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.

Commands that return a single line reply return JavaScript Strings, +integer replies return JavaScript Numbers, "bulk" replies return node Buffers, and "multi bulk" replies return a +JavaScript Array of node Buffers. `HGETALL` returns an Object with Buffers keyed by the hash keys. + +# API + +## Connection Events + +`client` will emit some events about the state of the connection to the Redis server. + +### "ready" + +`client` will emit `ready` a connection is established to the Redis server and the server reports +that it is ready to receive commands. Commands issued before the `ready` event are queued, +then replayed just before this event is emitted. + +### "connect" + +`client` will emit `connect` at the same time as it emits `ready` unless `client.options.no_ready_check` +is set. If this options is set, `connect` will be emitted when the stream is connected, and then +you are free to try to send commands. + +### "error" + +`client` will emit `error` when encountering an error connecting to the Redis server. + +Note that "error" is a special event type in node. If there are no listeners for an +"error" event, node will exit. This is usually what you want, but it can lead to some +cryptic error messages like this: + + mjr:~/work/node_redis (master)$ node example.js + + node.js:50 + throw e; + ^ + Error: ECONNREFUSED, Connection refused + at IOWatcher.callback (net:870:22) + at node.js:607:9 + +Not very useful in diagnosing the problem, but if your program isn't ready to handle this, +it is probably the right thing to just exit. + +`client` will also emit `error` if an exception is thrown inside of `node_redis` for whatever reason. +It would be nice to distinguish these two cases. + +### "end" + +`client` will emit `end` when an established Redis server connection has closed. + +### "drain" + +`client` will emit `drain` when the TCP connection to the Redis server has been buffering, but is now +writable. This event can be used to stream commands in to Redis and adapt to backpressure. Right now, +you need to check `client.command_queue.length` to decide when to reduce your send rate. Then you can +resume sending when you get `drain`. + +### "idle" + +`client` will emit `idle` when there are no outstanding commands that are awaiting a response. + +## redis.createClient() + +### overloading +* redis.createClient() = redis.createClient(6379, '127.0.0.1', {}) +* redis.createClient(options) = redis.createClient(6379, '127.0.0.1', options) +* redis.createClient(unix_socket, options) +* redis.createClient(port, host, options) + +If you have `redis-server` running on the same computer as node, then the defaults for +port and host are probably fine. `options` in an object with the following possible properties: + +* `parser`: which Redis protocol reply parser to use. Defaults to `hiredis` if that module is installed. +This may also be set to `javascript`. +* `return_buffers`: defaults to `false`. If set to `true`, then all replies will be sent to callbacks as node Buffer +objects instead of JavaScript Strings. +* `detect_buffers`: default to `false`. If set to `true`, then replies will be sent to callbacks as node Buffer objects +if any of the input arguments to the original command were Buffer objects. +This option lets you switch between Buffers and Strings on a per-command basis, whereas `return_buffers` applies to +every command on a client. +* `socket_nodelay`: defaults to `true`. Whether to call setNoDelay() on the TCP stream, which disables the +Nagle algorithm on the underlying socket. Setting this option to `false` can result in additional throughput at the +cost of more latency. Most applications will want this set to `true`. +* `socket_keepalive` defaults to `true`. Whether the keep-alive functionality is enabled on the underlying socket. +* `no_ready_check`: defaults to `false`. When a connection is established to the Redis server, the server might still +be loading the database from disk. While loading, the server not respond to any commands. To work around this, +`node_redis` has a "ready check" which sends the `INFO` command to the server. The response from the `INFO` command +indicates whether the server is ready for more commands. When ready, `node_redis` emits a `ready` event. +Setting `no_ready_check` to `true` will inhibit this check. +* `enable_offline_queue`: defaults to `true`. By default, if there is no active +connection to the redis server, commands are added to a queue and are executed +once the connection has been established. Setting `enable_offline_queue` to +`false` will disable this feature and the callback will be execute immediately +with an error, or an error will be thrown if no callback is specified. +* `retry_max_delay`: defaults to `null`. By default every time the client tries to connect and fails time before +reconnection (delay) almost doubles. This delay normally grows infinitely, but setting `retry_max_delay` limits delay +to maximum value, provided in milliseconds. +* `connect_timeout` defaults to `false`. By default client will try reconnecting until connected. Setting `connect_timeout` +limits total time for client to reconnect. Value is provided in milliseconds and is counted once the disconnect occured. +* `max_attempts` defaults to `null`. By default client will try reconnecting until connected. Setting `max_attempts` +limits total amount of reconnects. +* `auth_pass` defaults to `null`. By default client will try connecting without auth. If set, client will run redis auth command on connect. +* `family` defaults to `IPv4`. The client connects in IPv4 if not specified or if the DNS resolution returns an IPv4 address. +You can force an IPv6 if you set the family to 'IPv6'. See nodejs net or dns modules how to use the family type. + +```js + var redis = require("redis"), + client = redis.createClient({detect_buffers: true}); + + client.set("foo_rand000000000000", "OK"); + + // This will return a JavaScript String + client.get("foo_rand000000000000", function (err, reply) { + console.log(reply.toString()); // Will print `OK` + }); + + // This will return a Buffer since original key is specified as a Buffer + client.get(new Buffer("foo_rand000000000000"), function (err, reply) { + console.log(reply.toString()); // Will print `` + }); + client.end(); +``` + +`createClient()` returns a `RedisClient` object that is named `client` in all of the examples here. + + +## client.auth(password, callback) + +When connecting to Redis servers that require authentication, the `AUTH` command must be sent as the +first command after connecting. This can be tricky to coordinate with reconnections, the ready check, +etc. To make this easier, `client.auth()` stashes `password` and will send it after each connection, +including reconnections. `callback` is invoked only once, after the response to the very first +`AUTH` command sent. +NOTE: Your call to `client.auth()` should not be inside the ready handler. If +you are doing this wrong, `client` will emit an error that looks +something like this `Error: Ready check failed: ERR operation not permitted`. + +## client.end() + +Forcibly close the connection to the Redis server. Note that this does not wait until all replies have been parsed. +If you want to exit cleanly, call `client.quit()` to send the `QUIT` command after you have handled all replies. + +This example closes the connection to the Redis server before the replies have been read. You probably don't +want to do this: + +```js + var redis = require("redis"), + client = redis.createClient(); + + client.set("foo_rand000000000000", "some fantastic value"); + client.get("foo_rand000000000000", function (err, reply) { + console.log(reply.toString()); + }); + client.end(); +``` + +`client.end()` is useful for timeout cases where something is stuck or taking too long and you want +to start over. + +## client.unref() + +Call `unref()` on the underlying socket connection to the Redis server, allowing the program to exit once no more commands are pending. + +This is an **experimental** feature, and only supports a subset of the Redis protocol. Any commands where client state is saved on the Redis server, e.g. `*SUBSCRIBE` or the blocking `BL*` commands will *NOT* work with `.unref()`. + +```js +var redis = require("redis") +var client = redis.createClient() + +/* + Calling unref() will allow this program to exit immediately after the get command finishes. Otherwise the client would hang as long as the client-server connection is alive. +*/ +client.unref() +client.get("foo", function (err, value){ + if (err) throw(err) + console.log(value) +}) +``` + +## Friendlier hash commands + +Most Redis commands take a single String or an Array of Strings as arguments, and replies are sent back as a single String or an Array of Strings. +When dealing with hash values, there are a couple of useful exceptions to this. + +### client.hgetall(hash) + +The reply from an HGETALL command will be converted into a JavaScript Object by `node_redis`. That way you can interact +with the responses using JavaScript syntax. + +Example: + + client.hmset("hosts", "mjr", "1", "another", "23", "home", "1234"); + client.hgetall("hosts", function (err, obj) { + console.dir(obj); + }); + +Output: + + { mjr: '1', another: '23', home: '1234' } + +### client.hmset(hash, obj, [callback]) + +Multiple values in a hash can be set by supplying an object: + + client.HMSET(key2, { + "0123456789": "abcdefghij", // NOTE: key and value will be coerced to strings + "some manner of key": "a type of value" + }); + +The properties and values of this Object will be set as keys and values in the Redis hash. + +### client.hmset(hash, key1, val1, ... keyn, valn, [callback]) + +Multiple values may also be set by supplying a list: + + client.HMSET(key1, "0123456789", "abcdefghij", "some manner of key", "a type of value"); + + +## Publish / Subscribe + +Here is a simple example of the API for publish / subscribe. This program opens two +client connections, subscribes to a channel on one of them, and publishes to that +channel on the other: + +```js + var redis = require("redis"), + client1 = redis.createClient(), client2 = redis.createClient(), + msg_count = 0; + + client1.on("subscribe", function (channel, count) { + client2.publish("a nice channel", "I am sending a message."); + client2.publish("a nice channel", "I am sending a second message."); + client2.publish("a nice channel", "I