Angular Build Optimization: Budgets, Caching, and Versioning
Improve load performance with build optimization, caching rules, and safe deployment patterns.
A professional deployment is not just 'ng build'. It includes: - caching strategy - cache busting - performance budgets ## Cache busting (Angular already helps) Angular outputs hashed filenames like: `main.8f3a2c.js` That means you can cache JS for a long time safely. ## Recommended caching strategy - HTML: short cache (or no-cache), because it changes and points to new bundles - JS/CSS assets: long cache because filenames are hashed ## Budgets (prevent bundle bloat) In `angular.json`, budgets can warn if bundles get too big. This protects performance as the app grows. ## Versioning tip Show app version in UI (footer or about page) so QA can verify deployments quickly. > Next: Error handling at scale, global error handler and logging.
