title: Minimum React Version
|
|
---
|
|
|
|
## Why This Error Occurred
|
|
|
|
Your project is using an old version of `react` or `react-dom` that does not
|
|
meet the suggested minimum version requirement.
|
|
|
|
Next.js suggests using, at a minimum, `react@18.2.0` and `react-dom@18.2.0`.
|
|
Older versions of `react` and `react-dom` do work with Next.js, however, they do
|
|
not enable all of Next.js' features.
|
|
|
|
For example, the following features are not enabled with old React versions:
|
|
|
|
- [Fast Refresh](/docs/architecture/fast-refresh): instantly
|
|
view edits to your app without losing component state
|
|
- Component stack trace in development: see the component tree that lead up to
|
|
an error
|
|
- Hydration mismatch warnings: trace down discrepancies in your React tree that
|
|
cause performance problems
|
|
|
|
This list is not exhaustive, but illustrative in the value of upgrading React!
|
|
|
|
## Possible Ways to Fix It
|
|
|
|
**Via npm**
|
|
|
|
```bash filename="Terminal"
|
|
npm upgrade react@latest react-dom@latest
|
|
```
|
|
|
|
**Via Yarn**
|
|
|
|
```bash filename="Terminal"
|
|
yarn add react@latest react-dom@latest
|
|
```
|
|
|
|
**Manually** Open your `package.json` and upgrade `react` and `react-dom`:
|
|
|
|
```json filename="package.json"
|
|
{
|
|
"dependencies": {
|
|
"react": "^18.2.0",
|
|
"react-dom": "^18.2.0"
|
|
}
|
|
}
|
|
```
