Zero-Downtime Edge Deployments on Cloudflare Pages with Wrangler

Modern static site architectures eliminate origin server bottlenecks by pre-rendering HTML and serving assets directly from the global edge network.

Edge Cache Invalidation Strategy

Cloudflare Pages performs atomic directory swaps during each Wrangler deployment, ensuring clients never experience half-deployed CSS or broken asset hashes.

# Deploy production static bundle to Cloudflare Pages
npx wrangler pages deploy dist --project-name=technical-blog --branch=main

Combining Astro static generation with automatic Cloudflare Edge SSL achieves both maximum security and top Core Web Vitals scores globally.
