The Complete Angular Evolution: From AngularJS to Zoneless Signals
🔥 From AngularJS callbacks to Signals, Zone.js to zoneless PWAs — this is the ONLY Angular evolution roadmap you'll ever need.
👇👇 OPEN FOR THE COMPLETE ROADMAP 👇👇
The Complete Angular Evolution Series covers:
✅ AngularJS → Angular 2+ → Signals (Angular 21)
✅ JWT auth + Google social login
✅ Material UI + PrimeNG (side-by-side)
✅ Storybook, theming, AOT, tree shaking
✅ Service Workers → Offline-ready PWAs
✅ Vitest unit testing (official Angular 21+)
✅ Zone.js vs. Signals (30-80% CPU gains)
