a[1]=c' +qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'brackets' }) +// 'a[]=b&a[]=c' +qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'repeat' }) +// 'a=b&a=c' +``` + +When objects are stringified, by default they use bracket notation: + +```javascript +qs.stringify({ a: { b: { c: 'd', e: 'f' } } }); +// 'a[b][c]=d&a[b][e]=f' +``` + +You may override this to use dot notation by setting the `allowDots` option to `true`: + +```javascript +qs.stringify({ a: { b: { c: 'd', e: 'f' } } }, { allowDots: true }); +// 'a.b.c=d&a.b.e=f' +``` + +Empty strings and null values will omit the value, but the equals sign (=) remains in place: + +```javascript +assert.equal(qs.stringify({ a: '' }), 'a='); +``` + +Key with no values (such as an empty object or array) will return nothing: + +```javascript +assert.equal(qs.stringify({ a: [] }), ''); +assert.equal(qs.stringify({ a: {} }), ''); +assert.equal(qs.stringify({ a: [{}] }), ''); +assert.equal(qs.stringify({ a: { b: []} }), ''); +assert.equal(qs.stringify({ a: { b: {}} }), ''); +``` + +Properties that are set to `undefined` will be omitted entirely: + +```javascript +assert.equal(qs.stringify({ a: null, b: undefined }), 'a='); +``` + +The query string may optionally be prepended with a question mark: + +```javascript +assert.equal(qs.stringify({ a: 'b', c: 'd' }, { addQueryPrefix: true }), '?a=b&c=d'); +``` + +The delimiter may be overridden with stringify as well: + +```javascript +assert.equal(qs.stringify({ a: 'b', c: 'd' }, { delimiter: ';' }), 'a=b;c=d'); +``` + +If you only want to override the serialization of `Date` objects, you can provide a `serializeDate` option: + +```javascript +var date = new Date(7); +assert.equal(qs.stringify({ a: date }), 'a=1970-01-01T00:00:00.007Z'.replace(/:/g, '%3A')); +assert.equal( + qs.stringify({ a: date }, { serializeDate: function (d) { return d.getTime(); } }), + 'a=7' +); +``` + +You may use the `sort` option to affect the order of parameter keys: + +```javascript +function alphabeticalSort(a, b) { + return a.localeCompare(b); +} +assert.equal(qs.stringify({ a: 'c', z: 'y', b : 'f' }, { sort: alphabeticalSort }), 'a=c&b=f&z=y'); +``` + +Finally, you can use the `filter` option to restrict which keys will be included in the stringified output. +If you pass a function, it will be called for each key to obtain the replacement value. Otherwise, if you +pass an array, it will be used to select properties and array indices for stringification: + +```javascript +function filterFunc(prefix, value) { + if (prefix == 'b') { + // Return an `undefined` value to omit a property. + return; + } + if (prefix == 'e[f]') { + return value.getTime(); + } + if (prefix == 'e[g][0]') { + return value * 2; + } + return value; +} +qs.stringify({ a: 'b', c: 'd', e: { f: new Date(123), g: [2] } }, { filter: filterFunc }); +// 'a=b&c=d&e[f]=123&e[g][0]=4' +qs.stringify({ a: 'b', c: 'd', e: 'f' }, { filter: ['a', 'e'] }); +// 'a=b&e=f' +qs.stringify({ a: ['b', 'c', 'd'], e: 'f' }, { filter: ['a', 0, 2] }); +// 'a[0]=b&a[2]=d' +``` + +### Handling of `null` values + +By default, `null` values are treated like empty strings: + +```javascript +var withNull = qs.stringify({ a: null, b: '' }); +assert.equal(withNull, 'a=&b='); +``` + +Parsing does not distinguish between parameters with and without equal signs. Both are converted to empty strings. + +```javascript +var equalsInsensitive = qs.parse('a&b='); +assert.deepEqual(equalsInsensitive, { a: '', b: '' }); +``` + +To distinguish between `null` values and empty strings use the `strictNullHandling` flag. In the result string the `null` +values have no `=` sign: + +```javascript +var strictNull = qs.stringify({ a: null, b: '' }, { strictNullHandling: true }); +assert.equal(strictNull, 'a&b='); +``` + +To parse values without `=` back to `null` use the `strictNullHandling` flag: + +```javascript +var parsedStrictNull = qs.parse('a&b=', { strictNullHandling: true }); +assert.deepEqual(parsedStrictNull, { a: null, b: '' }); +``` + +To completely skip rendering keys with `null` values, use the `skipNulls` flag: + +```javascript +var nullsSkipped = qs.stringify({ a: 'b', c: null}, { skipNulls: true }); +assert.equal(nullsSkipped, 'a=b'); +``` + +### Dealing with special character sets + +By default the encoding and decoding of characters is done in `utf-8`. If you +wish to encode querystrings to a different character set (i.e. +[Shift JIS](https://en.wikipedia.org/wiki/Shift_JIS)) you can use the +[`qs-iconv`](https://github.com/martinheidegger/qs-iconv) library: + +```javascript +var encoder = require('qs-iconv/encoder')('shift_jis'); +var shiftJISEncoded = qs.stringify({ a: 'こんにちは！' }, { encoder: encoder }); +assert.equal(shiftJISEncoded, 'a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I'); +``` + +This also works for decoding of query strings: + +```javascript +var decoder = require('qs-iconv/decoder')('shift_jis'); +var obj = qs.parse('a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I', { decoder: decoder }); +assert.deepEqual(obj, { a: 'こんにちは！' }); +``` + +### RFC 3986 and RFC 1738 space encoding + +RFC3986 used as default option and encodes ' ' to *%20* which is backward compatible. +In the same time, output can be stringified as per RFC1738 with ' ' equal to '+'. + +``` +assert.equal(qs.stringify({ a: 'b c' }), 'a=b%20c'); +assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC3986' }), 'a=b%20c'); +assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC1738' }), 'a=b+c'); +``` + +[1]: https://npmjs.org/package/qs +[2]: http://versionbadg.es/ljharb/qs.svg +[3]: https://api.travis-ci.org/ljharb/qs.svg +[4]: https://travis-ci.org/ljharb/qs +[5]: https://david-dm.org/ljharb/qs.svg +[6]: https://david-dm.org/ljharb/qs +[7]: https://david-dm.org/ljharb/qs/dev-status.svg +[8]: https://david-dm.org/ljharb/qs?type=dev +[9]: https://ci.testling.com/ljharb/qs.png +[10]: https://ci.testling.com/ljharb/qs +[11]: https://nodei.co/npm/qs.png?downloads=true&stars=true +[license-image]: http://img.shields.io/npm/l/qs.svg +[license-url]: LICENSE +[downloads-image]: http://img.shields.io/npm/dm/qs.svg +[downloads-url]: http://npm-stat.com/charts.html?package=qs diff --git a/node_modules/qs/dist/qs.js b/node_modules/qs/dist/qs.js new file mode 100644 index 00000000..713c6d1e --- /dev/null +++ b/node_modules/qs/dist/qs.js @@ -0,0 +1,627 @@ +(function(f){if(typeof exports==="object"&&typeof module!=="undefined"){module.exports=f()}else if(typeof define==="function"&&define.amd){define([],f)}else{var g;if(typeof window!=="undefined"){g=window}else if(typeof global!=="undefined"){g=global}else if(typeof self!=="undefined"){g=self}else{g=this}g.Qs = f()}})(function(){var define,module,exports;return (function e(t,n,r){function s(o,u){if(!n[o]){if(!t[o]){var a=typeof require=="function"&&require;if(!u&&a)return a(o,!0);if(i)return i(o,!0);var f=new Error("Cannot find module '"+o+"'");throw f.code="MODULE_NOT_FOUND",f}var l=n[o]={exports:{}};t[o][0].call(l.exports,function(e){var n=t[o][1][e];return s(n?n:e)},l,l.exports,e,t,n,r)}return n[o].exports}var i=typeof require=="function"&&require;for(var o=0;o= 0; --i) { + var obj; + var root = chain[i]; + + if (root === '[]') { + obj = []; + obj = obj.concat(leaf); + } else { + obj = options.plainObjects ?

