What is Nodejs and AngularJS? What are the uses of Nodejs and AngularJS?

What is Node JS?

Nodejs is a cross-platform runtime library and environment for running JavaScript app outside the browser. This is a free and open source tool worked for creating server-side JS applications.

Nodejs development services or applications are written in JavaScript. This app can runs within the Nodejs runtime on Linux and Microsoft Windows. This framework offers a rich library of various JavaScript modules to simplify the web development process. Nodejs will be helpful in situations when something active and more scalable is required.

Features of Nodejs:

Some of the important features that make Nodejs the primary choice of software engineers.

Asynchronous and Event Driven:

All APIs of Nodejs library is asynchronous, That is nonblocking. It actually means a Nodejs based server nevermore idles for an API to return data. The server runs to the next API after calling it including a notification mechanism of Events of Nodejs supports the server to get a response from the previous API call.

Very Fast:

Continuing built on Google Chrome's V8 JavaScript Engine, Nodejs library is so fast in code performance.

Single Threaded but Highly Scalable:

Nodejs works on a single threaded model including event looping. Event mechanism supports the server to respond in a nonblocking way and performs the server highly scalable as opposed to traditional servers which perform limited threads to handle requests. Nodejs works a single threaded program and the same program can provide service to an extremely extensive number of requests than usual servers like Apache HTTP Server.

No Buffering:

Nodejs app never buffers any data. These apps simply output the data in chunks.

What is Angular JS?

AngularJS is a basic framework for developing dynamic web applications. This allows developers to do HTML as the template language and lets HTML's syntax to show the application's segments briefly but clearly.

This is a full-featured JavaScript framework, including the initial goal of simplification. It presents support for developing dynamic, single page web applications and supports the programming structure. AngularJS development services. AngularJS is valuable in creating real-time apps like instant messaging or chat apps.

Features of AngularJS:

AngularJS holds a lot of fame is its unique features. The features perform application development comfortable and result very intuitive. These features include,

Two-way data-binding:

Data binding is one of the main important AngularJS features. This feature supports to save the developer from creating a lot of coding. In any application, 75% of the code base is committed to manipulating, traversing, and also listening to DOM. But data-binding in AngularJS benefits to reduce the work so that the developer can focus on the application.

Ready to use templates:

The AngularJS is naturally plain HTML. The browser parses those templates into the DOM and transforms it to AngularJS compiler. Then this AngularJS Framework crosses the templates to get rendering instructions named directives. The ability to use templates performs it easy even for people with little computing skills come up with excellent applications.

Dependency injection:

This is a primary feature in AngularJS that executes the developer able to ask for dependencies essentially opposed to executing them on his own.

Testing feature:

Individual AngularJS developer or team worked with particular focus on testability in mind. This means that you can easily test AngularJS applications.

Conclusion:

Nodejs is a cross-platform runtime library and environment for running JavaScript apps outside the browser. Nodejs allows a rich library of different JavaScript modules which can simplify coding. AngularJS is a basic framework for developing dynamic web apps. The purpose of the AngularJS framework is to provide a reduced development process. Nodejs is Excellent for developing base projects. While Angular JS is an excellent choice for long size projects. Both Nodejs and AngularJS platforms are targeted at building web apps using JavaScript. But both of them are separate in their architecture and working.
