Mobile application automation. How to mock a server?

Question

Android

Hello
This is the thing
There is a mobile application
There is an appium and knowledge of programming languages
​​I would like to find an option how I can run the application in the test, use it -> it will send HTTP requests (GET / POST), but not to the server, but to the stub
How is this organized?
As an option, I see proxying requests and passing them to something self-written on some NodeJS, for example.
Maybe there are good ready-made solutions or successful practices?
Thanks

You make an env file in the application, in the env file you specify the address of mock_api as a host, in mock_api you make stubs for the test data you need.