Install + +This module is installed directly using `npm`: + +```sh +$ npm install depd +``` + +This module can also be bundled with systems like +[Browserify](http://browserify.org/) or [webpack](https://webpack.github.io/), +though by default this module will alter it's API to no longer display or +track deprecations. + +## API + + + +```js +var deprecate = require('depd')('my-module') +``` + +This library allows you to display deprecation messages to your users. +This library goes above and beyond with deprecation warnings by +introspection of the call stack (but only the bits that it is interested +in). + +Instead of just warning on the first invocation of a deprecated +function and never again, this module will warn on the first invocation +of a deprecated function per unique call site, making it ideal to alert +users of all deprecated uses across the code base, rather than just +whatever happens to execute first. + +The deprecation warnings from this module also include the file and line +information for the call into the module that the deprecated function was +in. + +**NOTE** this library has a similar interface to the `debug` module, and +this module uses the calling file to get the boundary for the call stacks, +so you should always create a new `deprecate` object in each file and not +within some central file. + +### depd(namespace) + +Create a new deprecate function that uses the given namespace name in the +messages and will display the call site prior to the stack entering the +file this function was called from. It is highly suggested you use the +name of your module as the namespace. + +### deprecate(message) + +Call this function from deprecated code to display a deprecation message. +This message will appear once per unique caller site. Caller site is the +first call site in the stack in a different file from the caller of this +function. + +If the message is omitted, a message is generated for you based on the site +of the `deprecate()` call and will display the name of the function called, +similar to the name displayed in a stack trace. + +### deprecate.function(fn, message) + +Call this function to wrap a given function in a deprecation message on any +call to the function. An optional message can be supplied to provide a custom +message. + +### deprecate.property(obj, prop, message) + +Call this function to wrap a given property on object in a deprecation message +on any accessing or setting of the property. An optional message can be supplied +to provide a custom message. + +The method must be called on the object where the property belongs (not +inherited from the prototype). + +If the property is a data descriptor, it will be converted to an accessor +descriptor in order to display the deprecation message. + +### process.on('deprecation', fn) + +This module will allow easy capturing of deprecation errors by emitting the +errors as the type "deprecation" on the global `process`. If there are no +listeners for this type, the errors are written to STDERR as normal, but if +there are any listeners, nothing will be written to STDERR and instead only +emitted. From there, you can write the errors in a different format or to a +logging source. + +The error represents the deprecation and is emitted only once with the same +rules as writing to STDERR. The error has the following properties: + + - `message` - This is the message given by the library + - `name` - This is always `'DeprecationError'` + - `namespace` - This is the namespace the deprecation came from + - `stack` - This is the stack of the call to the deprecated thing + +Example `error.stack` output: + +``` +DeprecationError: my-cool-module deprecated oldfunction + at Object.

The default +value of `Buffer.poolSize` is `8192` but can be modified. + +Use of this pre-allocated internal memory pool is a key difference between +calling `Buffer.alloc(size, fill)` vs. `Buffer.allocUnsafe(size).fill(fill)`. +Specifically, `Buffer.alloc(size, fill)` will *never* use the internal Buffer +pool, while `Buffer.allocUnsafe(size).fill(fill)` *will* use the internal +Buffer pool if `size` is less than or equal to half `Buffer.poolSize`. The +difference is subtle but can be important when an application requires the +additional performance that `Buffer.allocUnsafe(size)` provides. + +### Class Method: Buffer.allocUnsafeSlow(size) + + +* `size` {Number} + +Allocates a new *non-zero-filled* and non-pooled `Buffer` of `size` bytes. The +`size` must be less than or equal to the value of +`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is +`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown.

The contents of the newly created `Buffer` are unknown and +*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such +`Buffer` instances to zeroes. + +When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances, +allocations under 4KB are, by default, sliced from a single pre-allocated +`Buffer`. This allows applications to avoid the garbage collection overhead of +creating many individually allocated Buffers. This approach improves both +performance and memory usage by eliminating the need to track and cleanup as +many `Persistent` objects. + +However, in the case where a developer may need to retain a small chunk of +memory from a pool for an indeterminate amount of time, it may be appropriate +to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then +copy out the relevant bits. + +```js +// need to keep around a few small chunks of memory +const store = []; + +socket.on('readable', () => { + const data = socket.read(); + // allocate for retained data + const sb = Buffer.allocUnsafeSlow(10); + // copy the data into the new allocation + data.copy(sb, 0, 0, 10); + store.push(sb); +}); +``` + +Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after* +a developer has observed undue memory retention in their applications. + +A `TypeError` will be thrown if `size` is not a number. + +### All the Rest + +The rest of the `Buffer` API is exactly the same as in node.js. +[See the docs](https://nodejs.org/api/buffer.html). + + +## Related links + +- [Node.js issue: Buffer(number) is unsafe](https://github.com/nodejs/node/issues/4660) +- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4) + +## Why is `Buffer` unsafe? + +Today, the node.js `Buffer` constructor is overloaded to handle many different argument +types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.), +`ArrayBuffer`, and also `Number`. + +The API is optimized for convenience: you can throw any type at it, and it will try to do +what you want. + +Because the Buffer constructor is so powerful, you often see code like this: + +```js +// Convert UTF-8 strings to hex +function toHex (str) { + return new Buffer(str).toString('hex') +} +``` + +***But what happens if `toHex` is called with a `Number` argument?*** + +### Remote Memory Disclosure + +If an attacker can make your program call the `Buffer` constructor with a `Number` +argument, then they can make it allocate uninitialized memory from the node.js process. +This could potentially disclose TLS private keys, user data, or database passwords. + +When the `Buffer` constructor is passed a `Number` argument, it returns an +**UNINITIALIZED** block of memory of the specified `size`. When you create a `Buffer` like +this, you **MUST** overwrite the contents before returning it to the user. + +From the [node.js docs](https://nodejs.org/api/buffer.html#buffer_new_buffer_size): + +> `new Buffer(size)` +> +> - `size` Number +> +> The underlying memory for `Buffer` instances created in this way is not initialized. +> **The contents of a newly created `Buffer` are unknown and could contain sensitive +> data.** Use `buf.fill(0)` to initialize a Buffer to zeroes. + +(Emphasis our own.) + +Whenever the programmer intended to create an uninitialized `Buffer` you often see code +like this: + +```js +var buf = new Buffer(16) + +// Immediately overwrite the uninitialized buffer with data from another buffer +for (var i = 0; i < buf.length; i++) { + buf[i] = otherBuf[i] +} +``` + + +### Would this ever be a problem in real code? + +Yes. It's surprisingly common to forget to check the type of your variables in a +dynamically-typed language like JavaScript. + +Usually the consequences of assuming the wrong type is that your program crashes with an +uncaught exception. But the failure mode for forgetting to check the type of arguments to +the `Buffer` constructor is more catastrophic. + +Here's an example of a vulnerable service that takes a JSON payload and converts it to +hex: + +```js +// Take a JSON payload {str: "some string"} and convert it to hex +var server = http.createServer(function (req, res) { + var data = '' + req.setEncoding('utf8') + req.on('data', function (chunk) { + data += chunk + }) + req.on('end', function () { + var body = JSON.parse(data) + res.end(new Buffer(body.str).toString('hex')) + }) +}) + +server.listen(8080) +``` + +In this example, an http client just has to send: + +```json +{ + "str": 1000 +} +``` + +and it will get back 1,000 bytes of uninitialized memory from the server. + +This is a very serious bug. It's similar in severity to the +[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process +memory by remote attackers. + + +### Which real-world packages were vulnerable? + +#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht) + +[Mathias Buus](https://github.com/mafintosh) and I +([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages, +[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow +anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get +them to reveal 20 bytes at a time of uninitialized memory from the node.js process. + +Here's +[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8) +that fixed it. We released a new fixed version, created a +[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all +vulnerable versions on npm so users will get a warning to upgrade to a newer version. + +#### [`ws`](https://www.npmjs.com/package/ws) + +That got us wondering if there were other vulnerable packages. Sure enough, within a short +period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the +most popular WebSocket implementation in node.js. + +If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as +expected, then uninitialized server memory would be disclosed to the remote peer. + +These were the vulnerable methods: + +```js +socket.send(number) +socket.ping(number) +socket.pong(number) +``` + +Here's a vulnerable socket server with some echo functionality: + +```js +server.on('connection', function (socket) { + socket.on('message', function (message) { + message = JSON.parse(message) + if (message.type === 'echo') { + socket.send(message.data) // send back the user's message + } + }) +}) +``` + +`socket.send(number)` called on the server, will disclose server memory. + +Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue +was fixed, with a more detailed explanation. Props to +[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the +[Node Security Project disclosure](https://nodesecurity.io/advisories/67). + + +### What's the solution? + +It's important that node.js offers a fast way to get memory otherwise performance-critical +applications would needlessly get a lot slower. + +But we need a better way to *signal our intent* as programmers. **When we want +uninitialized memory, we should request it explicitly.** + +Sensitive functionality should not be packed into a developer-friendly API that loosely +accepts many different types. This type of API encourages the lazy practice of passing +variables in without checking the type very carefully. + +#### A new API: `Buffer.allocUnsafe(number)` + +The functionality of creating buffers with uninitialized memory should be part of another +API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that +frequently gets user input of all sorts of different types passed into it. + +```js +var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory! + +// Immediately overwrite the uninitialized buffer with data from another buffer +for (var i = 0; i < buf.length; i++) { + buf[i] = otherBuf[i] +} +``` + + +### How do we fix node.js core? + +We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as +`semver-major`) which defends against one case: + +```js +var str = 16 +new Buffer(str, 'utf8') +``` + +In this situation, it's implied that the programmer intended the first argument to be a +string, since they passed an encoding as a second argument. Today, node.js will allocate +uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not +what the programmer intended. + +But this is only a partial solution, since if the programmer does `new Buffer(variable)` +(without an `encoding` parameter) there's no way to know what they intended. If `variable` +is sometimes a number, then uninitialized memory will sometimes be returned. + +### What's the real long-term fix? + +We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when +we need uninitialized memory. But that would break 1000s of packages. + +~~We believe the best solution is to:~~ + +~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~ + +~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~ + +#### Update + +We now support adding three new APIs: + +- `Buffer.from(value)` - convert from any type to a buffer +- `Buffer.alloc(size)` - create a zero-filled buffer +- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size + +This solves the core problem that affected `ws` and `bittorrent-dht` which is +`Buffer(variable)` getting tricked into taking a number argument. + +This way, existing code continues working and the impact on the npm ecosystem will be +minimal. Over time, npm maintainers can migrate performance-critical code to use +`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`. + + +### Conclusion + +We think there's a serious design issue with the `Buffer` API as it exists today. It +promotes insecure software by putting high-risk functionality into a convenient API +with friendly "developer ergonomics". + +This wasn't merely a theoretical exercise because we found the issue in some of the +most popular npm packages. + +Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of +`buffer`. + +```js +var Buffer = require('safe-buffer').Buffer +``` + +Eventually, we hope that node.js core can switch to this new, safer behavior. We believe +the impact on the ecosystem would be minimal since it's not a breaking change. +Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while +older, insecure packages would magically become safe from this attack vector. + + +## links + +- [Node.js PR: buffer: throw if both length and enc are passed](https://github.com/nodejs/node/pull/4514) +- [Node Security Project disclosure for `ws`](https://nodesecurity.io/advisories/67) +- [Node Security Project disclosure for`bittorrent-dht`](https://nodesecurity.io/advisories/68) + + +## credit + +The original issues in `bittorrent-dht` +([disclosure](https://nodesecurity.io/advisories/68)) and +`ws` ([disclosure](https://nodesecurity.io/advisories/67)) were discovered by +[Mathias Buus](https://github.com/mafintosh) and +[Feross Aboukhadijeh](http://feross.org/). + +Thanks to [Adam Baldwin](https://github.com/evilpacket) for helping disclose these issues +and for his work running the [Node Security Project](https://nodesecurity.io/). + +Thanks to [John Hiesey](https://github.com/jhiesey) for proofreading this README and +auditing the code. + + +## license + +MIT.

Try [serve-static](https://www.npmjs.org/package/serve-static). + +## Installation + +This is a [Node.js](https://nodejs.org/en/) module available through the +[npm registry](https://www.npmjs.com/).

