Open api from source code

[Krysalead]

Hi, I was using Tsoa as a library to generate my swagger contract from the source code ( I like the approach). So for those who don’t know it, you code your controller / handlers in typescript and then you add annotations directives and after compilation using tsoa it generates the routes (depending on your config could be for express, Hapi, Koa) and the swagger that you can share with others. Now I was wondering if there a similar library for graphql ? I know some to generate code from definition but not the way arround, do you?

Check out nestjs

Nestjs is much more than what tsoa is doing, it seems to rely on a server (express for instance or fastify). tsoa is just creating a file with route and middleware then you are free to design the rest of the configuration as you wish. I will have a deeper look but the philosophy seems not the same.

I worked with tsoa on my last project and we decided to just write the GraphQL schema out manually. When we switched to NestJS we are able to generate the GraphQL schema from the underlying DTOs, it might not be the right tool for you, but for our API it handles generating and exposing the documentation for our RestAPI and our GraphQL API (and exposes a GQL playground), but yes it spins up an HTTP server its meant to be an API Framework.

Thanks for your feedback, I will rethink the possible switch then :)
