From raywenderlich.com:

IBM created Kitura as an open-source framework in 2015, shortly after Apple open-sourced Swift. They modeled Kitura after Express.js, the de-facto framework for creating RESTful APIs using Node.js.

REST is an acronym for Representational State Transfer. In RESTful apps, each unique URL represents an object. Non-unique URLs represent actions, which are combined with RESTful verbs like GET to fetch objects, POST to insert, DELETE to remove and PUT to update objects.

Backend development often involves many components working together. You’ll only be concerned with two backend components in this Kitura tutorial: the API and database.

For example, if you want to populate a table view with a list of acronyms and their meanings, your client app sends a GET request to the backend. In practice, your app requests the URL http://yourAPI.com/acronyms.

The API receives your request and uses a router to decide how to handle it. The router checks all available routes, which are simply publicly accessible endpoints, to determine if there is a GET route ending in /acronyms. If it finds one, it executes the associated route’s code.

The /acronyms route then does the following:

Retrieves the acronyms from the database
Serializes them into JSON
Packages them into a response
Returns the response to the API to send to the client
