![]() Many developers will have their first opportunity to dig in when they tackle migrating an existing Angular 1 app to Angular 2. UpgradeĪngular 2 is a powerful and attractive platform. There will not be an Angular 3 instead, Angular 4 will be the next major release in order to correlate to version 4 of the Angular router. This means that unlike Angular 1, there will no longer be breaking changes in point releases. Note: Angular 2+ uses SemVer (Semantic Versioning). Angular 1 is still being maintained under the "AngularJS" moniker and Angular 1 apps are not about to go away. Many of us have Angular 1 apps in development or maintenance and aren't in a position to migrate them to Angular 2 due to tight deadlines, budget constraints, client or management reluctance, etc. While Angular developers were and are eager to try Angular 2+, adoption can be challenging. Angular developers knew this was coming and that Angular 2 was a full rewrite and platform implementation, not an incremental update. In mid-September 2016, Angular 2 was released after a lengthy period of betas and release candidates. There are thousands of production sites and apps built with Google's "superheroic MVW framework" and many more still in development. AngularJS 1 and Angular 2+ĪngularJS 1.x has been a frontrunner among JavaScript frameworks over the past few years. The final code for our Angular 2+ app can be cloned from the ng2-dinos GitHub repo. After this tutorial, you should be prepared to tackle your own migrations as well as new Angular 2+ projects. Learn how to migrate a real-world AngularJS app to a fresh Angular 2+ build: what's the same, what's similar, and what's completely different. ![]() TL DR: Many AngularJS 1.x developers are interested in Angular 2+, but the major differences between versions 1 and 2+ are daunting when we have so many AngularJS 1 apps already in production or maintenance. This migration article will continue to use "Angular 1" to refer to AngularJS (1.x) and "Angular 2" to refer to Angular (2 and up) in order to clearly differentiate the frameworks and reduce confusion. The Branding Guidelines for Angular state that version 1.x should be referred to as AngularJS, whereas all releases from version 2 and up are named Angular.
