BTP API NestJS without approuter

[LuizGomes]

Is it possible to develop an API with BTP JWT authentication but without using the approuter? A totally independent API?

Short answer: Yes, this is possible.

The long answer is, as you can expect, a bit more complicated: You don't need to use the approuter to authenticate users. E.g. you can use CAP to implement an UI and use any webserver to access this API. As you mentioned NestJS in your question, you probably don't want to use CAP either. In this case, I'd recommend that you check out the following package:
