@graphql-codegen/typescript

What is @graphql-codegen/typescript?

The @graphql-codegen/typescript package is a powerful tool designed for generating TypeScript typings directly from GraphQL schemas and operations. It automates the process of creating type definitions, making it easier to work with GraphQL in TypeScript projects by ensuring type safety and reducing the manual effort required to keep types in sync with the GraphQL schema.

What are @graphql-codegen/typescript's main functionalities?

Generating TypeScript Types from a GraphQL Schema

This feature allows you to generate TypeScript interfaces and types from a GraphQL schema. The code sample demonstrates how to programmatically generate TypeScript types using the GraphQL Code Generator CLI.

const { generate } = require('@graphql-codegen/cli');

async function generateTypes() {
  const output = await generate(
    {
      schema: './schema.graphql',
      generates: {
        './types.ts': {
          plugins: ['typescript']
        }
      }
    },
    true
  );
}
generateTypes();

Generating TypeScript Operations (Queries, Mutations, Subscriptions)

This feature generates TypeScript types for GraphQL operations, such as queries, mutations, and subscriptions. The code sample shows how to generate types for operations, enhancing type safety and development experience in TypeScript projects.

const { generate } = require('@graphql-codegen/cli');

async function generateOperations() {
  const output = await generate(
    {
      schema: './schema.graphql',
      documents: './src/**/*.graphql',
      generates: {
        './graphql.ts': {
          plugins: ['typescript', 'typescript-operations']
        }
      }
    },
    true
  );
}
generateOperations();

Other packages similar to @graphql-codegen/typescript

apollo-client

Apollo Client is a comprehensive state management library for JavaScript that enables you to manage both local and remote data with GraphQL. While it provides strong integration with GraphQL, including generating types for operations, it is more focused on state management rather than solely on type generation like @graphql-codegen/typescript.

graphql-code-generator

GraphQL Code Generator is the core package that @graphql-codegen/typescript is a part of. It supports various plugins for different languages and tools, making it highly versatile. While @graphql-codegen/typescript focuses specifically on TypeScript, graphql-code-generator provides a broader ecosystem for code generation across different technologies.

type-graphql

TypeGraphQL is a framework for building GraphQL APIs in Node.js with TypeScript, focusing on defining the schema using TypeScript classes. Unlike @graphql-codegen/typescript, which generates types from an existing schema, TypeGraphQL allows you to create the schema directly from TypeScript classes, offering a different approach to integrating GraphQL with TypeScript.
