Introduction

JavaScript’s rising popularity has brought with it a lot of changes, and the face of web development today is dramatically different. The things that we can do on the web nowadays with JavaScript running on the server, as well as in the browser, were hard to imagine just several years ago or were encapsulated within sandboxed environments like Flash or Java Applets.

Node.js is a packaged compilation of Google’s V8 JavaScript engine, the libuv platform abstraction layer, and a core library, which is itself primarily written in JavaScript.” Beyond that, it’s worth noting that Ryan Dahl, the creator of Node.js, was aiming to create real-time websites with push capability, “inspired by applications like Gmail”. In Node.js, he gave developers a tool for working in the non-blocking, event-driven I/O paradigm.

After over 20 years of stateless-web based on the stateless request-response paradigm, we finally have web applications with real-time, two-way connections.

WHY NODEJS TRAINING IN NEPAL?

Node.js is an open-source server-side platform that allows developers to build scalable, high-performance applications using JavaScript.

Node.js uses JavaScript, a programming language that many developers are already familiar with.
Node.js is designed to handle large-scale applications with ease, making it an ideal choice for building high-performance applications that can handle a large number of users and requests.
Node.js allows developers to write server-side code in JavaScript, enabling them to build both the client and server-side of the application using the same language. This can lead to faster development times and reduced development costs.
Node.js is currently one of the most in-demand technologies in the industry.
Node.js can be used to build a variety of applications, including web applications, APIs, real-time applications, and microservices.

Course overview

Node.js is a server-site platform built on Google chrome’s JavaScript Engine. This platform was developed by Ryan Dahl in 2009. Node.js is an open source, cross-platform runtime environment to develop server-side and network application. Node.js application is written in JS (JavaScript), and can be run within the node.js runtime on OSX, Linux, and Microsoft Windows.

Node.js application is written in JS (JavaScript), and can be run within the Node.js runtime on OSX, Linux, and Microsoft Windows.If you write front-end code, it shouldn’t be a sudden news for you that you could easily write web apps with Node.js, since both relay on JavaScript.

Why NodeJS Training?

Before starting why, here’s the formal definition given on official website.

Node.js® is a JavaScript runtime built on Chrome’s V8 JavaScript engine. Node.js uses an event-driven non-blocking I/O model that makes it lightweight and efficient. Node.js’ package ecosystem, npm, is the largest ecosystem of open source libraries in the world.”

If you are a JavaScript developer or willing to learn scripting language, then this is the best option. Every time you switch your programming platform, you will definitely have some problem. Typically, Node.js and its ecosystem stay with JS on both front-end and back-end.

Just imagine a multi-threaded server that reads file saved on the server and sends it to the requesting browser. Ruby just tell the file system to read the file and return the content. Which slow-down the request-response operation. And here comes the Node.js, in node while the file.

System is reading file in server, node uses idle time to handle other pending request. When the file system is done, it tells the node to take resource and send it to browser.

Its improved framework like React Native which let you to make mobile applications. This is a huge advantage now that everything you build will also work as mobile application, Which will surely help you in future if you want to monetize your web pages.

Another fantastic usage of Node.js is chatting system in websites. You can make your own chat system using Node.js.

Career opportunity in NodeJS

You could get a job specializing in backend programming using Node.js. You could start a career where your elementary language is JavaScript via node. You can even start your career as startup engineer where you can build your own portfolio and client may contact you to solve their problem.

The major objective of this course is to understand the Javascript and technical concepts behind NodeJS by understanding:

Structure a Node application in modules
Understand and use the Event Emitter
Understand Buffers, Streams, and Pipes
Build a Web Server in Node and understand how it really works
Use npm and manage node packages
Build a web application and API more easily using Express
Connect to a SQL or Mongo database in Node
Understand how the MEAN stack works

Teaching Methodology

Handful of assignments, tutorials and lab test of each chapter.
Periodic feedback from Trainer and Trainee and do the required changes as per necessity.
Each trainee need to develop demo application on their own, taking assistance form trainer when ever required.

Prerequisites

Good command in english language
Good knowledge of Computer, Softwares
Basic Knowledge Javascript Programming Language and Object Oriented Programming would be a plus
Understanding of Softwares and Software installation.
