When the condition is false, the element is removed from the DOM.

ng-if Basic if statement directive that instantiates the following element if the conditions are true. ng-controller Specifies a JavaScript controller class that evaluates HTML expressions. ng-class Conditionally apply a class, depending on the value of a boolean expression. Any change to the variable ‘name’ in the application's scope reflect instantly in the DOM. For example, displays the value of ‘name’ inside the span element. ng-bind Sets the text of a DOM element to the value of an expression. ng-aria A module for accessibility support of common ARIA attributes. Ng-app Declares the root element of an AngularJS application, under which directives can be used to declare bindings and define behavior. For example, both ng-app and data-ng-app are valid in AngularJS. Since ng-* attributes are not valid in HTML specifications, data-ng-* can also be used as a prefix. Ng-animate A module provides support for JavaScript, CSS3 transition and CSS3 keyframe animation hooks within existing core and custom directives. Some of the most commonly used directives were: Compilation of the directives that decorate the DOMĪngularJS directives allowed the developer to specify custom and reusable HTML-like elements and attributes that define data bindings and the behavior of presentation components.

The task performed by the AngularJS bootstrapper occurred in three phases after the DOM has been loaded: The scope behaves as a glue and binds the 'View' and the 'Controller'. Īs a part of the 'MVC' architecture, the scope forms the 'Model', and all variables defined in the scope can be accessed by the 'View' as well as the 'Controller'. The ECMA-262 specification defines scope as: a lexical environment in which a Function object is executed in client-side web scripts akin to how scope is defined in lambda calculus. Scope in computer science describes when in the program a particular binding is valid. Consequently, much of the burden on the server could be reduced.ĪngularJS used the term 'scope' in a manner akin to the fundamentals of computer science. Using dependency injection, Angular brought traditionally server-side services, such as view-dependent controllers, to client-side web applications.

to provide structure for the journey of building an application: from designing the UI, through writing the business logic, to testing.ĪngularJS implemented the MVC pattern to separate presentation, data, and logic components.

This allows development work to progress in parallel and allows for reuse of both sides.

to decouple the client side of an application from the server-side.

The difficulty of this is dramatically affected by the way the code is structured.

to decouple DOM manipulation from application logic.

As a result, AngularJS de-emphasized explicit Document Object Model (DOM) manipulation with the goal of improving testability and performance. The framework adapted and extended traditional HTML to present dynamic content through two-way data-binding that allowed for the automatic synchronization of models and views.

The values of those JavaScript variables could be manually set within the code or retrieved from static or dynamic JSON resources.ĪngularJS was built on the belief that declarative programming should be used to create user interfaces and connect software components, while imperative programming was better suited to defining an application's business logic. Angular interpreted those attributes as directives to bind input or output parts of the page to a model that is represented by standard JavaScript variables. The AngularJS framework worked by first reading the HyperText Markup Language (HTML) page, which had additional custom HTML attributes embedded into it. The Angular team recommends upgrading to Angular (v2+) as the best path forward, but they also provided some other options. It aimed to simplify both the development and the testing of such applications by providing a framework for client-side model–view–controller (MVC) and model–view–viewmodel (MVVM) architectures, along with components commonly used in web applications and progressive web applications.ĪngularJS was used as the frontend of the MEAN stack, that consisted of MongoDB database, Express.js web application server framework, AngularJS itself (or Angular), and Node.js server runtime environment.Īs of January 1, 2022, Google no longer updates AngularJS to fix security, browser compatibility, or jQuery issues. It was maintained mainly by Google and a community of individuals and corporations.
