Solve - Module not found: Can't resolve 'react-dom' error #

To solve the error "Module not found: Error: Can't resolve 'react-dom'", make sure to install the react-dom package by opening your terminal in your project's root directory and running the command npm install react-dom react and restart your development server.

Open your terminal in your project's root directory (where your package.json file is located) and run the following commands:

shell

Copied!
# 👇️ with NPM
npm install react-dom react

# 👇️ ONLY If you use TypeScript
npm install --save-dev @types/react-dom @types/react

# ----------------------------------------------

# 👇️ with YARN
yarn add react-dom react

# 👇️ ONLY If you use TypeScript
yarn add @types/react-dom @types/react --dev

The command will add the react-dom package to the dependencies of your project.

Make sure to restart your development server and your IDE if necessary. Your dev server won't pick up the changes until you stop it and re-run the npm start command.

You should now be able to import and use the react-dom package in your React.js app.

index.js

Copied!
import {StrictMode} from 'react';
import {createRoot} from 'react-dom/client';

import App from './App';

// 👇️ IMPORTANT: use correct ID of your root element
// this is the ID of the div in your index.html file
const rootElement = document.getElementById('root');
const root = createRoot(rootElement);

root.render(
  <StrictMode>
    <App />
  </StrictMode>,
);

If the error is not resolved, try to delete your node_modules and package-lock.json (not package.json) files, re-run npm install and restart your IDE.

shell

Copied!
# 👇️ delete node_modules and package-lock.json
rm -rf node_modules
rm -f package-lock.json

# 👇️ clean npm cache
npm cache clean --force

npm install

Make sure to restart your IDE and dev server if the error still persists. VSCode often glitches and a reboot solves things sometimes.

If you're still getting the "Module not found: Error: Can't resolve 'react-dom'" error, open your package.json file and make sure it contains the react-dom package in the dependencies object.

package.json

Copied!
{
  // ... rest
  "dependencies": {
    "react": "^18.0.0",
    "react-dom": "^18.0.0",
  },
  // 👇️ Only if you use TypeScript
  "devDependencies": {
    "@types/react": "^17.0.43",
    "@types/react-dom": "^17.0.14",
  }
}

The react-dom module should NOT be globally installed or be in your project's devDependencies, it should be in the dependencies object in your package.json file.

You can try to manually add the lines and re-run npm install.

shell

Copied!
npm install

Or install the latest version of the package:

shell

Copied!
npm install react-dom@latest react@latest

# 👇️ ONLY If you use TypeScript
npm install --save-dev @types/react-dom@latest @types/react@latest
