Should I migrate my codebase to TypeScript before starting?

Migrating your AngularJS code to TypeScript is a highly recommended preliminary step. It provides better type safety and makes the eventual transition to Angular components much more straightforward.

What is the recommended way to start an Angular migration?

The most common recommendation is an incremental hybrid approach using the UpgradeModule. Start by migrating services and utility functions first, as they have fewer UI dependencies.

Can I run AngularJS and Angular side-by-side?

Yes, using the ngUpgrade library allows both frameworks to coexist in the same application, enabling you to migrate features one by one while keeping the app functional.

How do I handle dependency injection between the two frameworks?

You can use 'downgradeInjectable' to make Angular services available to AngularJS, or use an InjectionToken with a factory to bring AngularJS services into the Angular environment.

Learning & Documentation

Modernizes legacy AngularJS applications by providing structured patterns for hybrid app setup, component conversion, and dependency injection updates.

The Angular Migration skill is a specialized guide for transitioning legacy AngularJS (1.x) projects to modern Angular (2+) frameworks. It offers detailed implementation patterns for the ngUpgrade module, allowing developers to run both frameworks simultaneously during a phased rollout. Whether you are performing a complete rewrite or an incremental feature-by-feature migration, this skill provides the code snippets and architectural best practices needed to handle complex dependency injection, routing, and form transitions safely while maintaining application stability.
