BREAKING CHANGES

Apollo Server v5 has very few breaking API changes. It is a small upgrade focused largely on adjusting which versions of Node.js and Express are supported.

Read our migration guide for more details on how to update your app.

  • Dropped support for Node.js v14, v16, and v18, which are no longer under long-term support from the Node.js Foundation. Apollo Server 5 supports Node.js v20 and later; v24 is recommended. Ensure you are on a non-EOL version of Node.js before upgrading Apollo Server.
  • Dropped support for versions of the graphql library older than v16.11.0. (Apollo Server 4 supports graphql v16.6.0 or later.) Upgrade graphql before upgrading Apollo Server.
  • Express integration requires a separate package. In Apollo Server 4, you could import the Express 4 middleware from @apollo/server/express4, or you could import it from the separate package @as-integrations/express4. In Apollo Server 5, you must import it from the separate package. You can migrate your server to the new package before upgrading to Apollo Server 5. (You can also use @as-integrations/express5 for a middleware that works with Express 5.)
  • Usage Reporting, Schema Reporting, and Subscription Callback plugins now use the Node.js built-in fetch implementation for HTTP requests by default, instead of the node-fetch npm package. If your server uses an HTTP proxy to make HTTP requests, you need to configure it in a slightly different way. See the migration guide for details.
  • The server started with startStandaloneServer no longer uses Express. This is mostly invisible, but it does set slightly fewer headers. If you rely on the fact that this server is based on Express, you should explicitly use the Express middleware.
  • The experimental support for incremental delivery directives @defer and @stream (which requires using a pre-release version of graphql v17) now explicitly only works with version 17.0.0-alpha.2 of graphql. Note that this supports the same incremental delivery protocol implemented by Apollo Server 4, which is not the same protocol in the latest alpha version of graphql. As this support is experimental, we may switch over from "only alpha.2 is supported" to "only a newer alpha or final release is supported, with a different protocol" during the lifetime of Apollo Server 5.
  • Apollo Server is now compiled by the TypeScript compiler targeting the ES2023 standard rather than the ES2020 standard.
  • Apollo Server 5 responds to requests with variable coercion errors (eg, if a number is passed in the variables map for a variable declared in the operation as a String) with a 400 status code, indicating a client error. This is also the behavior of Apollo Server 3. Apollo Server 4 mistakenly responds to these requests with a 200 status code by default; we recommended the use of the status400ForVariableCoercionErrors: true option to restore the intended behavior. That option now defaults to true.
  • The unsafe precomputedNonce option to landing page plugins (which was only non-deprecated for 8 days) has been removed.
Patch Changes

There are a few other small changes in v5:

  • #​8076 5b26558 Thanks @​valters! - Fix some error logs to properly call logger.error or logger.warn with this set. This fixes errors or crashes from logger implementations that expect this to be set properly in their methods.

  • #​7515 100233a Thanks @​trevor-scheer! - ApolloServerPluginSubscriptionCallback now takes a fetcher argument, like the usage and schema reporting plugins. The default value is Node's built-in fetch.

  • Updated dependencies [100233a]:

  • #​8054 89e3f84 Thanks @​clenfest! - Adds a new graphql-js validation rule to reject operations that recursively request selections above a specified maximum, which is disabled by default. Use configuration option maxRecursiveSelections=true to enable with a maximum of 10,000,000, or maxRecursiveSelections=<number> for a custom maximum. Enabling this validation can help avoid performance issues with configured validation rules or plugins.

v4.11.1

Compare Source

Patch Changes
  • #​7952 bb81b2c Thanks @​glasser! - Upgrade dependencies so that automated scans don't detect a vulnerability.

    @apollo/server depends on express which depends on cookie. Versions of express older than v4.21.1 depend on a version of cookie vulnerable to CVE-2024-47764. Users of older express versions who call res.cookie() or res.clearCookie() may be vulnerable to this issue.

    However, Apollo Server does not call this function directly, and it does not expose any object to user code that allows TypeScript users to call this function without an unsafe cast.

    The only way that this direct dependency can cause a vulnerability for users of Apollo Server is if you call startStandaloneServer with a context function that calls Express-specific methods such as res.cookie() or res.clearCookies() on the response object, which is a violation of the TypeScript types provided by startStandaloneServer (which only promise that the response object is a core Node.js http.ServerResponse rather than the Express-specific subclass). So this vulnerability can only affect Apollo Server users who use unsafe JavaScript or unsafe as typecasts in TypeScript.

