Major Changes

• 7d3e300: BREAKING CHANGE

  • Remove rootValue from subschemaConfig
  • • Pass it through ExecutionParams or delegation options
  • Do not pass info.rootValue if rootValue is falsy

• d53e3be: BREAKING CHANGES;

  Refactor the core delegation transforms into individual functions to modify request and results. This will improve the performance considerably by reducing the number of visits over the request document.

  • Replace CheckResultAndHandleErrors with checkResultAndHandleErrors
  • Remove delegationBindings
  • Replace AddArgumentsAsVariables, AddSelectionSets, AddTypenameToAbstract, ExpandAbstractTypes, FilterToSchema, VisitSelectionSets and WrapConcreteTypes with prepareGatewayRequest and finalizeGatewayRequest

• dae6dc7: refactor: ExecutionParams type replaced by Request type

  rootValue property is now a part of the Request type.

  When delegating with delegateToSchema, rootValue can be set multiple ways:

  • when using a custom executor, the custom executor can utilize a rootValue in whichever custom way it specifies.
  • when using the default executor (execute/subscribe from graphql-js):
    -- rootValue can be passed to delegateToSchema via a named option
    -- rootValue can be included within a subschemaConfig
    -- otherwise, rootValue is inferred from the originating schema

  When using wrapSchema/stitchSchemas, a subschemaConfig can specify the createProxyingResolver function which can pass whatever rootValue it wants to delegateToSchema as above.

• c42e811: BREAKING CHANGES;

  • Rename Request to ExecutionRequest
  • Add required operationType: OperationTypeNode field in ExecutionRequest
  • Add context in createRequest and createRequestInfo instead of delegateToSchema

  It doesn't rely on info.operation.operationType to allow the user to call an operation from different root type.
  And it doesn't call getOperationAST again and again to get operation type from the document/operation because we have it in Request and ExecutionParams

  Improvements;

  • Memoize defaultExecutor for a single GraphQLSchema so allow getBatchingExecutor to memoize batchingExecutor correctly.
  • And there is no different defaultExecutor is created for subscription and other operation types. Only one executor is used.

  Batch executor is memoized by executor reference but createDefaultExecutor didn't memoize the default executor so this memoization wasn't working correctly on batch-execute side.

• 7d3e300: BREAKING CHANGE

  • Now it uses the native AggregateError implementation. The major difference is the individual errors are kept under errors property instead of the object itself with Symbol.iterator.

  // From;
  for (const error of aggregateError)
  // To;
  for (const error of aggregateError.errors)

• aa43054: BREAKING CHANGE: validations are skipped by default, use validateRequest: true to reenable

• c0ca319: BREAKING CHANGE

  • Remove Subscriber and use only Executor
  • • Now Executor can receive AsyncIterable and subscriptions will also be handled by Executor. This is a future-proof change for defer, stream and live queries
