Interceptor to ignore server request

[mars3142]

I want to build a preview app, where I can inject static json responses. Now my question. What can I do to stop the request to the server and return this json as a response? I don't want the app to do a server call, because the result will be thrown away.

A ResponseInterceptor can override my server result, but this isn't needed.

Any ideas for that?

You should mock your http client and return specific static JSON for a specific URL.
