NodeJS Training Gurgaon


Introduction

Node.js is a powerful open-source framework based on JavaScript, which is used to develop highly scalable web applications. 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.

NodeJS is an asynchronous event driven JavaScript runtime, designed to build scalable network applications. Upon each connection the callback is fired, but if there is no work to be done Node is sleeping.

Modules in Node.js use an API designed to reduce the server complexity.Hence many connections can be handled concurrently. Upon each connection the callback is fired, but if there is no work to be done Node is sleeping.

Any input output operations are not directly performed in Node.js. So there are no deadlocks and writing code becomes easier. Node.Js can handle tens of thousands of simultaneous client connections efficiently which helps to develop highly scalable applications .

FAQ’s

  1. Why learn Node JS ?

    Node JS is designed to build scalable network applications through it asynchronous event driven javascript runtime.Many connections can be handled concurrently. Upon each connection the callback is fired, but if there is no work to be done Node is sleeping.

  2. Who can enroll for this course ?

    All the people who want to learn the basics of Node.js & its architectural concepts and also have an experienced background with at least one object oriented language like Ruby, Python, Java or PHP or having little knowledge of Javascript , or completely new to Node JS can enroll.

  3. Is Node JS an open source ?

    Yes , Node JS is an open source , completely free and is used by thousands of developers across the world.

  4. What is Node JS ?

    Node JS is simply a JavaScript runtime.It is not a web server. By itself it doesn't do anything. It doesn't work like Apache. There is no config file where you point it to you HTML files. If you want it to be a HTTP server, you have to write an HTTP server (with the help of its built-in libraries). Node.js is just another way to execute code on your computer.

  5. Who Uses Node.js?

    Organisations like eBay, General Electric, GoDaddy, Microsoft, PayPal, Uber, Wikipins, Yahoo!, Yammer are a few .

  6. Where to use Node JS ?

    Following are the areas where Node.js is proving itself as a perfect technology partner.

    • I/O bound Applications
    • Data Streaming Applications
    • Data Intensive Real time Applications (DIRT)
    • JSON APIs based Applications
    • Single Page Applications
  7. Where not to use Node JS ?

    It is advisable that Node JS should not be used for CPU intensive applications.

  8. What practical skills can i expect to have after completion of this course ?

    You will be able to develop and deploy Node.Js applications by yourself.

  9. What is the advantage of using Node.Js over other languages ?

    • Event driven and Non-Blocking, so handles concurrent connections efficiently than its counterparts.
    • It's great to have common language on both client and server.
    • Even better, if used with Databases like MongoDb, then it's 100% JavaScript, From DataBase to Server to Client.
    • Clean, Functional API.
