Node Js training
Node Js Introduction:
Before Jumping into the conclusions of the Node JS Training in Chennai by Hope Tutors, We would have a brief glimpse on the Node JS.
Previously Client-side scripting was the main and only functionality of JavaScript. JavaScript typically is embedded in a web page’s HTML file. JavaScript runs client-side by a JavaScript engine in the client web browser. The interactive functions of your favorite websites are written in JavaScript. By 2009 Ryan Dahl invented Node.js which allowed JavaScript to be executed in the server-side too. It is used to create a server-side application of a typical client-server architecture. For a web app, the browser is the client. A machine that responds to the client request is a server. FYI: The first server-side JavaScript environment is Live Wire Pro Web from Netscape.
Node.js is built on top of the Google V8 JavaScript engine. V8 is the same engine that powers Google Chrome. The Node.js run time environment is cross-platform and hence widely used. It is open source. It will execute JavaScript code outside of a browser. Using Node.js modern-day applications are developed. These days’ companies use Node.js to create a RESTful backend API known as REST APIs. Isn’t it the right time to take up a node js course in Chennai? “Hope Tutors” training institute also provides a node js online course in Chennai.
“Although I was once reserved about recommending it for mission-critical applications, I now heartily recommend Node for even the most demanding server systems.”
-Ryan Dahl, inventor of Node.js.
Node js Features:
Typescript is popular amongst the JavaScript community. Typescript is a superset of JavaScript with optional types support. Node.js introduces “JavaScript everywhere” concept. Now applications are developed with a single programming language. Back then, client and server had different programming languages.
This led to modern full-stack application development called the MEAN stack.
“npmjs” (node package manager) website hosts a variety of open-source libraries for Node.js. Command Line tools and server-side scripting are coded using Node.js extensively. For example; Node.js can produce dynamic web page content served by server-side scripts. This content will be served before the page is sent to the user’s web browser.
Node js Concepts:
Network programs such as Web servers or REST APIs could be created using Node.js. Node.js functions are non-blocking whereas PHP functions block until completion. Non-blocking refers to the commands executing at the same time. The signal either completion or failure via callbacks. Non-blocking is also termed as Asynchronous. Blocking until completion refers to the commands that execute one after the other. Blocking code is also known as Synchronous.
Node.js architecture is event driven which is capable of asynchronous I/O. Hence the throughput is optimized along with improved scalability of the web. Real-time applications with several input/output operations are the perfect fit for Node.js with MongoDB.
An Analogy:
Apache is a multi-threaded HTTP server. It means for every single request that the server receives, a separate thread is created which would handle that request.
Whereas Node.js is an event-driven architecture. It handles all the requests asynchronously from a single thread.
The main event loop keeps running even after forwarding the request to the thread pool. It can accept more incoming requests as it does not sleep or wait. SQL queries/HTTP client requests/file system reads follows this practice. Concepts are well explained by creative teachers who are committed. Hope Tutors trainers excel in delivering node js training in Chennai.
What are the Benefits of Node JS Training in Chennai:
Corporate users of Node.js include GoDaddy, IBM, LinkedIn, Microsoft, Netflix etc. Many small to mid-tier organizations are embracing the modern Node.js runtime environment. The reason is to head start their application development process.
Some of the real-time communication programs like messengers, social media, and browser games rely on Node.js. They preferably integrate Node.js with the highly scalable “NoSQL DB” like Mongo DB.
Node.js can be combined with a browser, a database that supports JSON data (such as Postgres/ MongoDB) and JSON. This is for a unified JavaScript development stack like the trending MEAN/MERN stack. Similar to the latest features of server-side development patterns such as MVC, MVP, MVVM, etc., Node.js permits the usage/reuse of the service interface and model between the client-side code and server-side code. The ultimate benefit of taking our node js course in Chennai is you having a confident career.
Node js Frameworks:
Hapi.js, Socket.io (real-time web applications like chat applications), Express.js, Sails.js are just a few frameworks to build apps for node.js. Express.js is one of the most wanted and essential web frameworks for Node.js. It is a minimalist framework for building a host of web and mobile applications as well as APIs (REST APIs). Popular applications like MySpace, Geeklist, Klout, Segment.io, and Yummly are few powered by Express.js. Express.js offers various features like middleware, template engines, simplified multiple routing, database integration and much more. Learning is just fun again at Hope Tutors node js course in Chennai.
