This bundle adds the twig function manifest_asset that is a wrapper for the native asset but looks for a configured manifest json file to map assets. This file can be generated using Gulp and the gulp-rev Gulp plugin. If you have used Laravel with Laravel Elixir the manifest_asset function is similar to Laravel's elixir function.



composer require zenstruck/asset-manifest-bundle

Enabled bundle:

  public function registerBundles() {
      $bundles = [
          new Zenstruck\AssetManifestBundle\ZenstruckAssetManifestBundle(),


By default, no manifest is configured. In development, this is probably ideal. For production, you will want to configure a manifest file to map your assets.


    manifest_file: "%kernel.root_dir%/../web/assets/manifest.json"



asset should be replaced by manifest_asset in twig files.

Here an example:

<!DOCTYPE html>
    <title>My page title</title>
    <meta charset="utf-8">
    <link rel="stylesheet" href="{{ manifest_asset('assets/main.css') }}">
    My page content

Note: If no manifest file is configured, the manifest_asset behaves exactly like the native asset function.


Say your public (web) folder looks as follows:

├── assets
│   ├── build
│   │   ├── css
│   │   │   └── app-8f07f52635.css
│   │   └── rev-manifest.json
│   └── css
│       └── app.css

And your rev-manifest.json file looks as follows:

    "css/app.css": "css/app-8f07f52635.css"

Using the manifest_asset twig function, you would pass assets/css/app.css but this wouldn't map correctly. To fix this, you can add prefixes to your config.yml:

    manifest_file: "%kernel.root_dir%/../web/assets/build/manifest.json"
        source: assets/
        destination: assets/build/

Now, assets/css/app.css would properly map to assets/build/css/app-8f07f52635.css.
