Encountering the ‘Uncaught Error: Cannot find module ‘react-dom/client\” message in your React project can be a challenging roadblock. This error typically occurs when the specified module cannot be located during the build process. Understanding the root cause and implementing the correct solutions is crucial to resolving this issue efficiently.
Let’s explore step-by-step strategies to troubleshoot and fix this error, ensuring a seamless development experience.
The error message you’re encountering, “Module not found: Error: Can’t resolve ‘react-dom/client’,” indicates that your application is unable to locate the react-dom/client module. Let’s address this issue:
React-DOM Installation:
First, ensure that you have the react-dom package installed. You can do this by running the following command in your project directory:
npm install react-dom
If you’re using Yarn, use:
yarn add react-dom
Update Your Code:
In your index.js file, replace the import statement for react-dom from:
import ReactDOM from 'react-dom/client';
to:
import ReactDOM from 'react-dom';
The correct import should be the standard react-dom package, not the specific react-dom/client module.
Re-run Your Application:
After making this change, restart your development server (e.g., npm run start) to see if the issue is resolved.

Restart Your Development Server:
npm run start
# or
yarn start
Verify Your Package Versions:
package.json lists the correct versions of React and React-DOM.npm install --save-dev @types/react-dom
# or
yarn add -D @types/react-dom
Clean the NPM Cache (Optional):
npm cache clean --force
The “Uncaught Error: Cannot find module ‘react-dom/client'” issue in React projects can be frustrating, but let’s troubleshoot it! Here are some common reasons for encountering this error and potential solutions:
Incorrect Import:
react-dom correctly. Instead of import ReactDOM from 'react-dom/client';, use import ReactDOM from 'react-dom';.React Version Compatibility:
react-dom you’re using is compatible with your React version. Sometimes, mismatched versions can cause issues.react-dom/client module is new in React 18. If you’re on an older React version (e.g., React 17), it won’t work.Webpack Configuration:
react-dom module.node_modules folder by running:
rm -rf node_modules
package-lock.json file:
rm -f package-lock.json
npm cache clean --force
npm install
Update Jest (if applicable):
package.json declaration of “workspaces” (and the package-lock.json).The error message “Uncaught Error: Cannot find module ‘react-dom/client'” can be a bit tricky, but let’s troubleshoot it together. Here are some steps you can take to resolve this issue:
Update React and react-dom:
Ensure that you are using compatible versions of React and react-dom. Sometimes, this error occurs due to version mismatches. Try upgrading both packages to the latest versions.
You mentioned using React 17, so make sure your react-dom version matches.
Remove ‘client’ from import:
In your index.js, remove the /client from the import statement for react-dom. It should look like this:
import React from 'react';
import ReactDOM from 'react-dom';
// ...
Check your dependencies:
Verify that you have installed all necessary packages correctly. Run npm install or yarn install to ensure all dependencies are up to date.
Clean up and reinstall:
Sometimes, cached files or corrupted dependencies can cause issues. Try the following steps:
node_modules folder: rm -rf node_modulespackage-lock.json: rm -f package-lock.jsonnpm cache clean --forcenpm installCheck your import paths:
Ensure that the paths in your import statements are correct. Double-check the file structure and make sure the referenced files exist.
React 18 compatibility:
If you’re using React 18 features, make sure your codebase is fully compatible. If not, consider downgrading to React 17.
In conclusion, addressing the ‘Uncaught Error: Cannot find module ‘react-dom/client\” issue demands a systematic approach and attention to detail. By verifying React and React-DOM versions, updating import statements, cleaning up dependencies, and ensuring proper webpack configurations, you can overcome this error effectively. Remember to maintain version compatibility, review import paths, and consider the nuances of React 18 if applicable.
Incorporating these strategies will help you navigate and resolve the ‘Uncaught Error: Cannot find module ‘react-dom/client\” error with confidence and elevate the performance of your React applications.
