Migrating from AngularJS to Angular can be really overwhelming. How on earth do you figure out where to even begin?
I reprised a talk I gave last year for the ngPittsburgh meetup group called "Finding the Right Path from AngularJS to Angular" that goes over a decision tree you can use to determine this. Here's the recording:
You can also watch the original version from Angular Finland.
The (roughly) four paths for migrating from AngularJS to Angular are:
- Rewrite/burn everything to the ground, sometimes called a "big bang" approach
- ngUpgrade, a library from the Angular team that lets you run AngularJS and Angular side-by-side
- Hybrid Routing, which involves one frameowrk owning one route. This can be done client side with ngUpgrade or server side.
- Angular Elements, which are web components for Angular. These are like tiny frontends you can stick anywhere, including your legacy AngularJS code.
If your company needs help with migration, I offer remote migration consultations. The most popular option is a full day review where we develop a customized action plan for your migration. We look at your build process, the current state of your legacy codebase, and anticipate any barriers you may have.
