Part 61: Performance Optimization: Purging, Bundle Size & Minification
How Tailwind produces microscopic production stylesheets and delivers 100/100 Google Lighthouse scores.
1. How Purging (Tree-Shaking) Works
Because Tailwind's JIT scanner reads your template files at build time: - If a class is never mentioned in your HTML or JS files, it is never generated. - A typical production stylesheet for an entire multi-page application is usually between 8kB and 15kB gzipped!
2. Production Checklist
- Verify
contentpaths intailwind.config.jscover all source files. - Avoid dynamic class string concatenations.
- Enable Gzip or Brotli compression on your web server (Nginx/Cloudflare).
Key Takeaways
- Tailwind's JIT ensures that production CSS stays tiny and lightning-fast.
