It will also change the generators so that it won't generate views, helpers, and assets when generating a new resource. This includes things like sessions, cookies, assets, and really anything related to making Rails work with a browser. We do that by passing the -api directive to the rails new command.įor the most part, what the API mode does is remove functionality that you don't actually need when building an API.

In this article, we will investigate how to take advantage of the rails-api gem, which now comes built in. It gives us the power of Rails but with only the functionality that we’re actually going to need for our JSON API. That's where using Rails in -api mode comes in handy. It's also great for building JSON APIs, but why include a whole bunch of functionality that we aren't going to use if what we want is to simply build a JSON API? It has support for cookies, sessions, and other browser-specific functionality right out of the box. Rails is great for making traditional server-rendered web applications.
