What is the best strategy for migrating a large AngularJS app?

The Incremental (Hybrid) approach is usually best for large applications, allowing you to run both frameworks side-by-side using ngUpgrade while migrating feature by feature.

Can I use Angular services in my legacy AngularJS code?

Yes, this skill provides patterns for 'downgrading' Angular injectables so they can be injected into AngularJS factories and controllers.

Does this skill help with routing migration?

Absolutely. It includes detailed mapping for moving from the AngularJS $routeProvider to the modern Angular RouterModule, including route parameters and guards.

How do I handle the bootstrap process in a hybrid application?

The skill provides TypeScript templates for manual bootstrapping where the Angular module initialization triggers the AngularJS application container.

Why should I migrate to Angular instead of a full rewrite?

A migration (especially the hybrid approach) allows for continuous delivery and feature development, reducing the risk and downtime associated with 'Big Bang' rewrites.

Guides the transition from legacy AngularJS to modern Angular frameworks using hybrid strategies and incremental component rewriting.

The Angular Migration skill provides a comprehensive framework for modernizing legacy AngularJS (1.x) applications to the latest versions of Angular (2+). It facilitates various migration strategies—including 'Big Bang' rewrites and 'Incremental' hybrid approaches via ngUpgrade—to ensure continuous delivery during the transition. By offering patterns for component conversion, dependency injection updates, and routing migration, this skill helps developers reduce technical debt and implement modern frontend best practices without disrupting existing production workflows.
