AngularJS has evolved into a solid framework that is well-suited for modernizing legacy web apps. Enhancing a legacy web app with AngularJS can be done step by step and thus with bypassing the risks of a rewrite. Especially for large-scale apps, iterative enhancement and replacement are generally preferred. This talk describes the integration of AngularJS at Mercateo, where AngularJS is used to improve a front end mostly consisting of server-side rendered HTML, jQuery code and some GWT parts. I will highlight the rationale behind choosing AngularJS over other web frameworks and will walk through problems we encountered and our solutions, for example reasonable use cases of ng-init outside of ng-repeat. Having used AngularJS within our application landscape for some time, we can conclude that it help us to react faster to business needs while providing a better user experience and cleaner code.
