Node JS

Node JS

Node.js (Node) is a platform for executing JavaScript code server-side which is useful for developing applications that require a persistent connection from the browser to the server. It was developed by Ryan Dahl.

It is an open source platform and is often used for real-time applications such as chat, news feeds, and web push notifications. Javascript rising popularity in the youth, as well as the market, has marked a huge difference in the present scenario. The reach of the internet, development of web browser, developing applications are all a boon to the present society.Node.js is a complete package of Google’s V8 JavaScript engine with the libuv platform abstraction layer, and a core library, which is itself primarily written in JavaScript. Node.Js was inspired by applications like Gmail to create an easy user interface. Node.js provides developers a tool for working in the non-blocking, event-driven I/O paradigm.

We start from the basics and scratch by starting with an introduction to Node.Js. in this we teach about what is Node.Js, its advantages, the process model of Node.Js and traditional web server model. then we learn about how to set up and install Node.Js and how to maintain its environment by working in REPL and Node.Js console. Then we focus on various Node.Js modules like core modules, module types, buffer, functions, local modules and module exports. The Node package manager is next discussed in depth. In this, we teach on how to install packages globally, locally and also to update packages. We will also teach you about how to create a server, handle POST, PUT, HTTP server and requests. How to open, handle, read and create files are also practiced. We handle different files practically so the students can co-relate. Events and database connectivity are also discussed in depth. Event emitter class, returning event emitter, inhering events, working with select records and updating records are kept in focus. Serving static files, handling with middleware, how to use and create routes using express to design web applications. Node.js MongoDB and Node.jsMYSQL are last being complex than others.the drop data table, creating a connection, database, record, table and everything related to it is briefly discussed.


  • Understand the  technical concepts of Javascript behind Node JS.
  • Understand Buffers, Streams, and Pipes, use of event emitter, the structure  of modules in Node applications.
  • How to Build a Web Server and build a web application in Node and understand how it works in the web field.
  • Connect to a SQL or Mongo database in Node using Node.js applications.
  • Understand and learn how to use MEAN stack works.

Web Designers, software programmers, Front End Developers who wish to excel and become professional in the fields of web applications can take this course. Absolute beginners with basic knowledge of HTML, CSS, and Javascript, ASPnet, Perl, Java & Ruby coders wanting to leap onto the NodeJs bandwagon can also apply to improve their skills.

Basic Knowledge of JavaScript and OOPS, Knowledge in async programming will be added advantage.

In this module, you learn What is Node JS and advantages of Node JS and How Node JS Works and the difference between the traditional web server and what are the limitations of the traditional web server modal.
