# Angular Migration Master AngularJS to Angular migration, including hybrid apps, component conversion, dependency injection changes, and routing migration. ## When to Use This Skill - 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 ## Migration Strategies ### 1. Big Bang (Complete Rewrite) - Rewrite entire app in Angular - Parallel development - Switch over at once - **Best for:** Small apps, green field projects ### 2. Incremental (Hybrid Approach) - Run AngularJS and Angular side-by-side - Migrate feature by feature - ngUpgrade for interop - **Best for:** Large apps, continuous delivery ### 3. Vertical Slice - Migrate one feature completely - New features in Angular, maintain old in AngularJS - Gradually replace - **Best for:** Medium apps, distinct features ## Hybrid App Setup ```typescript // main.ts - Bootstrap hybrid app import { platformBrowserDynamic } from "@angular/platform-browser-dynamic"; import { UpgradeModule } from "@angular/upgrade/static"; import { AppModule } from "./app/app.module"; platformBrowserDynamic() .bootstrapModule(AppModule) .then((platformRef) => { const upgrade = platformRef.injector.get(UpgradeModule); // Bootstrap AngularJS upgrade.bootstrap(document.body, ["myAngularJSApp"], { strictD...
