In programming terms, there is an endpoint (a URL) that the server is waiting to get a request. In very broad terms, you ask the server for a certain data or ask it to save some data, and the server responds to the requests. Other alternatives to this are: GraphQL, JSON-Pure and oData. We will talk about this in great detail below.

REST API: this defines the endpoint and methods allowed to access/submit data to the server.

There are many popular libraries that make creation of these servers a breeze, like ExpressJS for NodeJS and Django for Python. Others examples are code libraries like axios, superagent and got or some dedicated apps like Postman (or an online version, postwoman!), or a command line tool like cURL!. But, this was succeeded by FetchAPI, a modern, promise based approach to requests.

The browser, for a long time, used an in-built function called XMLHttpRequest for all REST requests. You are using one right now! Yes, the browser can act as an uncontrolled REST client (the website handles the browser requests). REST Client: code or an app that can access these REST services.

Okay, so now that you know what RESTful services are, here are some of the terms used in the heading: These intermediary servers (be it proxy or load balancers) allow for scalability and security of the underlying server. Layered system: client should not be able to tell if it is communicating directly with the server or some intermediary.This means each request to the server should be made with all the required data and no assumptions should be made if the server has any data from previous requests. Statelessness: the communication should have no client context stored on server.Client-Server Architecture: the user interface of the website/app should be separated from the data request/storage, so each part can be scaled individually.There are a few constraints on the definition of REST: REST is basically a set of rules for communication between a client and server.

Let's demystify what that means (hopefully you got the full form). RESTful Web services allow the requesting systems to access and manipulate textual representations of Web resources by using a uniform and predefined set of stateless operations So, what is REST? According to Wikipedia: Representational state transfer ( REST) is a software architectural style that defines a set of constraints to be used for creating Web services. Let's dive a bit deeper into JavaScript! Get that jargon away We'll declassify some of the jargon and have a look at how we can code a server in NodeJS. In this beginner friendly guide, I will walk you through the process of setting up a RESTful API. Ever wondered how login/signup on a website works on the back-end? Or how when you search for "cute kitties" on YouTube, you get a bunch of results and are able to stream off of a remote machine?
