Questions tagged [angularjs]

Use for questions about AngularJS (1.x), the open-source JavaScript framework. Do NOT use this tag for Angular 2 or later versions; instead, use the [angular] tag.

AngularJS is an open-source JavaScript framework for building CRUD-centric Ajax-style web applications. Its goal is to shim the browser to augment the HTML vocabulary with directives useful for building dynamic web applications.

AngularJS ships with directives which add two-way data binding, DOM control and unrolling, code-behind DOM, form validation, and deep linking.

Initially released in 2009, AngularJS was developed and maintained by Google, and is used internally by Google in 1600+ applications.

Note: AngularJS refers to all 1.x versions of the framework, while Version 2 and higher are referred to now as "Angular" (see It's just Angular). The [tag: angular] tag should only be used for questions pertaining to versions 2 and higher.

AngularJS's Philosophy

  • Encourages developers to create their own directives, turning the HTML into a DSL suited to building their kind of application. The result significantly reduces the amount and complexity of JavaScript needed to build web applications.
  • UI is best described in the declarative form (HTML), and that behavior is best described in an imperative form (JavaScript) and that the two should never meet.
  • Encourages developers to design their client architecture using advanced software principles like dependency injection (DI), separation of concerns (SoC), testability, and a file structure.

Notable features

  • Teach your browser new tricks by adding behavior to HTML tags/attributes
  • Controllers provide code-behind DOM with clear separation from the view
  • Two-way data binding without the need to extend or wrap the model objects
  • Dependency injection assembles the application without 'main' method
  • Promises/futures remove many callbacks from code when communicating with the server
  • Directives
  • Views and routes
  • Filters
  • Form validation
  • Strong focus on testability
  • Extend HTML with your own behavior
  • Angular uses spinal-case for its custom attributes and camelCase for the corresponding directives which implement them
