flask-mini-rest VS swagger-typescript-api

Somewhere else, I have my previous flask-mini-rest up and running in localhost:5000. (Recently I pushed some changes in order to support CORS and improve the Swagger model documentation).

RESTful APIs via swagger-typescript-api

TypeScript API generator via Swagger scheme

You said it yourself — the “official” generator is awful and very hard to modify or extend (well, you didn’t say that, but I’m saying it) and while there are many alternatives, they’re not always easy to find. I had some success with swagger-typescript-api[1], but eventually got tired of it and wrote my own generator. Despite looking around quite a bit at what’s available, I never heard of openapi-codegen, which looks quite good.

A lot of APIs nowadays have a Swagger / OpenAPI spec. You can autogenerate types from that using tools like swagger-typescript-api.

With such a contract your BE team should provide a https://swagger.io/tools/swagger-ui/ where the API definition can easily be viewed and tested. Also you can use generators to basically generate a boilerplate (types for all models, functions for all requests) for the entire API based on a contract: https://github.com/acacode/swagger-typescript-api This his already saved me months of work.. great tool.

If your backend is using Swagger, I'd highly recommend using the package swagger-typescript-api. It auto-generates your types and endpoints for you, based on a swagger.json file, which then simplifies where I store my API calls. The flexibility of this is that I can use these API calls in components, classes, Vuex, etc., and I'm not tied to something that I have to maintain as a UI dev.

If your backend is able to generate Swagger/OpenAPI JSON, you can use https://github.com/acacode/swagger-typescript-api to generate both TypeScript interfaces and an API client from the Swagger JSON.
