## What it is
GraphQL Code Generator is a plugin-based CLI tool that generates typed code from GraphQL schemas and operations (queries, mutations, subscriptions, fragments). It supports many output targets including TypeScript types, typed React/Vue/Angular hooks, typed resolvers, and SDKs, with a rich ecosystem of community and custom plugins.

## Use cases
- generate TypeScript types from a GraphQL schema
- generate typed React hooks for GraphQL queries and mutations
- generate typed GraphQL resolvers for a Node.js server
- create a fully-typed GraphQL SDK for my API
- avoid hand-writing types for GraphQL operations
- generate GraphQL client code for Vue or Angular
- write a custom codegen plugin for my GraphQL stack

## When to choose
- you use GraphQL and want end-to-end type safety between schema, client, and server
- you work with React, Vue, Angular, Svelte, or Next.js and want typed queries/mutations
- you want typed resolvers for Node.js or Java GraphQL servers
- you need customizable code generation via plugins or presets

## When to avoid
- your project does not use GraphQL
- you prefer hand-written types or a different codegen approach
- you need a non-JavaScript toolchain without Node.js available
