description: Migrate from AngularJS to Angular using hybrid mode, incremental component rewriting, and dependency injection updates. Use when upgrading AngularJS applications, planning framework migrations, or modernizing legacy Angular code.

Angular Migration

Master AngularJS to Angular migration, including hybrid apps, component conversion, dependency injection changes, and routing migration.

Use this skill when

  • •Migrating AngularJS (1.x) applications to Angular (2+)
  • •Running hybrid AngularJS/Angular applications
  • •Converting directives to components
  • •Modernizing dependency injection
  • •Migrating routing systems
  • •Updating to latest Angular versions
  • •Implementing Angular best practices

Do not use this skill when

  • •You are not migrating from AngularJS to Angular
  • •The app is already on a modern Angular version
  • •You need only a small UI fix without framework changes

Instructions

  1. •Assess the AngularJS codebase, dependencies, and migration risks.
  2. •Choose a migration strategy (hybrid vs rewrite) and define milestones.
  3. •Set up ngUpgrade and migrate modules, components, and routing.
  4. •Validate with tests and plan a safe cutover.

Safety

  • •Avoid big-bang cutovers without rollback and staging validation.
  • •Keep hybrid compatibility testing during incremental migration.
