title: No Sync Scripts
|
|
---
|
|
|
|
> Prevent synchronous scripts.
|
|
|
|
## Why This Error Occurred
|
|
|
|
A synchronous script was used which can impact your webpage performance.
|
|
|
|
## Possible Ways to Fix It
|
|
|
|
### Script component (recommended)
|
|
|
|
```jsx filename="pages/index.js"
|
|
import Script from 'next/script'
|
|
|
|
function Home() {
|
|
return (
|
|
<div class="container">
|
|
<Script src="https://third-party-script.js"></Script>
|
|
<div>Home Page</div>
|
|
</div>
|
|
)
|
|
}
|
|
|
|
export default Home
|
|
```
|
|
|
|
### Use `async` or `defer`
|
|
|
|
```html
|
|
<script src="https://third-party-script.js" async />
|
|
<script src="https://third-party-script.js" defer />
|
|
```
