tsoa

Pronounced so·uh OpenAPI-compliant REST APIs using TypeScript and Node ![build status](https://github.com/lukeautry/tsoa/actions/workflows/runTestsOnPush.yml/badge.svg) [![npm version](https://img.shields.io/npm/v/tsoa/latest)](https://www.npmjs.com/package/tsoa)

## Goal - TypeScript controllers and models as the single source of truth for your API - A valid OpenAPI (formerly Swagger) spec (2.0 or 3.0 if you choose 😍) is generated from your controllers and models, including: - Paths (e.g. GET /users) - Definitions based on TypeScript interfaces (models) - Parameters/model properties marked as required or optional based on TypeScript (e.g. myProperty?: string is optional in the OpenAPI spec) - jsDoc supported for object descriptions (most other metadata can be inferred from TypeScript types) - Routes are generated for middleware of choice - Express, Hapi, and Koa currently supported, other middleware can be supported using a simple handlebars template - Validate request payloads ## Philosophy - Rely on TypeScript type annotations to generate API metadata if possible - If regular type annotations aren't an appropriate way to express metadata, use decorators - Use jsdoc for pure text metadata (e.g. endpoint descriptions) - Minimize boilerplate - Models are best represented by interfaces (pure data structures), but can also be represented by classes - Runtime validation of tsoa should behave as closely as possible to the specifications that the generated OpenAPI 2/3 schema describes. Any differences in validation logic are clarified by logging warnings during the generation of the OpenAPI Specification (OAS) and/or the routes. - Please note that by enabling OpenAPI 3 you minimize the chances of divergent validation logic since OpenAPI 3 has a more expressive schema syntax. ## Getting Started - [Documentation](https://tsoa-community.github.io/docs/) - [API Reference](https://tsoa-community.github.io/reference/) - [Getting started guide](https://tsoa-community.github.io/docs/getting-started) ## Examples Check out the [guides](https://tsoa-community.github.io/docs/getting-started) See example controllers in [the tests](tests/fixtures/controllers) See example models in [the tests](tests/fixtures/testModel.ts) ## Help wanted ### Contributing code To contribute (via a PR), please first see the [Contributing Guide](https://github.com/lukeautry/tsoa/tree/master/docs/CONTRIBUTING.md) ### Becoming a maintainer tsoa wants additional maintainers! The library has increased in popularity and has quite a lot of pull requests and issues. [Please post in this issue](https://github.com/lukeautry/tsoa/issues/236) if you're willing to take on the role of a maintainer.
