spectrum VS tsoa

Disclosure: I'm a contributor to the project.

OpenAPI Spec and auto-generated API clients are very useful when multiple languages need to be supported, like when running a developer program. I've worked at companies that both use OpenAPI Generator for official clients and ones that wrote our own tools for API client SDK generation (with different design philosophy). I've used a number of generators myself to compare and submitted fixes / enhancements to OpenAPI Generator. I used the Go client generator a while back and compared it to others, and recently started using the Crystal one.

To get the most the project, the following is useful: (a) need to support multiple languages, (b) ability to update the generator's code, both in Java and templates (Mustache or Handlebars), and (c) ability to discuss design in GitHub issues and the Slack channel.

The nice thing about OpenAPI Spec is that there is an ecosystem of tooling to support it, including rendering API references (HTML and PDF), API explorers (HTML pages to execute API calls), API clients, etc. But there is a learning curve. For writing specs by hand, I use and favor the Stoplight Studio IDE ( https://stoplight.io/studio ). For programmatically analyzing and editing specs, which is especially useful for finalizing auto-generated specs, I've built an OpenAPI Spec SDK library to make this easier ( https://github.com/grokify/spectrum ).

Tsoa is a popular TypeScript framework similar to Goa that you may encounter in the OpenAPI ecosystem. Speakeasy has a tutorial for it, too.

Currently i am using TSOA and loving it, it gives you automatic Open API specs and data validation based on typescript interfaces. I have used Nest on previous projects but I personally don't like the decorators hell that comes with Nest, and raw express/fastify are ok and easy to use but a pain in the ass on big projects to keep swagger, validations, interfaces and DTOs all in sync.

I'm curious if anyone here has played around with or used TSOA (https://github.com/lukeautry/tsoa)?

If you decide to go with Express/Typescript I would definitely check out TSOA. It's a nice way to build backend APIs with auto documentation.

We are using TSOA to generate the docs from the code, works pretty well. https://github.com/lukeautry/tsoa

This is the best project I’ve found to that for that - https://github.com/lukeautry/tsoa. Uses decorators mainly.

If there are other such projects, please share.

Hello, In the last month I built a REST API template in Typescript to quickly bootstrap new projects, I tried to use the most updated modules available, I've also included a "todo" sample just to showcase how all the things work together, the main modules that I've used are: - expressjs + tsoa that allows to easily generate the OpenAPI spec without any additional steps (just declare your controllers via typescript) - class-validator to validate body requests (this is also useful as the OpenAPI will be automatically generated based on the classes that you define) - Jest for testing, I've included also unit and integrations test samples with an in-memory database

Have a look at [TSOA[(https://github.com/lukeautry/tsoa). While far from perfect (I am on the lookout to find a better solution), gets the job done. And generating the entire routing is a pretty neat trick, so that's also that.

tsoa Lighter weight, but also great.
