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"
}
}
```
