# `useHeadSafe`
|
|
|
|
The `useHeadSafe` composable is a wrapper around the [`useHead`](/docs/api/composables/use-head) composable that restricts the input to only allow safe values.
|
|
|
|
## Usage
|
|
|
|
You can pass all the same values as [`useHead`](/docs/api/composables/use-head)
|
|
|
|
```ts
|
|
useHeadSafe({
|
|
script: [
|
|
{ id: 'xss-script', innerHTML: 'alert("xss")' }
|
|
],
|
|
meta: [
|
|
{ 'http-equiv': 'refresh', content: '0;javascript:alert(1)' }
|
|
]
|
|
})
|
|
// Will safely generate
|
|
// <script id="xss-script"></script>
|
|
// <meta content="0;javascript:alert(1)">
|
|
```
|
|

|
## Type
|
|
|
|
```ts
|
|
useHeadSafe(input: MaybeComputedRef<HeadSafe>): void
|
|
```
|
|
|
|
The whitelist of safe values is:
|
|
|
|
```ts
|
|
export default {
|
|
htmlAttrs: ['id', 'class', 'lang', 'dir'],
|
|
bodyAttrs: ['id', 'class'],
|
|
meta: ['id', 'name', 'property', 'charset', 'content'],
|
|
noscript: ['id', 'textContent'],
|
|
script: ['id', 'type', 'textContent'],
|
|
link: ['id', 'color', 'crossorigin', 'fetchpriority', 'href', 'hreflang', 'imagesrcset', 'imagesizes', 'integrity', 'media', 'referrerpolicy', 'rel', 'sizes', 'type'],
|
|
}
|
|
```
|
|
