@types/graphql

What is @types/graphql?

@types/graphql provides TypeScript type definitions for the GraphQL JavaScript reference implementation. It allows developers to use GraphQL with TypeScript, ensuring type safety and better development experience.

What are @types/graphql's main functionalities?

Schema Definition

Defines a simple GraphQL schema with a single query field 'hello' that returns a string.

const { GraphQLSchema, GraphQLObjectType, GraphQLString } = require('graphql');

const schema = new GraphQLSchema({
  query: new GraphQLObjectType({
    name: 'RootQueryType',
    fields: {
      hello: {
        type: GraphQLString,
        resolve() {
          return 'Hello world!';
        }
      }
    }
  })
});

Type Definitions

Defines a GraphQL object type for a 'User' with 'id' and 'name' fields.

import { GraphQLObjectType, GraphQLString } from 'graphql';

const UserType = new GraphQLObjectType({
  name: 'User',
  fields: {
    id: { type: GraphQLString },
    name: { type: GraphQLString }
  }
});

Query Execution

Executes a simple GraphQL query against a schema and logs the response.

import { graphql, buildSchema } from 'graphql';

const schema = buildSchema(`
  type Query {
    hello: String
  }
`);

const root = { hello: () => 'Hello world!' };

graphql(schema, '{ hello }', root).then((response) => {
  console.log(response);
});

A community-maintained GraphQL server that works with any GraphQL schema. It includes features like caching, subscriptions, and more. It can be used with TypeScript but requires additional type definitions.

type-graphql

A library that allows you to define your GraphQL schema using TypeScript classes and decorators. It provides a more integrated TypeScript experience compared to @types/graphql.
