# global\_​asset\_​url

```oobleck
string | global_asset_url
```

Global assets are kept in a directory on Shopify's server. Using global assets can be faster than loading the resource directly.

Depending on the resource type, you might need to use an additional filter to load the resource. The following table outlines which filter to use for specific resource types.

| Resource type | Additional filter |
| - | - |
| JavaScript (`.js`) | [`script_tag`](https://shopify.dev/docs/api/liquid/filters/script_tag) |
| CSS (`.css`) | [`stylesheet_tag`](https://shopify.dev/docs/api/liquid/filters/stylesheet_tag) |

The following table outlines the available global assets:
