What is up fellow coder.
Thank you for checking out my article on Understanding REST methods and its correlation with EXPRESS server.
Lets get right into it!
Well it stands for Representational State Transfer.......
Ok, since this article is about REST methods associated with Express Router and Node.js. REST is the different HTTP routes that can define the relationship/interaction between the client/server for our applications.
And these methods can be used to map out CRUD (create, retrieve, update, delete) operations. An example of CRUD application can be Facebook, because you can create content, retrieve content, update content, and delete content.
Big Picture: when building a CRUD application you will need your
Lets take a look at some of the main REST methods and their correlation with a CRUD application.
GET - this method retrieves information, a GET request can be made by a client or server to get information from a database. (The retrieve part of CRUD)
