Stack Configuration

astro.config.mjs

// @ts-check
import mdx from '@astrojs/mdx';
import sitemap from '@astrojs/sitemap';
import { defineConfig } from 'astro/config';
import cloudflare from '@astrojs/cloudflare';
import tailwindcss from '@tailwindcss/vite';
import react from '@astrojs/react';

export default defineConfig({
  site: '{{SITE_URL}}',  // e.g. 'https://example.com'
  integrations: [
    mdx(),
    sitemap({
      filter: (page) =>
        !['/404', '/privacy', '/terms', '/shop'].some((p) => page.includes(p)),
    }),
    react(),
  ],
  adapter: cloudflare({
    platformProxy: { enabled: true },
    imageService: "compile"
  }),
  vite: {
    plugins: [tailwindcss()],
  },
});

Key notes:

site is used for canonical URLs, OG tags, sitemap, RSS
Sitemap filter excludes legal, 404, and shop pages
platformProxy: { enabled: true } gives access to Cloudflare bindings in dev
imageService: "compile" uses Astro's built-in image optimization
No separate tailwind.config or postcss.config — Tailwind 4 uses Vite plugin

tsconfig.json

wrangler.jsonc

{
  "$schema": "node_modules/wrangler/config-schema.json",
  "name": "{{PROJECT_NAME}}",
  "compatibility_date": "2025-12-05",
  "compatibility_flags": ["nodejs_compat"],
  "pages_build_output_dir": "./dist",
  "observability": { "enabled": true },
  "vars": {
    "CONTACT_EMAIL": "{{CONTACT_EMAIL}}"
  }
}

Critical: Pages does NOT support account_id or ratelimits in config. Wrangler will reject the deploy. Set account ID via env var, configure rate limiting in dashboard.

package.json scripts

{
  "scripts": {
    "dev": "astro dev",
    "build": "astro build",
    "preview": "astro build && wrangler pages dev",
    "astro": "astro",
    "deploy": "astro build && wrangler pages deploy",
    "cf-typegen": "wrangler types",
    "convert:avif": "node src/utils/convert-to-avif.js",
    "convert:avif:all": "node src/utils/convert-to-avif.js --all",
    "convert:avif:jpeg": "node src/utils/convert-to-avif.js --jpeg",
    "convert:avif:png": "node src/utils/convert-to-avif.js --png",
    "commit": "node src/utils/git-commit.js"
  }
}

Critical: bun build invokes bun's bundler, not astro's. Always use bun run build.
