pe-mocks

Component for client-side mocking of the REST API. As a sitedev, leave a 
certain class on a node, then register interceptors for certain methods 
(GET, POST, PUT, DELETE) and certain patterns. The interceptor can be a 
simplified (default to GET with a generic response) or slightly more verbose.

Anyway, I do not think it is a major problem, and if a solution exists, it will be easy to implement it later (as it is not deeply anchored in the code, put just added at the begining of our module).