    However, this upgrade will at least prevent vulnerability scanners from alerting you to this dependency, and we encourage all Express users to upgrade their project's own express dependency to v4.21.1 or newer.

v4.11.0

Compare Source

Minor Changes
  • #​7916 4686454 Thanks @​andrewmcgivery! - Add hideSchemaDetailsFromClientErrors option to ApolloServer to allow hiding 'did you mean' suggestions from validation errors.

    Even with introspection disabled, it is possible to "fuzzy test" a graph manually or with automated tools to try to determine the shape of your schema. This is accomplished by taking advantage of the default behavior where a misspelt field in an operation
    will be met with a validation error that includes a helpful "did you mean" as part of the error text.

    For example, with this option set to true, an error would read Cannot query field "help" on type "Query". whereas with this option set to false it would read Cannot query field "help" on type "Query". Did you mean "hello"?.

    We recommend enabling this option in production to avoid leaking information about your schema to malicious actors.

    To enable, set this option to true in your ApolloServer options:

    const server = new ApolloServer({
      typeDefs,
      resolvers,
      hideSchemaDetailsFromClientErrors: true,
    });

Patch Changes
  • #​7871 18a3827 Thanks @​tninesling! - Subscription heartbeats are initialized prior to awaiting subscribe(). This allows long-running setup to happen in the returned Promise without the subscription being terminated prior to resolution.

v4.10.3

Patch Changes
  • #​7866 5f335a5 Thanks @​tninesling! - Catch errors thrown by subscription generators, and gracefully clean up the subscription instead of crashing.

v4.10.2

Patch Changes
  • #​7849 c7e514c Thanks @​TylerBloom! - In the subscription callback server plugin, terminating a subscription now immediately closes the internal async generator. This avoids that generator existing after termination and until the next message is received.

v4.10.1

Patch Changes
  • #​7843 72f568e Thanks @​bscherlein! - Improves timing of the willResolveField end hook on fields which return Promises resolving to Arrays. This makes the use of the setCacheHint method more reliable.

v4.10.0

Compare Source

Minor Changes
  • #​7786 869ec98 Thanks @​ganemone! - Restore missing v1 skipValidation option as dangerouslyDisableValidation. Note that enabling this option exposes your server to potential security and unexpected runtime issues. Apollo will not support issues that arise as a result of using this option.

  • #​7803 e9a0d6e Thanks @​favna! - allow stringifyResult to return a Promise<string>

    Users who implemented the stringifyResult hook can now expect error responses to be formatted with the hook as well. Please take care when updating to this version to ensure this is the desired behavior, or implement the desired behavior accordingly in your stringifyResult hook. This was considered a non-breaking change as we consider that it was an oversight in the original PR that introduced stringifyResult hook.

Patch Changes
  • #​7747 ddce036e1 Thanks @​trevor-scheer! - The minimum version of graphql officially supported by Apollo Server 4 as a peer dependency, v16.6.0, contains a serious bug that can crash your Node server. This bug is fixed in the immediate next version, [email protected], and we strongly encourage you to upgrade your installation of graphql to at least v16.7.0 to avoid this bug. (For backwards compatibility reasons, we cannot change Apollo Server 4's minimum peer dependency, but will change it when we release Apollo Server 5.)

    Apollo Server 4 contained a particular line of code that makes triggering this crashing bug much more likely. This line was already removed in Apollo Server v3.8.2 (see #​6398) but the fix was accidentally not included in Apollo Server 4. We are now including this change in Apollo Server 4, which will reduce the likelihood of hitting this crashing bug for users of graphql v16.6.0. That said, taking this @apollo/server upgrade does not prevent this bug from being triggered in other ways, and the real fix to this crashing bug is to upgrade graphql.

v4.9.3

Compare Source

Patch Changes
  • a1c725eaf Thanks @​trevor-scheer! - Ensure API keys are valid header values on startup

    Apollo Server previously performed no sanitization or validation of API keys on startup. In the case that an API key was provided which contained characters that are invalid as header values, Apollo Server could inadvertently log the API key in cleartext.

