TypeGraphQL is a TypeScript framework for building GraphQL APIs using classes and decorators instead of SDL files, generating the schema from decorated object types and resolver classes. It includes built-in support for validation, authorization guards, dependency injection, middleware, and SDL emission.

Use cases

• build a GraphQL API in Node.js with TypeScript
• define GraphQL schema from TypeScript classes instead of SDL
• add auth guards and validation to GraphQL resolvers
• avoid type duplication between ORM entities and GraphQL types
• generate schema.graphql file for client tooling
• use dependency injection in GraphQL resolvers
• integrate GraphQL with TypeORM or MikroORM

When to choose

• you want a single source of truth between TypeScript types and GraphQL schema
• you prefer code-first schema definition with decorators
• you need built-in authorization, validation, and DI in resolvers
• your stack is Node.js with TypeScript and Apollo or graphql-js

When to avoid

• you prefer SDL-first schema design
• your project is JavaScript without TypeScript
• you need a stable 2.0 release - it is still in release candidate
• you use a non-Node.js backend language
