AngularJS

AngularJS is a toolset for building the framework most suited to your application development, maintained by Google. It is fully extensible and works well with other libraries.

Note: AngularJS support has officially ended as of January 2022. Try the new Angular.

Every feature can be modified or replaced to suit your unique development workflow and feature needs. Read on to find out how. AngularJS lets you extend HTML vocabulary for your application. The resulting environment is extraordinarily expressive, readable, and quick to develop.

Other frameworks deal with HTML’s shortcomings by either abstracting away HTML, CSS, and/or JavaScript or by providing an imperative way for manipulating the DOM. Neither of these addresses the root problem that HTML was not designed for dynamic views.



Features and Highlights

Data Binding
Data-binding is an automatic way of updating the view whenever the model changes, as well as updating the model whenever the view changes. This is awesome because it eliminates DOM manipulation from the list of things you have to worry about.

Controller
Controllers are the behavior behind the DOM elements. AngularJS for PC lets you express the behavior in a clean, readable form without the usual boilerplate of updating the DOM, registering callbacks, or watching model changes.

Plain JavaScript
Unlike other frameworks, there is no need to inherit from proprietary types in order to wrap the model in accessor methods. AngularJS models are plain old JavaScript objects. This makes your code easy to test, maintain, reuse, and again free from boilerplate.

Directives
Directives are a unique and powerful feature available in AngularJS. Directives let you invent new HTML syntax, specific to your application.

Reusable Components
A component allows you to hide complex DOM structure, CSS, and behavior. This lets you focus either on what the application does or how the application looks separately.

Localization
An important part of serious apps is localization. AngularJS's locale-aware filters and stemming directives give you building blocks to make your application available in all locales.

Deep Linking
A deep link reflects where the user is in the app. This is useful so users can bookmark and email links to locations within the app. Round-trip apps get this automatically, but AJAX apps, by their nature, do not. It combines the benefits of deep linking with desktop app-like behavior.

Form Validation
Client-side form validation is an important part of a great user experience. It lets you declare the validation rules of the form without having to write JavaScript code. Write less code, go have a beer sooner.

Server Communication
It provides built-in services on top of XHR as well as various other backends using third-party libraries. Promises further simplify your code by handling the asynchronous return of data.

Injectable
The dependency injection in the app allows you to declaratively describe how your application is wired. This means that your application needs no main method, which is usually an unmaintainable mess. Dependency injection is also a core to AngularJS Desktop. This means that any component that does not fit your needs can easily be replaced.

Testable
It was designed from the ground up to be testable. It encourages behavior-view separation, comes pre-bundled with mocks, and takes full advantage of dependency injection. It also comes with the end-to-end scenario runner, which eliminates test flakiness by understanding the inner workings of AngularJS.

FAQs

What is AngularJS?
AngularJS is a JavaScript-based front-end framework originally developed by Google. It was designed to build dynamic single-page web applications (SPAs) using an MVC (Model-View-Controller) architecture and two-way data binding.

Is AngularJS still supported?
No. AngularJS officially reached end-of-life (EOL) in January 2022 and is no longer maintained or supported. It does not receive security updates, bug fixes, or new features.

Can AngularJS still be used in 2026?
Technically, yes, but it is not recommended for new projects. Since the framework is discontinued, using it in 2026 poses security and long-term maintenance risks, especially for production environments.

What should developers use instead of AngularJS?
Developers are encouraged to migrate to modern frameworks such as Angular (the actively maintained successor), React, or Vue.js. Modern Angular (2+) is a complete rewrite and continues to receive regular updates and long-term support.
