CloudFront Static Router Function

A minimal CloudFront function for static sites.

Overview

• Routing Logic:
  • Requests without an extension are rewritten:
    • /about → /about.html
    • Unmatched cases default to /index.html
  • Requests with an extension (e.g., /sitemap.xml) remain unchanged.

Astro Configuration

To ensure proper URL rewriting, configure Astro to output files (not directories) by setting the following in your astro.config.mjs

export default defineConfig({
  build: {
    format: 'file',
  },
});
