A set of utils for faster development of GraphQL tools



function addResolversToSchema

addResolversToSchema: ({
resolvers: inputResolvers,
}: IAddResolversToSchemaOptions) => GraphQLSchema;

    function assertResolversPresent

    assertResolversPresent: (
    schema: GraphQLSchema,
    resolverValidationOptions?: IResolverValidationOptions
    ) => void;

      function chainResolvers

      chainResolvers: <TArgs extends { [argName: string]: any }>(
      resolvers: Array<Maybe<GraphQLFieldResolver<any, any, TArgs>>>
      ) => (root: any, args: TArgs, ctx: any, info: GraphQLResolveInfo) => any;

        function checkForResolveTypeResolver

        checkForResolveTypeResolver: (
        schema: GraphQLSchema,
        requireResolversForResolveType?: ValidatorBehavior
        ) => void;

          function extendResolversFromInterfaces

          extendResolversFromInterfaces: (
          schema: GraphQLSchema,
          resolvers: IResolvers
          ) => IResolvers;

            function makeExecutableSchema

            makeExecutableSchema: <TContext = any>({
            }: IExecutableSchemaDefinition<TContext>) => GraphQLSchema;
            • Builds a schema from the provided type definitions and resolvers.

              The type definitions are written using Schema Definition Language (SDL). They can be provided as a string, a DocumentNode, a function, or an array of any of these. If a function is provided, it will be passed no arguments and should return an array of strings or DocumentNodes.

              Note: You can use GraphQL magic comment provide additional syntax highlighting in your editor (with the appropriate editor plugin).

              const typeDefs = /* GraphQL *\/ `
              type Query {
              posts: [Post]
              author(id: Int!): Author

              The resolvers object should be a map of type names to nested object, which themselves map the type's fields to their appropriate resolvers. See the [Resolvers](/docs/resolvers) section of the documentation for more details.

              const resolvers = {
              Query: {
              posts: (obj, args, ctx, info) => getAllPosts(),
              author: (obj, args, ctx, info) => getAuthorById(args.id)

              Once you've defined both the typeDefs and resolvers, you can create your schema:

              const schema = makeExecutableSchema({

            function mergeSchemas

            mergeSchemas: (config: MergeSchemasConfig) => GraphQLSchema;
            • Synchronously merges multiple schemas, typeDefinitions and/or resolvers into a single schema.

              Configuration object


            interface GraphQLSchemaWithContext

              property inheritResolversFromInterfaces

              inheritResolversFromInterfaces?: boolean;
              • GraphQL object types that implement interfaces will inherit any missing resolvers from their interface types defined in the resolvers object
