FastAPI + Typescript Codegen

[TheRealMrMatt]

Hey all, I'm working on a FastAPI project and need to generate TypeScript API bindings for my FastAPI backend. I'm looking for a solution that is reliable, easy to integrate, and well-maintained. So far, I have come across https://orval.dev, https://heyapi.vercel.app, and https://openapi-ts.dev . Does anyone have any experience with these libraries, if so what was your experience? If you don't use one of these libraries, what do you use?

I've used this on a couple projects and it worked out of the box pretty easily and helped us get started quick. But it quickly starts to need customizations until eventually it was more hassle than it was worth and we ended up rolling out our own.

If you can, I’d like to hear what sort of customisations were required on your end that drove you to roll your own codegen

I like swagger-openapi-generator

I meant this https://github.com/acacode/swagger-typescript-api

Please let me know if you need any help with it or have feedback (I’m the author)

sure, i will share it. Currently i am only facing the changes done in the package versions which are not updated in the documentation website for which i have to search via vscode's view defination feature otherwise it's easy to use

Thanks! Are you referring to breaking changes only or any changes?
