Debugging the Performance of 4,860 Angular Apps

on YouTube ↗28m

" summary

Scans of ~4,860 Angular sites produce concrete fixes not slogans: the average app ships ~4 MB of JavaScript, one real app hits 15 MB, and ~13% lack gzip/brotli compression. Use source map explorer to see which imports bloat bundles, remove duplicate moment locales or switch CommonJS packages to ES modules, lazy‑load features with the router, run ng update to shrink bundles, and use bundlesize.dev or a CDN to measure and deliver smaller, faster builds.
