title: No Document Import in Page
|
|
---
|
|
|
|
> Prevent importing `next/document` outside of `pages/_document.js`.
|
|
|
|
## Why This Error Occurred
|
|
|
|
`next/document` was imported in a page outside of `pages/_document.js` (or `pages/_document.tsx` if you are using TypeScript). This can cause unexpected issues in your application.
|
|
|
|
## Possible Ways to Fix It
|
|
|
|
Only import and use `next/document` within `pages/_document.js` (or `pages/_document.tsx`) to override the default `Document` component:
|
|
|
|
```jsx filename="pages/_document.js"
|
|
import Document, { Html, Head, Main, NextScript } from 'next/document'
|
|
|
|
class MyDocument extends Document {
|
|
//...
|
|
}
|
|
|
|
export default MyDocument
|
|
```
