The graphql
module exports a core subset of GraphQL functionality for creation of GraphQL type systems and servers.

Entry Point
graphql
function graphql( schema: GraphQLSchema, requestString: string, rootValue?: any, contextValue?: any, variableValues?: { [key: string]: any }, operationName?: string, ): Promise<GraphQLResult>; interface ExecutionResult< TData = ObjMap<unknown>, TExtensions = ObjMap<unknown>, > { errors?: ReadonlyArray<GraphQLError>; data?: TData | null; extensions?: TExtensions; }
The graphql
function lexes, parses, validates and executes a GraphQL request. It requires a schema
and a requestString
. Optional arguments include a rootValue
, which will get passed as the root value to the executor, a contextValue
, which will get passed to all resolve functions, variableValues
, which will get passed to the executor to provide values for any variables in requestString
, and operationName
, which allows the caller to specify which operation in requestString
will be run, in cases where requestString
contains multiple top-level operations.
