Can I migrate services before components?

Yes, migrating services first is a recommended best practice. Services are typically easier to convert and can be shared across both frameworks using downgrading or upgrading techniques.

What is the hybrid approach in Angular migration?

The hybrid approach uses the ngUpgrade module to run AngularJS and modern Angular side-by-side, allowing developers to migrate features incrementally without a total rewrite.

What is the best way to handle dependency injection during migration?

It uses the downgradeInjectable utility to make Angular services available to AngularJS and uses factory providers to inject AngularJS services into modern Angular components.

How does this skill handle routing migration?

The skill provides specific patterns and code examples for transitioning from AngularJS ngRoute or ui-router to the modern Angular RouterModule, including state management updates.
