# React 18 Migration | ||
|
||
Workspaces that upgrade to Nx 14 will be automatically migrated to React 18. This migration will also include an upgrade to React Router v6, if it is used in the workspace. | ||
|
||
Nx will automatically update your applications to use the new `react-dom-/client` API. | ||
|
||
From this: | ||
|
||
```typescript jsx | ||
import { StrictMode } from 'react'; | ||
import * as ReactDOM from 'react-dom'; | ||
import App from './app/app'; | ||
|
||
ReactDOM.render( | ||
<StrictMode> | ||
<App /> | ||
</StrictMode>, | ||
document.getElementById('root') | ||
); | ||
``` | ||
|
||
To this: | ||
|
||
```typescript jsx | ||
import { StrictMode } from 'react'; | ||
import * as ReactDOMClient from 'react-dom/client'; | ||
import App from './app/app'; | ||
|
||
const root = ReactDOMClient.createRoot( | ||
document.getElementById('root') as HTMLElement | ||
); | ||
|
||
root.render( | ||
<StrictMode> | ||
<App /> | ||
</StrictMode>, | ||
document.getElementById('root') | ||
); | ||
``` | ||
|
||
There might be additional changes needed for your code to be fully compatible with React 18. If you use `React.FC` type (which Nx does not use), then you will need to | ||
update your component props to include `children` explicitly. | ||
|
||
Before: | ||
|
||
```typescript jsx | ||
interface MyButtonProps { | ||
color: string; | ||
} | ||
``` | ||
|
||
After: | ||
|
||
```typescript jsx | ||
interface MyButtonProps { | ||
color: string; | ||
children?: React.ReactNode; // children is no longer implicitly provided by React.FC | ||
} | ||
``` | ||
|
||
For more information on React 18 migration, please see the [official guide](https://reactjs.org/blog/2022/03/08/react-18-upgrade-guide.html). | ||
|
||
## React Router v6 | ||
|
||
In addition to the React 18 migration, Nx will also update your workspace to React Router v6 -- assuming you use React Router v5 previously. | ||
There are breaking changes in React Router v6. Please refer to the official [v5 to v6 guide](https://reactrouter.com/docs/en/v6/upgrading/v5) for details. | ||
|
||
We highly recommend teams to upgrade their workspace to v6, but if you choose to opt out and continue to use v5, then you will need to disable React strict mode. Navigation is broken in strict mode for React Router v5 due to a transition issue. | ||
|
||
To disable strict mode, open your `main.tsx` file and remove `<Strict>` in your render function. | ||
|
||
Before: | ||
|
||
```typescript jsx | ||
root.render( | ||
<Strict> | ||
<BrowserRouter> | ||
<App /> | ||
</BrowserRouter> | ||
</Strict> | ||
); | ||
``` | ||
|
||
After (for React Router v5): | ||
|
||
```typescript jsx | ||
root.render( | ||
<BrowserRouter> | ||
<App /> | ||
</BrowserRouter> | ||
); | ||
``` |
