# Url is deprecated
|
|
|
|
#### Why This Error Occurred
|
|
|
|
In versions prior to 6.x the `url` property got magically injected into every `Page` component (every page inside the `pages` directory).
|
|
|
|
The reason this is going away is that we want to make things very predictable and explicit. Having a magical url property coming out of nowhere doesn't aid that goal.
|
|
|
|
*Note:* In some cases using React Dev Tools may trigger this warning even if you do not reference `url` anywhere in your code. Try temporarily disabling the extension and see if the warning persists.
|
|
|
|
#### Possible Ways to Fix It
|
|
|
|
https://github.com/zeit/next-codemod#url-to-withrouter
|
|
|
|
Since Next 5 we provide a way to explicitly inject the Next.js router object into pages and all their decending components.
|
|
The `router` property that is injected will hold the same values as `url`, like `pathname`, `asPath`, and `query`.
|
|
|
|
Here's an example of using `withRouter`:
|
|
|
|
```js
|
|
import { withRouter } from 'next/router'
|
|
|
|
class Page extends React.Component {
|
|
render() {
|
|
const {router} = this.props
|
|
console.log(router)
|
|
return <div>{router.pathname}</div>
|
|
}
|
|
}
|
|
|
|
export default withRouter(Page)
|
|
```
|
|
|
|
We provide a codemod (a code to code transformation) to automatically change the `url` property usages to `withRouter`.
|
|
|
