AngularJS has taken the front-end development world by storm, and it’s no wonder why: The framework provides developers with an incredible amount of flexibility, letting them adjust components on the fly to meet the needs of their particular projects and applications. But how do you get started learning how to use AngularJS, and what are some of the most important things you should know? This quick guide will walk you through everything you need to know about AngularJS from setting up your first project to learning how to create custom directives, which let you create elements that look and behave however you want them to!
Why use AngularJS?
Speed of Developing Applications
AngularJS is a structural framework for dynamic web apps. It lets you use HTML as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly. AngularJS’s data binding and dependency injection eliminate much of the code you would otherwise have to write. And it all happens within the browser, making it an ideal partner with any server technology.
One of the most important features of AngularJS is data binding. This feature allows you to automatically update your UI when your model changes, and vice versa. This can save you a lot of time and effort when working with large applications.
Model View Controller (MVC) Framework
MVC is a software architectural pattern for implementing user interfaces. It divides a given software application into three interconnected parts, so as to separate internal representations of information from the ways information is presented to and accepted from the user.
The MVC design pattern decouples these major components allowing for efficient code reuse and parallel development.
Typically, each part (the model, view, and controller) is built to handle specific development aspects of an application.
Two-way data binding feature
AngularJS provides a two-way data binding feature that can be very useful in certain situations. For example, if you have a form that needs to be filled out by a user, you can use two-way data binding to automatically update the model as the user types. This can save a lot of time and effort on your part, as you don’t have to constantly check and update the model yourself.
Dependency Injection (DI)
AngularJS has a built-in dependency injection system that makes it easy to develop, test, and maintain applications. This is because DI helps decouple different parts of an application, which makes them more independent and easier to change. Plus, DI can improve performance by creating new instances of objects only when they’re needed.
Application Architecture Model View Presenter (MVP)
The Model View Presenter (MVP) is an architectural pattern that separates the concerns of an application into three distinct parts: the model, the view, and the presenter.
The model represents the data that will be displayed in the view. The view is responsible for displaying the data to the user. The presenter acts as a mediator between the model and view, updating the view when changes to the model occur and updating the model when changes to the view occur.
Routing using URIs
Routing is one of the most important aspects of web development, and AngularJS makes it easy. By using the ngRoute module, you can declaratively specify application routes using AngularJS markup. This results in cleaner code and a more maintainable application. Plus, it’s easy to hire angularjs developers who are familiar with this approach.
