Preface
Where is AngularJS? Since AngularJS's inception, it has been deployed into a multitude of different environments, mostly due to its flexibility and extensibility. Parallel to Angular's rise are developer tools such as Apache Cordova and Chrome packaged apps. These have given developers the opportunity to deploy web applications on platforms that were previously dominated by languages such as Java and C. With these advancements, AngularJS apps can now be found in the Chrome Web Store, Google Play Store, Apple App Store, PlayStation Store, and Firefox Marketplace, all in addition to traditional in-browser web applications. To see examples of other members of the AngularJS community that are built on AngularJS, https://builtwith.angularjs.org/ is a phenomenal place. As AngularJS and its community mature, I suspect that the aforementioned question will become "Where isn't AngularJS?"
Without a talented and thriving developer community, AngularJS would not be the framework that it is today. The most apparent metric I found to measure this phenomenon is the rate at which the new versions of AngularJS are released. At its apex, it reaches 3 minor releases in 1 day and 5 minor releases per month in March 2014. To help the community and contributors keep up with the pace of development, the AngularJS core team maintains the website https://dashboard.angularjs.org/, which provides a real-time snapshot into the current build status of AngularJS's core. Because of its extensible design, contributors have also been able to enhance AngularJS's core through the development of third-party modules, services, filters, and directives. Some examples are the popular REST Angular module for consuming RESTful APIs, the Angular-UI frontend framework, Ionic Framework for mobile UIs, Firebase real-time data storage and syncing, and Yoeman generators for Angular.
