Quick Start

Create a new TSDIAPI project in seconds:

npx @tsdiapi/cli create myapi
cd myapi

Type-Safe Routes

Write fully type-safe API endpoints:

export default function userController({ useRoute }: AppContext) {
  useRoute()
    .get("/users/:id")
    .params(Type.Object({ id: Type.String() }))
    .code(200, Type.Object({ 
      id: Type.String(), 
      name: Type.String() 
    }))
    .handler(async (req) => {
      return {
        status: 200,
        data: { 
          id: req.params.id, 
          name: "John Doe" 
        }
      };
    })
    .build();
}
