1. Register the bundle in your config/bundles.php file:

return [
    // ...
    Kocal\BiomeJsBundle\KocalBiomeJsBundle::class => ['dev' => true],
];

1. Create the configuration file config/packages/kocal_biome_js.yaml:

when@dev:
    kocal_biome_js:
        # The Biome.js CLI version to use, that you can find at https://github.com/biomejs/biome/tags:
        # - for >=2.0.0 versions, the git tag follows the pattern "@biomejs/biome@<binary_version>"
        # - for <2.0.0 versions, the git tag follows the pattern "cli/v<binary_version>"
        binary_version: '2.0.0'

1. Create the recommended biome.json file at the root of your project:

{
    "files": {
        "includes": [
            "**",
            "!assets/vendor/*",
            "!assets/controllers.json",
            "!public/assets/*",
            "!public/bundles/*",
            "!var/*",
            "!vendor/*",
            "!composer.json",
            "!package.json"
        ]
    }
}

In you use Biome.js <2.0.0, you can use the following configuration instead:

{
    "files": {
        "ignore": [
            "assets/vendor/*",
            "assets/controllers.json",
            "public/assets/*",
            "public/bundles/*",
            "var/*",
            "vendor/*",
            "composer.json",
            "package.json"
        ]
    }
}
