: Studio usage reporting now reports "referenced operations" for fields in addition to "field executions", which can be seen on the Studio Fields page. This new statistic provides visibility into uses of fields that are not executed. It is also more efficient to generate and (for Apollo Gateways) does not require subgraphs to support federated tracing. Additionally, the newfieldLevelInstrumentation
option toApolloServerPluginUsageReporting
allows you to disable field-level tracing on a per-operation basis, and to report weights for operations to allow for estimates of the field execution count even when not all operations are instrumented. Note that the semantics of therequestContext.metrics.captureTraces
field have changed. See the Studio Fields page docs and thefieldLevelInstrumentation
docs for more details. Issue #5708 PR #5956 PR #5963apollo-server-core
: Usage reporting no longer sends a "client reference ID" to Apollo Studio (along with the client name and client version). This little-used feature has not been documented since 2019 and is currently entirely ignored by Apollo Studio. This is technically incompatible as the interfaceClientInfo
no longer has the fieldclientReferenceId
; if you were one of the few users who explicitly set this field and you get a TypeScript compilation failure upon upgrading to v3.6.0, just stop using the field. PR #5890apollo-server-core

: Error handling when aserverWillStop
callback invoked byserver.stop()
(orgateway.stop()
) throws is now consistent: the original call toserver.stop()
throws the error, and any concurrent and subsequent calls toserver.stop()
throw the same error. Prior to Apollo Server v2.22.0, the original call threw the error and the behavior of concurrent and subsequent calls was undefined (in practice, it would call shutdown handlers a second time). Apollo Server v2.22.0 intended to put these semantics into place where all three kinds of calls would throw, but due to bugs, the original call would return without error and concurrent calls would hang. (Subsequent calls would correctly throw the error.) In addition, errors thrown by thedrainServer
hook introduced in Apollo Server v3.2.0 are now handled in the same way. Issue #5649 PR #5653v3.2.0

, it should setmaxAge
to 60 even if the default max age is lower. (This bug fix is the behavior that was intended for 3.0.0, and primarily affects the behavior of functions added in Apollo Server 3. This does mean that checkinginfo.cacheControl.cacheHint
now only shows explicitly-setmaxAge
and not the default, but this seems like it will be helpful since it lets you differentiate between the two similar circumstances.) PR #5492apollo-server-lambda

BREAKING CHANGES
Apollo Server 3 contains quite a few breaking changes. Read our migration guide for more details on how to update your app.
Bumped dependencies
The minimum versions of these dependencies have been bumped to provide an improved foundation for the development of future features.

constructor now uses@graphql-tools/mock

argument toaddMocksToSchema
. Apollo Server does not support this option, but you can calladdMocksToSchema
yourself and pass the result to theschema
option of theApolloServer
constructor.Removed functionality
Certain undersupported and underused Apollo Server features have been removed in favor of current or future methods for achieving similar functionality. Many of these features can be manually re-enabled, as listed below.
Dropped built-in partial support for subscriptions via the
subscriptions-transport-ws
package.subscriptions-transport-ws
has not been actively maintained.Dropped built-in support for file uploads via the
graphql-upload
package.Dropped support for the
graphql-extensions
API (e.g.,GraphQLExtensions
,extensions
) in favor of the Apollo Server plugins API.Dropped support for passing the
schemaDirectives
option to theApolloServer
constructor.This option was passed directly to the
graphql-tools
functionmakeExecutableSchema
. To continue using it, you can importmakeExecutableSchema
from@graphql-tools/schema
and call it yourself:Note that
graphql-tools
calls this feature "legacy" schema directives, and you might want to consider the newerschemaTransforms
option instead.Removed the deprecated
ApolloServer.schema
field, which never worked with federated gateways.serverWillStart
or registeronSchemaChange
on your gateway.apollo-datasource-rest
: We no longer officially support overriding thebaseURL
property with a getter, because TypeScript 4 does not allow you to do so.Removed the automatic addition of the
@cacheControl
directive to schemas.@cacheControl
, you can define it in your schema as shown in the docs.Removed the
tracing
option passed to theApolloServer
constructor. The correspondingapollo-tracing
package has been deprecated and is no longer being published.This package implemented an inefficient JSON format for execution traces returned via the
tracing
GraphQL response extension. This format was only consumed by the deprecatedengineproxy
and GraphQL Playground.If you rely on this trace format, the old version of
apollo-tracing
should still work:Removed a redundant mechanism for applying extensions to an
ApolloError
.error.extensions
, and are not also available onerror
itself.ForbiddenError
andAuthenticationError
constructors now allow you to pass additional extensions.Removed the
cacheControl
option passed to theApolloServer
constructor.Cache-Control
HTTP header. However, this is now implemented directly insideapollo-server-core
instead of inside a separateapollo-cache-control
package (this package has been deprecated and is no longer being published).defaultMaxAge
is now done via the newly exportedApolloServerPluginCacheControl
plugin, instead of as a top-level constructor option. This follows the same pattern as other built-in plugins like usage reporting.CacheHint
andCacheScope
types are now exported fromapollo-server-types
. Theinfo.cacheControl.cacheHint
object now has additional methods (replace
,restrict
, andpolicyIfCacheable
), and its fields update when those methods orsetCacheHint
are called. These methods also exist onrequestContext.overallCachePolicy
, which is always defined and which should not be overwritten (usereplace
instead). There is also a new functioninfo.cacheControl.cacheHintFromType
available.@cacheControl
directives on type extensions are no longer ignored. Fields returning union types are now treated similarly to fields returning object and interface types (@cacheControl
directives on the type are honored, the defaultmaxAge
is applied to them).@cacheControl(inheritMaxAge: true)
when applied to a composite type or a field returning a composite type means that the defaultmaxAge
is not applied to that field (unless it is a root field).Due to conflicts with same/similar globals provided by
@types/supertest
(which we use in our testing), some global TypeScript definitions have been removed fromapollo-server-env
including that of, e.g.,fetch
,RequestInfo
,Headers
,Request
,Response
,ResponseInit
, and more. See the full list prior to removal here. Internally in the Apollo Server tests, for the time-being, we are relying on the same-named types from TypeScript'slib.dom.d.ts
— e.g., itsRequestInfo
type definition. For more details, see PR #5165.Top-level exports have changed. For example:
graphql-tools
(includingmakeExecutableSchema
) from all Apollo Server packages. To continue using them, installgraphql-tools
or one of its sub-packages yourself.Upload
scalar is no longer exported as part of dropping built-in support for file uploads.Stopped publishing the deprecated
apollo-server-testing
package. This package is just a wrapper aroundserver.executeOperation
, which you can use directly.apollo-server-caching
: The test suite helper works differently, and theTestableKeyValueCache
interface is removed.The
engine
constructor option,ENGINE_API_KEY
environment variable, andENGINE_SCHEMA_TAG
environment variables are no longer supported. Use theapollo
constructor option,APOLLO_KEY
environment variable, andAPOLLO_GRAPH_VARIANT
environment variable instead, as described in [theengine
option migration guide from v2.18)[https://www.apollographql.com/docs/apollo-server/v2/migration-engine-plugins/].When you supply an Apollo API key via the
APOLLO_KEY
environment variable ornew ApolloServer({apollo: {key}})
, Apollo Server 3 no longer parses the key to guess your Studio graph ID. You must specify it yourself, either via theAPOLLO_GRAPH_ID
environment variable (ornew ApolloServer({apollo: {graphId}})
), or as a graph ref along with the variant (e.g.,your-graph-id@your-graph-variant
) in theAPOLLO_GRAPH_REF
environment variable (ornew ApolloServer({apollo: {graphRef}})
).Modified functionality

(with most query parameters removed). This means you typically don't have to manually configure the endpoint when using GraphQL Playground.ApolloServerPluginLandingPageDisabled

before attaching the server to your framework.apollo-server
library or to serverless framework integrations.apollo-server-express
no longer officially supports using with theconnect

All integrations that allow CORS headers to be customized now default to
access-control-allow-origin: *
. This was already the case forapollo-server
, Express, Fastify, and Hapi; it is now also the same for Koa (which previously reflected the request's origin), Lambda, Cloud Functions, and Azure Functions as well (which did not set CORS by default). Micro and CloudFlare do not have a built-in way of setting CORS headers.v2.25.3

graphql@15
without causing peer dependency errors or warnings. (Apollo Server has a file upload feature which was implemented as a wrapper around thegraphql-upload
package. We have been unable to upgrade our dependency on that package due to backwards-incompatible changes in later versions, and the version we were stuck on did not allowgraphql@15
as a peer dependency. We have now switched to a fork of that old version called@apollographql/graphql-upload-8-fork
that allowsgraphql@15
.) Also bump thegraphql-tools
dependency from 4.0.0 to 4.0.8 forgraphql@15
support. Issue #4865v2.20.0

apollo-server
: Previously,ApolloServer.stop()
functioned likenet.Server.close()
in that it did not close idle connections or close active connections after a grace period. This meant that trying toawait ApolloServer.stop()
could hang indefinitely if there are open connections. Now, this method closes idle connections, and closes active connections after 10 seconds. The grace period can be adjusted by passing the newstopGracePeriodMillis
option tonew ApolloServer
, or disabled by passingInfinity
(though it will still close idle connections). Note that this only applies to the "batteries-included"ApolloServer
in theapollo-server
package with its own built-in Express and HTTP servers. PR #4908 Issue #4097apollo-server-core
: When used withApolloGateway
,ApolloServer.stop

already invokesApolloGateway.load
which is what starts the behavior stopped byApolloGateway.stop
.) Note that@apollo/gateway
