TypeScript ♥ OpenAPI

Automatically get accurate, complete, correct and up-to-date OpenAPI Specifications from your TypeScript code

Type-safe

No more manual validation. tsoa makes sure the input can be assigned according to the types you specified or will throw automatically if it can't.

Proven foundation

tsoa-next continues the original tsoa project by Luke Autry and contributors, carrying forward the stable TypeScript-first and OpenAPI-first workflow they established.

Flexible

Doesn't matter if you use express, koa, hapi or your own framework. We can support it out of the box or with a custom template.

Generate OpenAPI from TypeScript without drift

tsoa-next keeps your controllers, runtime validation, generated routes, and OpenAPI output aligned so API docs stay accurate as your code evolves.

The docs here cover setup, generation, decorators, validation, file uploads, authentication, dependency injection, and template customization for Express, Koa, Hapi, and related server stacks.

What teams use tsoa-next for

Generate OpenAPI 2 and OpenAPI 3 specs directly from TypeScript controllers and models
Produce framework-aware route handlers for Express, Koa, Hapi, and custom templates
Enforce runtime request validation that matches the generated schema contract
Document authentication, examples, descriptions, and annotations in one maintainable workflow
