What is the Angular JS?

Angular JS is a structural framework that helps in offering a completely client-side solution to develop a dynamic web application. Originally started as a project in Google, Angular JS is now an open source JavaScript MVC framework.

Angular JS is one of the most popular modern day web frameworks that the developers use HTML as their template language and extend HTML’s syntax to express the application’s components clearly and succinctly. Thus, there is no need to learn another language or syntax.

HTML is considered as a great declarative language for static documents. Angular JS works by changing static HTML to dynamic HTML. Thereby extending the ability of HTML to create custom attributes using simple JavaScript and also add built-in attributes and components

Since Angular JS maintained by Google and a community of developers, it is always up to date and is widely used to help manage and assist web applications. It is designed in a way that makes it works seamless with the new generation tools and eliminates data binding and dependency injection.

Features of Angular JS

Angular JS is an amazing feature rich JavaScript framework that allows developers to add more meaning to their client-side applications. Take a look at the overview of the features offered by Angular JS:

  • MVC Architecture

Comprises of three important elements model, view and controller, the idea behind using this architecture is to split the web application into a more manageable structure. This is because MVC makes it easier for developers to build a client-side web application.

MVC architecture is very dynamic in nature and offers the developer with the flexibility of not to write extra code to fit all the elements together. It does that automatically, all you have to do is to put the MVC element separately.

  • Two Way Data Binding

The two-way Data Binding is considered as an extraordinary feature that has ever been integrated into a JavaScript framework. In the process, any change made in the view will automatically reflect in the model and vice versa. A two-way process binds the model to the view.

  • Less Code to Write

Angular JS framework requires very less coding with no need to write separate code for MVC. Since HTML is used for building the user interface, therefore the work of data binding is reduced for moving the data manually in the view. You can complete a task with a single code set for one application.

  • Unit Testing

Unlike the traditional method, now there is no need to create a test page for testing the behaviour of the component. Thanks to Angular JS for making the testing part simple. The developers at Google have offered a testing framework “Karma”, which helps in designing unit tests for Angular JS applications.

Angular JS Architecture

Angular.js follows the dynamic MVC architecture, which is a software design pattern for developing web applications. It comprises of three important elements, the model, view and controller.

  • Model ? It is the lowest level of the pattern which contains primitive declarations, responsible for maintaining data. They are simply used to represent your data.
  • View ? It is responsible for displaying the presentation layer, which holds all or a portion of the data for the end user.
  • Controller ? It is a software Code that represents the layer that has the business logic. It controls the interactions between the Model and View, which are stored inside the controller.

What is Node JS?

Node JS is a lean, cross-platform, fast, open-source server JavaScript runtime environment that is built on Chrome’s V8 JavaScript engine. It is useful for building highly scalable server-side applications. That means one can execute Javascript code on their computer itself, using runtime rather than running it in the browser.

Node JS is developed by Ryan Dahl and came into existence in 2009. Build on Google Chrome’s V8 JavaScript Engine, the original developers of JavaScript extended it from something you could only run in the browser to something you could run on your machine as a standalone application.

Node JS is perfect for data-intensive real-time applications as it is lightweight and efficient. This is because it uses an event-driven, non-blocking I/O model that is designed to optimize an application’s throughput and scalability for real-time web applications.

Node JS offers the developer with a rich library of various JavaScript modules. These modules help in simplifying the development of web applications using Node JS largely.

Features of Node JS

Node JS now plays a critical role in the technology stack of many high-profile companies who depend on its unique features. Some of the key features that make Node JS the first choice of software architects are

  • Asynchronous and Event Driven

All APIs available in Node JS library is non-blocking, that means they are asynchronous. It typically means that a Node JS based server never waits for an API to return data, it rather moves to next API after calling the first one. A special notification mechanism of Events of Node JS helps the server to get a response from the previous API call.

  • VeryX2 Fast

Node JS is built on Google Chrome’s V8 JavaScript Engine, thus it the library is very fast in code execution.

  • Single Threaded but Highly Scalable

The model used by Node JS is a single threaded model with event looping. The mechanism of this model helps the server to respond in a non-blocking way. This makes the server highly scalable when compared to a traditional server, which creates limited threads to handle requests.

  • No Buffering

There is no buffering of any data in Node JS applications. These applications rather chunk the output data.

  • License

Node JS is an open-source framework, released under the MIT license (MIT license is a free software license originating at the Massachusetts Institute of Technology (MIT))

  • Community

Node JS is very popular and has emerged as one of most of the used technologies because it has lots of community tutorials, resources or shared code to offer.

The architecture of Node JS

Node JS is doing magical things with its “Single Threaded Event Loop Model†architecture. It is a super efficient way of handling multiple concurrent clients at once than traditional servers like Apache HTTP Server. Additionally, users of Node are free from worries of dead-locking the process since there are no locks. The process never blocks because no function in the Node directly performs I/O.

The processing Model of Node JS is based on Javascript Event based model, which enables the Javascript call back mechanism. Node JS comprises of two main components

  • Core V8 Engine: Run time Environment It is an open source JIT (Just In Time) compiler, which is written in C, C++ and outperformed PHP, Ruby and python performance wise.
  • Libuv: A C++ library NodeÂ’s Libuv library handles the NodeÂ’s asynchronous I/O operation and main event loop. This library holds thread pool reserve, which handles the thread allocation to individual I/O operations.

Conclusion Angular JS vs Node JS

According to the above comparisons, both Angular JS and Node JS looks promising and exciting option within their own domain. If given a choice to select among Angular JS and Node JS, one must keep in mind the application requirements and select the framework.

Angular JS is solely client browser-based application and is best suited for single page applications, which are dynamic and interactive in nature. Whereas, Node JS being a server-side language requires a run-time environment for applications, which are real-time data-intensive and collaborative like Google Docs or Dropbox. However, their architecture and working model is quite different but both have an extensive set of features in their kitty, which can be used to create a variety of different applications.

Despite so many differences Angular JS and Node JS have one thing in common that is both of them are open source JavaScript projects, which hold a prime motive of building an easier web application process using JavaScript.
