Doing API-first.

Start with defining the swagger.json Then generate:

- frontend-typings

- frontend request services

- backend routes and DTOs

- database fields

- use angular-jsonform for forms

- use the swagger for frontend validation

- use the swagger for backend validation

- use the swagger to discuss api changes with the client

This saves half of developing time and prevents 90% of your bugs

How though? All of the swagger open-api tooling is REALLY bad or abandonware. Did you write your own?

I can't speak for the GP but the way I've dealt with that is by using the tiny subset of tooling that isn't really bad, and supplementing it with some custom patches to make it also work.