The `req` is +the Node.js HTTP request and the `path` is a urlencoded path to send (urlencoded, +not the actual file-system path). + +#### Options + +##### acceptRanges + +Enable or disable accepting ranged requests, defaults to true. +Disabling this will not send `Accept-Ranges` and ignore the contents +of the `Range` request header. + +##### cacheControl + +Enable or disable setting `Cache-Control` response header, defaults to +true. Disabling this will ignore the `immutable` and `maxAge` options. + +##### dotfiles + +Set how "dotfiles" are treated when encountered. A dotfile is a file +or directory that begins with a dot ("."). Note this check is done on +the path itself without checking if the path actually exists on the +disk. If `root` is specified, only the dotfiles above the root are +checked (i.e. the root itself can be within a dotfile when when set +to "deny"). + + - `'allow'` No special treatment for dotfiles. + - `'deny'` Send a 403 for any request for a dotfile. + - `'ignore'` Pretend like the dotfile does not exist and 404. + +The default value is _similar_ to `'ignore'`, with the exception that +this default will not ignore the files within a directory that begins +with a dot, for backward-compatibility. + +##### end + +Byte offset at which the stream ends, defaults to the length of the file +minus 1. The end is inclusive in the stream, meaning `end: 3` will include +the 4th byte in the stream. + +##### etag + +Enable or disable etag generation, defaults to true. + +##### extensions + +If a given file doesn't exist, try appending one of the given extensions, +in the given order. By default, this is disabled (set to `false`). An +example value that will serve extension-less HTML files: `['html', 'htm']`. +This is skipped if the requested file already has an extension. + +##### immutable + +Enable or diable the `immutable` directive in the `Cache-Control` response +header, defaults to `false`. If set to `true`, the `maxAge` option should +also be specified to enable caching. The `immutable` directive will prevent +supported clients from making conditional requests during the life of the +`maxAge` option to check if the file has changed. + +##### index + +By default send supports "index.html" files, to disable this +set `false` or to supply a new index pass a string or an array +in preferred order. + +##### lastModified + +Enable or disable `Last-Modified` header, defaults to true. Uses the file +system's last modified value. + +##### maxAge + +Provide a max-age in milliseconds for http caching, defaults to 0. +This can also be a string accepted by the +[ms](https://www.npmjs.org/package/ms#readme) module. + +##### root + +Serve files relative to `path`. + +##### start + +Byte offset at which the stream starts, defaults to 0. The start is inclusive, +meaning `start: 2` will include the 3rd byte in the stream. + +#### Events + +The `SendStream` is an event emitter and will emit the following events: + + - `error` an error occurred `(err)` + - `directory` a directory was requested `(res, path)` + - `file` a file was requested `(path, stat)` + - `headers` the headers are about to be set on a file `(res, path, stat)` + - `stream` file streaming has started `(stream)` + - `end` streaming has completed + +#### .pipe + +The `pipe` method is used to pipe the response into the Node.js HTTP response +object, typically `send(req, path, options).pipe(res)`. + +### .mime + +The `mime` export is the global instance of of the +[`mime` npm module](https://www.npmjs.com/package/mime). + +This is used to configure the MIME types that are associated with file extensions +as well as other options for how to resolve the MIME type of a file (like the +default type to use for an unknown file extension). + +## Error-handling + +By default when no `error` listeners are present an automatic response will be +made, otherwise you have full control over the response, aka you may show a 5xx +page etc. + +## Caching + +It does _not_ perform internal caching, you should use a reverse proxy cache +such as Varnish for this, or those fancy things called CDNs.

