# Asset Caching

{% hint style="danger" %}
Contains a breaking change compared to v1.0.x
{% endhint %}

The cache is populated with all assets managed by Asset Mapper. By default, it includes all types of well recognized assets such as images, stylesheets or scripts:

```regex
/\.(css|js|json|xml|txt|map|ico|png|jpe?g|gif|svg|webp|bmp)$/
```

This can be changed using the next configuration options:

{% code title="/config/packages/pwa.yaml" lineNumbers="true" %}

```yaml
pwa:
    serviceworker:
        enabled: true
        src: "sw.js"
        workbox:
            asset_cache:
                enabled: true
                regex: '/\.(css|jsx?)$/'
```

{% endcode %}
