    Description

    This library provides the GraphQLRequestModule which makes it easy to initialize an instance of GraphQLClient for use in Depdendency Injection. This can be combined with automatic codegen for type safe access to third party GQL APIs from your Nest services

    Usage

    Install

    npm install ---save @golevelup/nestjs-graphql-request

    or

    yarn add @golevelup/nestjs-graphql-request

    Import

    Import and add GraphQLRequestModule to the imports section of the consuming module.

    import { GraphQLRequestModule } from '@golevelup/nestjs-graphql-request';
    
    @Module({
      imports: [
        GraphQLRequestModule.forRoot(GraphQLRequestModule, {
          // Exposes configuration options based on the graphql-request package
          endpoint: config.get('endpoint'),
          options: {
            headers: {
              'content-type': 'application/json',
              'x-hasura-admin-secret': config.get('secret'),
            },
          },
        }),
      ],
    })
    export class AppModule {
      // ...
    }

    Inject the GraphQLClient

    To make GraphQL requests from your controllers or services use the provided decorator @InjectGraphQLClient.

    import { InjectGraphQLClient } from '@golevelup/nestjs-graphql-request';
    import { GraphQLClient } from 'graphql-request';
    
    @Injectable()
    export class ExampleService {
      constructor(@InjectGraphQLClient() private readonly client: GraphQLClient) {}
    }

    Typesafe GraphQL Access

    The GraphQL client works best when combined with GraphQL code generation tools for communicating to a GraphQL endpoint. Follow the GraphQL Code Generator GraphQL Request Plugin Instructions.

    Running the code generator against a GraphQL Endpoint will produce typescript interfaces for all operations and types exposed by the API as well as a getSdk function which you can use in conjunction with GraphQL Request to get intellisense and type saftey for all requests you make. The getSdk function only requires a GraphQLClient instance (which this library provides). However because each generated SDK is unique per endpoint, it's up to you to wire up the provider for this in your application. This can be done using a Provider Factory with minimal code.

    import {
      GraphQLRequestModule,
      GraphQLClientInject,
    } from '@golevelup/nestjs-graphql-request';
    import { getSdk } from './your-codegen-location';
    
    @Module({
      imports: [
        GraphQLRequestModule.forRoot(GraphQLRequestModule, {
          // Exposes configuration options based on the graphql-request package
          endpoint: config.get('endpoint'),
          options: {
            headers: {
              'content-type': 'application/json',
              'x-hasura-admin-secret': config.get('secret'),
            },
          },
        }),
      ],
      providers: [
        {
          // you can provide whatever key you want. use it in conjunction with @Inject("TypeSafeGqlSdk") to get the SDK instance in your controllers/services
          provide: 'TypeSafeGqlSdk',
          inject: [GraphQLClientInject],
          useFactory: (client: GraphQLClient) => getSdk(client),
        },
      ],
    })
    export class AppModule {
      // ...
    }