am sending my last message."); + }); + + client1.on("message", function (channel, message) { + console.log("client1 channel " + channel + ": " + message); + msg_count += 1; + if (msg_count === 3) { + client1.unsubscribe(); + client1.end(); + client2.end(); + } + }); + + client1.incr("did a thing"); + client1.subscribe("a nice channel"); +``` + +When a client issues a `SUBSCRIBE` or `PSUBSCRIBE`, that connection is put into a "subscriber" mode. +At that point, only commands that modify the subscription set are valid. When the subscription +set is empty, the connection is put back into regular mode. + +If you need to send regular commands to Redis while in subscriber mode, just open another connection. + +## Subscriber Events + +If a client has subscriptions active, it may emit these events: + +### "message" (channel, message) + +Client will emit `message` for every message received that matches an active subscription. +Listeners are passed the channel name as `channel` and the message Buffer as `message`. + +### "pmessage" (pattern, channel, message) + +Client will emit `pmessage` for every message received that matches an active subscription pattern. +Listeners are passed the original pattern used with `PSUBSCRIBE` as `pattern`, the sending channel +name as `channel`, and the message Buffer as `message`. + +### "subscribe" (channel, count) + +Client will emit `subscribe` in response to a `SUBSCRIBE` command. Listeners are passed the +channel name as `channel` and the new count of subscriptions for this client as `count`. + +### "psubscribe" (pattern, count) + +Client will emit `psubscribe` in response to a `PSUBSCRIBE` command. Listeners are passed the +original pattern as `pattern`, and the new count of subscriptions for this client as `count`. + +### "unsubscribe" (channel, count) + +Client will emit `unsubscribe` in response to a `UNSUBSCRIBE` command. Listeners are passed the +channel name as `channel` and the new count of subscriptions for this client as `count`. When +`count` is 0, this client has left subscriber mode and no more subscriber events will be emitted. + +### "punsubscribe" (pattern, count) + +Client will emit `punsubscribe` in response to a `PUNSUBSCRIBE` command. Listeners are passed the +channel name as `channel` and the new count of subscriptions for this client as `count`. When +`count` is 0, this client has left subscriber mode and no more subscriber events will be emitted. + +## client.multi([commands]) + +`MULTI` commands are queued up until an `EXEC` is issued, and then all commands are run atomically by +Redis. The interface in `node_redis` is to return an individual `Multi` object by calling `client.multi()`. + +```js + var redis = require("./index"), + client = redis.createClient(), set_size = 20; + + client.sadd("bigset", "a member"); + client.sadd("bigset", "another member"); + + while (set_size > 0) { + client.sadd("bigset", "member " + set_size); + set_size -= 1; + } + + // multi chain with an individual callback + client.multi() + .scard("bigset") + .smembers("bigset") + .keys("*", function (err, replies) { + // NOTE: code in this callback is NOT atomic + // this only happens after the the .exec call finishes. + client.mget(replies, redis.print); + }) + .dbsize() + .exec(function (err, replies) { + console.log("MULTI got " + replies.length + " replies"); + replies.forEach(function (reply, index) { + console.log("Reply " + index + ": " + reply.toString()); + }); + }); +``` + +### Multi.exec( callback ) + +`client.multi()` is a constructor that returns a `Multi` object. `Multi` objects share all of the +same command methods as `client` objects do. Commands are queued up inside the `Multi` object +until `Multi.exec()` is invoked. + +The `callback` of `.exec()` will get invoked with two arguments: + +* `err` **type:** `null | Array` err is either null or an array of Error Objects corresponding the the sequence the commands where chained. The last item of the array will always be an `EXECABORT` type of error originating from the `.exec()` itself. +* `results` **type:** `null | Array` results is an array of responses corresponding the the sequence the commands where chained. + +You can either chain together `MULTI` commands as in the above example, or you can queue individual +commands while still sending regular client command as in this example: + +```js + var redis = require("redis"), + client = redis.createClient(), multi; + + // start a separate multi command queue + multi = client.multi(); + multi.incr("incr thing", redis.print); + multi.incr("incr other thing", redis.print); + + // runs immediately + client.mset("incr thing", 100, "incr other thing", 1, redis.print); + + // drains multi queue and runs atomically + multi.exec(function (err, replies) { + console.log(replies); // 101, 2 + }); + + // you can re-run the same transaction if you like + multi.exec(function (err, replies) { + console.log(replies); // 102, 3 + client.quit(); + }); +``` + +In addition to adding commands to the `MULTI` queue individually, you can also pass an array +of commands and arguments to the constructor: + +```js + var redis = require("redis"), + client = redis.createClient(), multi; + + client.multi([ + ["mget", "multifoo", "multibar", redis.print], + ["incr", "multifoo"], + ["incr", "multibar"] + ]).exec(function (err, replies) { + console.log(replies); + }); +``` + + +## Monitor mode + +Redis supports the `MONITOR` command, which lets you see all commands received by the Redis server +across all client connections, including from other client libraries and other computers. + +After you send the `MONITOR` command, no other commands are valid on that connection. `node_redis` +will emit a `monitor` event for every new monitor message that comes across. The callback for the +`monitor` event takes a timestamp from the Redis server and an array of command arguments. + +Here is a simple example: + +```js + var client = require("redis").createClient(), + util = require("util"); + + client.monitor(function (err, res) { + console.log("Entering monitoring mode."); + }); + + client.on("monitor", function (time, args) { + console.log(time + ": " + util.inspect(args)); + }); +``` + +# Extras + +Some other things you might like to know about. + +## client.server_info + +After the ready probe completes, the results from the INFO command are saved in the `client.server_info` +object. + +The `versions` key contains an array of the elements of the version string for easy comparison. + + > client.server_info.redis_version + '2.3.0' + > client.server_info.versions + [ 2, 3, 0 ] + +## redis.print() + +A handy callback function for displaying return values when testing. Example: + +```js + var redis = require("redis"), + client = redis.createClient(); + + client.on("connect", function () { + client.set("foo_rand000000000000", "some fantastic value", redis.print); + client.get("foo_rand000000000000", redis.print); + }); +``` + +This will print: + + Reply: OK + Reply: some fantastic value + +Note that this program will not exit cleanly because the client is still connected. + +## redis.debug_mode + +Boolean to enable debug mode and protocol tracing. + +```js + var redis = require("redis"), + client = redis.createClient(); + + redis.debug_mode = true; + + client.on("connect", function () { + client.set("foo_rand000000000000", "some fantastic value"); + }); +``` + +This will display: + + mjr:~/work/node_redis (master)$ node ~/example.js + send command: *3 + $3 + SET + $20 + foo_rand000000000000 + $20 + some fantastic value + + on_data: +OK + +`send command` is data sent into Redis and `on_data` is data received from Redis. + +## Multi-word commands + +To execute redis multi-word commands like `SCRIPT LOAD` or `CLIENT LIST` pass +the second word as first parameter: + + client.script('load', 'return 1'); + client.multi().script('load', 'return 1').exec(...); + client.multi([['script', 'load', 'return 1']]).exec(...); + +## client.send_command(command_name, args, callback) + +Used internally to send commands to Redis. For convenience, nearly all commands that are published on the Redis +Wiki have been added to the `client` object. However, if I missed any, or if new commands are introduced before +this library is updated, you can use `send_command()` to send arbitrary commands to Redis. + +All commands are sent as multi-bulk commands. `args` can either be an Array of arguments, or omitted. + +## client.connected + +Boolean tracking the state of the connection to the Redis server. + +## client.command_queue.length + +The number of commands that have been sent to the Redis server but not yet replied to. You can use this to +enforce some kind of maximum queue depth for commands while connected. + +Don't mess with `client.command_queue` though unless you really know what you are doing. + +## client.offline_queue.length + +The number of commands that have been queued up for a future connection. You can use this to enforce +some kind of maximum queue depth for pre-connection commands. + +## client.retry_delay + +Current delay in milliseconds before a connection retry will be attempted. This starts at `250`. + +## client.retry_backoff + +Multiplier for future retry timeouts. This should be larger than 1 to add more time between retries. +Defaults to 1.7. The default initial connection retry is 250, so the second retry will be 425, followed by 723.5, etc. + +### Commands with Optional and Keyword arguments + +This applies to anything that uses an optional `[WITHSCORES]` or `[LIMIT offset count]` in the [redis.io/commands](http://redis.io/commands) documentation. + +Example: +```js +var args = [ 'myzset', 1, 'one', 2, 'two', 3, 'three', 99, 'ninety-nine' ]; +client.zadd(args, function (err, response) { + if (err) throw err; + console.log('added '+response+' items.'); + + // -Infinity and +Infinity also work + var args1 = [ 'myzset', '+inf', '-inf' ]; + client.zrevrangebyscore(args1, function (err, response) { + if (err) throw err; + console.log('example1', response); + // write your code here + }); + + var max = 3, min = 1, offset = 1, count = 2; + var args2 = [ 'myzset', max, min, 'WITHSCORES', 'LIMIT', offset, count ]; + client.zrevrangebyscore(args2, function (err, response) { + if (err) throw err; + console.log('example2', response); + // write your code here + }); +}); +``` + +## TODO + +Better tests for auth, disconnect/reconnect, and all combinations thereof. + +Stream large set/get values into and out of Redis.
