Node.JS

Description : 

Node.js is an open-source and cross-platform JavaScript runtime environment. It is a popular tool for almost any kind of project!

A Node.js app runs in a single process, without creating a new thread for every request. Node.js provides a set of asynchronous I/O primitives in its standard library that prevent JavaScript code from blocking and generally, libraries in Node.js are written using non-blocking paradigms, making blocking behavior the exception rather than the norm.

When Node.js performs an I/O operation, like reading from the network, accessing a database or the filesystem, instead of blocking the thread and wasting CPU cycles waiting, Node.js will resume the operations when the response comes back.

Express.JS:

Express. js is a free and open-source web application framework for Node. js. It is used for designing and building web applications quickly and easily. Web applications are web apps that you can run on a web browser.

Rest API:

A RESTful API is an architectural style for an application program interface (API) that uses HTTP requests to access and use data. That data can be used to GET, PUT, POST and DELETE data types, which refers to the reading, updating, creating and deleting of operations concerning resources.

Socket.IO:

Socket.IO is a library that enables real-time, bidirectional and event-based communication between the browser and the server. It consists of: a Node.js server: Source | API.
