title: No Before Interactive Script Outside Document
|
|
---
|
|
|
|
> Prevent usage of `next/script`'s `beforeInteractive` strategy outside of `pages/_document.js`.
|
|
|
|
## Why This Error Occurred
|
|
|
|
You cannot use the `next/script` component with the `beforeInteractive` strategy outside `pages/_document.js`. That's because `beforeInteractive` strategy only works inside **`pages/_document.js`** and is designed to load scripts that are needed by the entire site (i.e. the script will load when any page in the application has been loaded server-side).
|
|
|
|
## Possible Ways to Fix It
|
|
|
|
If you want a global script, move the script inside `pages/_document.js`.
|
|
|
|
```jsx filename="pages/_document.js"
|
|
import { Html, Head, Main, NextScript } from 'next/document'
|
|
import Script from 'next/script'
|
|
|
|
export default function Document() {
|
|
return (
|
|
<Html>
|
|
<Head />
|
|
<body>
|
|
<Main />
|
|
<NextScript />
|
|
<Script
|
|
src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.20/lodash.min.js"
|
|
strategy="beforeInteractive"
|
|
></Script>
|
|
</body>
|
|
</Html>
|
|
)
|
|
}
|
|
```