The file to serve will be determined by combining `req.url` +with the provided root directory. When a file is not found, instead of +sending a 404 response, this module will instead call `next()` to move on +to the next middleware, allowing for stacking and fall-backs. + +#### Options + +##### acceptRanges + +Enable or disable accepting ranged requests, defaults to true. +Disabling this will not send `Accept-Ranges` and ignore the contents +of the `Range` request header. + +##### cacheControl + +Enable or disable setting `Cache-Control` response header, defaults to +true. Disabling this will ignore the `immutable` and `maxAge` options. + +##### dotfiles + + Set how "dotfiles" are treated when encountered. A dotfile is a file +or directory that begins with a dot ("."). Note this check is done on +the path itself without checking if the path actually exists on the +disk. If `root` is specified, only the dotfiles above the root are +checked (i.e. the root itself can be within a dotfile when set +to "deny"). + + - `'allow'` No special treatment for dotfiles. + - `'deny'` Deny a request for a dotfile and 403/`next()`. + - `'ignore'` Pretend like the dotfile does not exist and 404/`next()`. + +The default value is similar to `'ignore'`, with the exception that this +default will not ignore the files within a directory that begins with a dot. + +##### etag + +Enable or disable etag generation, defaults to true. + +##### extensions + +Set file extension fallbacks. When set, if a file is not found, the given +extensions will be added to the file name and search for. The first that +exists will be served. Example: `['html', 'htm']`. + +The default value is `false`. + +##### fallthrough + +Set the middleware to have client errors fall-through as just unhandled +requests, otherwise forward a client error. The difference is that client +errors like a bad request or a request to a non-existent file will cause +this middleware to simply `next()` to your next middleware when this value +is `true`. When this value is `false`, these errors (even 404s), will invoke +`next(err)`. + +Typically `true` is desired such that multiple physical directories can be +mapped to the same web address or for routes to fill in non-existent files. + +The value `false` can be used if this middleware is mounted at a path that +is designed to be strictly a single file system directory, which allows for +short-circuiting 404s for less overhead. This middleware will also reply to +all methods. + +The default value is `true`. + +##### immutable + +Enable or disable the `immutable` directive in the `Cache-Control` response +header, defaults to `false`. If set to `true`, the `maxAge` option should +also be specified to enable caching. The `immutable` directive will prevent +supported clients from making conditional requests during the life of the +`maxAge` option to check if the file has changed. + +##### index + +By default this module will send "index.html" files in response to a request +on a directory. To disable this set `false` or to supply a new index pass a +string or an array in preferred order. + +##### lastModified + +Enable or disable `Last-Modified` header, defaults to true. Uses the file +system's last modified value. + +##### maxAge + +Provide a max-age in milliseconds for http caching, defaults to 0. This +can also be a string accepted by the [ms](https://www.npmjs.org/package/ms#readme) +module. + +##### redirect + +Redirect to trailing "/" when the pathname is a dir. Defaults to `true`. + +##### setHeaders + +Function to set custom headers on response. Alterations to the headers need to +occur synchronously. The function is called as `fn(res, path, stat)`, where +the arguments are: + + - `res` the response object + - `path` the file path that is being sent + - `stat` the stat object of the file that is being sent + +## Examples + +### Serve files with vanilla node.js http server + +```js +var finalhandler = require('finalhandler') +var http = require('http') +var serveStatic = require('serve-static') + +// Serve up public/ftp folder +var serve = serveStatic('public/ftp', {'index': ['index.html', 'index.htm']}) + +// Create server +var server = http.createServer(function onRequest (req, res) { + serve(req, res, finalhandler(req, res)) +}) + +// Listen +server.listen(3000) +``` + +### Serve all files as downloads + +```js +var contentDisposition = require('content-disposition') +var finalhandler = require('finalhandler') +var http = require('http') +var serveStatic = require('serve-static') + +// Serve up public/ftp folder +var serve = serveStatic('public/ftp', { + 'index': false, + 'setHeaders': setHeaders +}) + +// Set header to force download +function setHeaders (res, path) { + res.setHeader('Content-Disposition', contentDisposition(path)) +} + +// Create server +var server = http.createServer(function onRequest (req, res) { + serve(req, res, finalhandler(req, res)) +}) + +// Listen +server.listen(3000) +``` + +### Serving using express + +#### Simple + +This is a simple example of using Express. + +```js +var express = require('express') +var serveStatic = require('serve-static') + +var app = express() + +app.use(serveStatic('public/ftp', {'index': ['default.html', 'default.htm']})) +app.listen(3000) +``` + +#### Multiple roots + +This example shows a simple way to search through multiple directories. +Files are look for in `public-optimized/` first, then `public/` second as +a fallback. + +```js +var express = require('express') +var path = require('path') +var serveStatic = require('serve-static') + +var app = express() + +app.use(serveStatic(path.join(__dirname, 'public-optimized'))) +app.use(serveStatic(path.join(__dirname, 'public'))) +app.listen(3000) +``` + +#### Different settings for paths + +This example shows how to set a different max age depending on the served +file type.
