angular-migration

Migrate AngularJS to Angular using hybrid mode, incremental rewriting, and DI updates.

• Migrate AngularJS apps to Angular using hybrid mode
• Convert directives to components and controllers to components
• Update dependency injection and routing systems
• Supports gradual migration with ngUpgrade

• Use hybrid apps with ngUpgrade for interop
• Migrate features incrementally, not all at once
• Convert directives to components with @Input/@Output
• Update DI from $injector to @Inject and providers
• Modernize routing and service patterns
• Supports both AngularJS and Angular in parallel
• Maintain legacy code while introducing new features
• Use InjectionToken for backward compatibility
