AngularJS is a
JavaScript-based
open-source front-end
web framework mainly maintained by
Google and by a community of individuals and corporations to address many of the challenges encountered in developing
single-page applications. It aims 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
rich Internet applications.
AngularJS is the frontend part of the MEAN stack, consisting of MongoDB database, Express.js web application server framework, Angular.js itself, and Node.js server runtime environment. Version 1.7.x is on Long Term Support until July 1st 2021. After that date AngularJS will no longer be updated and Angular (2.0+) is suggested instead.The AngularJS framework works by first reading the Hypertext Markup Language (HTML) page, which has an additional custom HTML attributes embedded into it. Angular interprets 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 can be manually set within the code, or retrieved from static or dynamic JSON resources.
