Stop Advertising in Your Commits
To be fair I've never used Laravel - but I do have a memory of code generators/scaffolders inserting files that made clear they were responsible for work

From Swagger UI to React: Building qcontroller's Frontend
For the REST API communication, I leveraged OpenAPI Generator to automatically generate TypeScript client code. This API-first approach eliminates the common frontend-backend synchronization problems and ensures type safety across the entire stack.

Type safe web stack with Rust and TypeScript
> Ideally I'd like to be able to write types in typescript, and write python types, then verify that the types are compatible (not identical)
Have a look at https://fastapi.tiangolo.com/
FastAPI allows you to define your types in Python using Pydantic for stronger type guarantees. FastAPI also generates an OpenAPI.json file for your backend and then you can feed this OpenAPI.json document into https://github.com/OpenAPITools/openapi-generator to generate a typescript library that contains all the types. Then you don't need to verify your types, because the typescript types will be directly generated from your Python types. The generated typescript library also contains methods for each of your REST endpoints, so that you don't have to think about network requests.

How and Why to Use Patches
Patches are also useful if we're making manual modifications to any codebase that is being auto-generated, i.e. if we're using openapi-generator off of an OpenAPI spec to create clients and scaffolded server codebases. We would want to maintain the patch as a way to ensure that subsequent re-generations of the code don't wipe out any manual changes we have to make in-between.
