Using a CDN

If you want to deploy your static resources (js/images) on a CDN some additional settings will have to be put in place.

Setup Vite

The base option of vite's config will need to be adjusted to point to your CDN.

// vite.config.js
export default defineConfig({
   plugins: [
     symfonyPlugin(),
   ],

   base: 'http://cdn.your-cdn-provider.com', 
});

Add integrity attributes

If the domain of your CDN is different from the domain hosting your site you will need to configure vite-plugin-symfony to support integrity hashes.

// vite.config.js
export default defineConfig({
   plugins: [
     symfonyPlugin({
       sriAlgorithm: "sha256"
     }),
   ],
});

# config/packages/pentatrion_vite.yaml
pentatrion_vite:
    crossorigin: anonymous

Tips

By following this configuration your public/build/entrypoints.json file will be correctly configured to point to your CDN files.

{
  "base": "http://cdn.your-cdn-provider.com/",

  "entryPoints": {

    "app": {
      "assets": [],
      "css": [],
      "js": ["http://cdn.your-cdn-provider.com/assets/app-dc399f15.js"],
      "legacy": false,
      "preload": []
    }
  },
  "legacy": false,
  "metadatas": {
    "http://cdn.your-cdn-provider.com/assets/app-dc399f15.js": {
      "hash": "sha256-k/0PccRNhijyiBqBUXa8Uw3GQdPxOk1iPIfqarKGEY0="
    }
  },
  "version": "6.0.0",
  "viteServer": null,
}

You will then be able to deploy the contents of your public/build folder on your CDN.

WARNING

The file generation step must always be performed on your server because it is the public/build/entrypoints.json file which is hosted on your site and not the http://cdn.your-cdn-provider.com/entrypoints.json file which will be used for integrity hashes.

TIP

Consider adding the Access-Control-Allow-Origin header in your CDN's HTTP responses.
