Angular JS Architecture from A to Z

Are you trying to choose a framework for developing web applications? Well, currently one of the best ones in the market is Angular JS. If you know HTML, TypeScript, and JavaScript, then using this framework will be very simple for you.

In order to create an application, a developer requires a platform that provides flexibility and makes work easier for him. An ideal structure simplifies coding and gives you liberty to provide any feature you want to. Let’s see how Angular JS works for you.

What is Angular JS?

Angular JS is an open-source framework developed by Google for creating web applications. It is written in TypeScript and helps you create apps using HTML and JavaScript. The former is used for creating the UI of the app while the latter is for adding functionality.

The main benefit of using a framework like Angular JS is that you don’t have to write the code from scratch. In fact, you need to provide very little coding from your end. Let’s understand how this really works for you.

The Architecture of Angular JS

The framework is built on an architecture called MVC – short for Model View Controller. Here’s how it works:

Model is the component that stores all your data. This is the data that has been input by you or your users such as IDs or names.

The View refers to the front-end or UI of the application that is visible to the users. It contains the HTML code with which you designed the app.

Controller is the actual brain controlling the two. This is where you write all the code and update the data present in the model as well as the HTML code in the view.

Basically, as the developer you need to work on the controller side. The framework is designed in a way that you have to provide very little code. Once you enter it, the framework will organize it into little buckets called modules.        This helps you distinguish the code between features and reusable chunks, making functionality simpler and more accurate. Additionally, it provides lazy loading, that makes the loading of the web app faster.

Various Elements and Features that Make Angular JS Easy to Use

The MVC model is an overview of how Angular JS works. However, it is the other features and elements that you have access to that make app development on this framework so convenient. These include:

Templates: These are elements written in HTML which have some Angular elements and attributes. When combined with the data provided in the model and code provided in the controller, it helps to provide the required view on the browser for the user.

Directives: These are HTML attributes with a prefix that help you provide the functionality to your application. You can find some built-in directives like the ng-app for initializing the application or ng-model that combines HTML with app data. You can build your own directives too.

Two-Way Data Binding: Data binding is a feature that helps you combine the data in the model with the view. Any changes in the model will affect the changes in the view. At the same time, changes made in the view also affect the model. This is why it is called two-way data binding.

Routing: This is a module that helps the browser navigate your app through a URL.

Dependency Injection: This is a software design pattern that keeps your components lean and efficient.

This now gives you a somewhat detailed view on as to how Angular JS really works. It makes your work as a developer really easy and comes free of cost. Hence, if you want to go into the depths, just check out the framework.
