AngularJS\u00a0is a discontinued\u00a0free and open-source\u00a0JavaScript<\/a>-based\u00a0web framework<\/a>\u00a0for developing\u00a0single-page applications<\/a>. It was maintained mainly by\u00a0Google\u00a0and a community of individuals and corporations. It aimed to simplify both the development and the\u00a0testing\u00a0of such applications by providing a framework for client-side\u00a0model\u2013view\u2013controller<\/a>\u00a0(MVC) and\u00a0model\u2013view\u2013viewmodel<\/a>\u00a0(MVVM) architectures, along with components commonly used in\u00a0web applications\u00a0and\u00a0progressive web applications.<\/p>\n

AngularJS was used as the frontend of the\u00a0MEAN<\/a>\u00a0stack, that consisted of\u00a0MongoDB<\/a>\u00a0database,\u00a0Express.js<\/a>\u00a0web application server framework, AngularJS itself (or\u00a0Angular<\/a>), and\u00a0Node.js<\/a>\u00a0server runtime environment.<\/p>\n

As of January 1, 2022, Google no longer updates AngularJS to fix security, browser compatibility, or\u00a0jQuery<\/a>\u00a0issues. The Angular team recommends upgrading to\u00a0Angular (v2+)<\/a>\u00a0as the best path forward, but they also provided some other options.<\/p>\n

The AngularJS framework worked by first reading the HyperText Markup Language (HTML) page, which had additional custom HTML attributes embedded into it. 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 values of those JavaScript variables could be manually set within the code or retrieved from static or dynamic JSON resources.<\/p>\n

AngularJS 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. 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. As a result, AngularJS de-emphasized explicit Document Object Model (DOM) manipulation with the goal of improving testability and performance.<\/p>\n

AngularJS’s design goals included:<\/p>\n
