The Ultimate Angular Performance Checklist: 2024 Edition

 If I had to recommend just one must-read blog post for Angular developers in 2024, I'd suggest "The Ultimate Angular Performance Checklist: 2024 Edition" by Minko Gechev (who leads the Angular team at Google).

This comprehensive guide covers:

  • Angular signals and their performance benefits compared to traditional change detection
  • Zone.js-less applications and the new developer experience
  • Hybrid rendering strategies with SSR and hydration
  • Code-splitting best practices with standalone components
  • Angular's compiler optimizations and how to leverage them
  • Memory leak prevention techniques specific to Angular
  • Build-time optimizations with esbuild and the new build system
  • Practical performance measurement using Angular DevTools

What makes this post particularly valuable is that it provides concrete code examples for each optimization technique, real-world performance metrics, and guidance on when to apply each approach based on application size and complexity.
