Minor Changes

• #8148 80a1a1a Thanks @jerelmiller! - Apollo Server now supports the incremental delivery protocol (@defer and @stream) that ships with [email protected]. To use the current protocol, clients must send the Accept header with a value of multipart/mixed; incrementalSpec=v0.2.

  Upgrading to 5.1 will depend on what version of graphql you have installed and whether you already support the incremental delivery protocol.

  I use graphql@16 without incremental delivery

  Continue using graphql v16 with no additional changes. Incremental delivery won't be available.

  I use graphql@16 but would like to add support for incremental delivery

  Install [email protected] and follow the "Incremental delivery" guide to add the @defer and @stream directives to your schema. Clients should send the Accept header with a value of multipart/mixed; incrementalSpec=v0.2 to get multipart responses.

  I use [email protected] and use incremental delivery

  You must upgrade to [email protected] to continue using incremental delivery. If you'd like to continue providing support for the legacy incremental protocol, install the @yaacovcr/transform package. Apollo Server will attempt to load this module when the client specifies an Accept header with a value of multipart/mixed; deferSpec=20220824. If this package is not installed, an error is returned by the server.

  Because Apollo Server now supports multiple versions of the incremental delivery types, the existing incremental delivery types have been renamed with an Alpha2 suffix. If you import these types in your code, you will need to add the Alpha2 suffix.

  import type {
  - GraphQLExperimentalFormattedInitialIncrementalExecutionResult,
  + GraphQLExperimentalFormattedInitialIncrementalExecutionResultAlpha2,
  
  - GraphQLExperimentalFormattedSubsequentIncrementalExecutionResult,
  + GraphQLExperimentalFormattedSubsequentIncrementalExecutionResultAlpha2,
  
  - GraphQLExperimentalFormattedIncrementalResult,
  + GraphQLExperimentalFormattedIncrementalResultAlpha2,
  
  - GraphQLExperimentalFormattedIncrementalDeferResult,
  + GraphQLExperimentalFormattedIncrementalDeferResultAlpha2,
  
  - GraphQLExperimentalFormattedIncrementalStreamResult,
  + GraphQLExperimentalFormattedIncrementalStreamResultAlpha2,
  } from '@apollo/server';

  Incremental delivery types for the [email protected] version are now available using the Alpha9 suffix:

  import type {
    GraphQLExperimentalFormattedInitialIncrementalExecutionResultAlpha9,
    GraphQLExperimentalFormattedSubsequentIncrementalExecutionResultAlpha9,
    GraphQLExperimentalFormattedIncrementalResultAlpha9,
    GraphQLExperimentalFormattedIncrementalDeferResultAlpha9,
    GraphQLExperimentalFormattedIncrementalStreamResultAlpha9,
    GraphQLExperimentalFormattedCompletedResultAlpha9,
    GraphQLExperimentalPendingResultAlpha9,
  } from '@apollo/server';
