What is the webmachine gem used for?

Question

Ruby on Rails

In the project, I came across gem 'webmachine'. What is its fundamental difference from a web server? An opinion from practice is needed, not excerpts from the documentation (I have already looked at it).

Answer 1

This is not exactly a web server, but rather a framework for building a RESTful API. Like its predecessor, it allows you to create REST interfaces using callbacks rather than routing. I used the version for Erlang, it greatly simplifies the task for the developer and API user, because less thinking about response statuses and headers.