    This only affected users who:

    • Provide an API key with characters that are invalid as header values
    • Use either schema or usage reporting
    • Use the default fetcher provided by Apollo Server or configure their own node-fetch fetcher

    Apollo Server now trims whitespace from API keys and validates that they are valid header values. If an invalid API key is provided, Apollo Server will throw an error on startup.

    For more details, see the security advisory:
    GHSA-j5g3-5c8r-7qfx

v4.9.2

Patch Changes
  • #​7699 62e7d940d Thanks @​trevor-scheer! - Fix error path attachment for list items

    Previously, when errors occurred while resolving a list item, the trace builder would fail to place the error at the correct path and just default to the root node with a warning message:

    Could not find node with path x.y.1, defaulting to put errors on root node.

    This change places these errors at their correct paths and removes the log.

Minor Changes
  • #​7617 4ff81ca50 Thanks @​trevor-scheer! - Introduce new ApolloServerPluginSubscriptionCallback plugin. This plugin implements the subscription callback protocol which is used by Apollo Router. This feature implements subscriptions over HTTP via a callback URL which Apollo Router registers with Apollo Server. This feature is currently in preview and is subject to change.

    You can enable callback subscriptions like so:

    import { ApolloServerPluginSubscriptionCallback } from '@&#8203;apollo/server/plugin/subscriptionCallback';
    import { ApolloServer } from '@&#8203;apollo/server';
    
    const server = new ApolloServer({
      // ...
      plugins: [ApolloServerPluginSubscriptionCallback()],
    });

    Note that there is currently no tracing or metrics mechanism in place for callback subscriptions. Additionally, this plugin "intercepts" callback subscription requests and bypasses some of Apollo Server's internals. The result of this is that certain plugin hooks (notably executionDidStart and willResolveField) will not be called when handling callback subscription requests or when sending subscription events.

    For more information on the subscription callback protocol, visit the docs:

Patch Changes
  • 0adaf80d1 Thanks @​trevor-scheer! - Address Content Security Policy issues

    The previous implementation of CSP nonces within the landing pages did not take full advantage of the security benefit of using them. Nonces should only be used once per request, whereas Apollo Server was generating one nonce and reusing it for the lifetime of the instance. The reuse of nonces degrades the security benefit of using them but does not pose a security risk on its own. The CSP provides a defense-in-depth measure against a potential XSS, so in the absence of a known XSS vulnerability there is likely no risk to the user.

    The mentioned fix also coincidentally addresses an issue with using crypto functions on startup within Cloudflare Workers. Crypto functions are now called during requests only, which resolves the error that Cloudflare Workers were facing. A recent change introduced a precomputedNonce configuration option to mitigate this issue, but it was an incorrect approach given the nature of CSP nonces. This configuration option is now deprecated and should not be used for any reason since it suffers from the previously mentioned issue of reusing nonces.

    Additionally, this change adds other applicable CSPs for the scripts, styles, images, manifest, and iframes that the landing pages load.

    A final consequence of this change is an extension of the renderLandingPage plugin hook. This hook can now return an object with an html property which returns a Promise<string> in addition to a string (which was the only option before).

Major Changes
  • Drop support for Node.JS v14, v16, and v20.

  • The integration test suite no longer uses lib: ["dom"] to tell TypeScript to assume DOM-related symbols are in the global namespace. If your integration library's test suite relied on this behavior, you may need to add lib: ["dom"] to the compilerOptions section of your test suite's tsconfig.json.

Patch Changes
  • #​8070 0dee3c9 Thanks @​glasser! - Provide dual-build CJS and ESM for @apollo/server-integration-testsuite.

    We previously provided only a CJS build of this package, unlike @apollo/server
    itself and the other helper packages that come with it. We may make all of
    Apollo Server ESM-only in AS5; this is a step in that direction. Specifically,
    only providing this package for CJS makes it challenging to run the tests in
    ts-jest in some ESM-only setups, because the copy of @apollo/server fetched
    directly in your ESM-based test may differ from the copy fetched indirectly via
    @apollo/server-integration-testsuite, causing the "lockstep versioning" test
    to fail.

Hi @arimus 👋🏼 Thanks for maintaining this package!

I'm upgrading to @apollo/server v5 and hit a version mismatch here. Is v5 support on the roadmap? I noticed activity has been quiet, so I'm checking whether someone’s tracking this.

If no one is, I'm happy to help test or open a PR. Thanks again for all your work! 🙏🏼
