React Vite Error on Production Build: “jsxs” is not exported by “node_modules/react/jsx-runtime.js”

Are you tired of banging your head against the wall trying to figure out why your React app is throwing the dreaded “jsxs” error on production build? Worry no more, dear developer! In this article, we’ll dive into the potential causes and solutions to this pesky issue.

What is the “jsxs” error?

The “jsxs” error typically occurs when you’re trying to build your React application for production using Vite, and React’s JSX runtime is not properly exported. This error can be frustrating, especially if you’re new to React or Vite. But don’t worry, it’s a common issue that can be resolved with a few tweaks.

Causes of the “jsxs” error

Before we dive into the solutions, let’s explore the possible causes of this error:

• Incompatible React version: If you’re using an older version of React that’s not compatible with Vite, you might encounter this error.
• Missing or incorrect JSX runtime: The JSX runtime is responsible for converting JSX syntax into JavaScript. If it’s not properly exported or missing, the “jsxs” error will occur.
• vite.config.js configuration issues: Improper configuration in your vite.config.js file can lead to this error.
• Plugin conflicts: Conflicting plugins or libraries can cause issues with the JSX runtime.

Solutions to the “jsxs” error

Now that we’ve covered the potential causes, let’s explore the solutions:

Solution 1: Upgrade React to a compatible version

If you’re using an older version of React, try upgrading to a version that’s compatible with Vite. You can check the official React documentation for the recommended version.

npm install react@latest react-dom@latest

Solution 2: Ensure the correct JSX runtime export

Make sure that the JSX runtime is properly exported in your application. You can do this by adding the following code to your vite.config.js file:

import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';

export default defineConfig({
  plugins: [react()],
});

Solution 3: Configure vite.config.js correctly

Double-check your vite.config.js file for any configuration issues. Ensure that the build and production settings are correct.

import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';

export default defineConfig({
  build: {
    sourcemap: true,
    minify: 'esbuild',
  },
  plugins: [react()],
});

Solution 4: Resolve plugin conflicts

If you’re using multiple plugins or libraries, try resolving any conflicts that might be causing the “jsxs” error. You can do this by:

• Disabling plugins one by one to identify the culprit
• Updating plugins to their latest versions
• Removing unnecessary plugins or libraries

Solution 5: Use the `jsxRuntime` option

You can try setting the `jsxRuntime` option to `classic` or `automatic` in your vite.config.js file:

import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';

export default defineConfig({
  plugins: [
    react({
      jsxRuntime: 'classic', // or 'automatic'
    }),
  ],
});

Additional Troubleshooting Tips

If none of the above solutions work, here are some additional troubleshooting tips to help you resolve the “jsxs” error:

• Delete node_modules and reinstall: Try deleting the node_modules folder and running `npm install` or `yarn install` again.
• Check for conflicting dependencies: Verify that there are no conflicting dependencies in your package.json file.
• Review your code for syntax errors: Ensure that there are no syntax errors in your code that might be causing the error.
• Try building with the `–mode` flag: Run `npx vite build –mode production` to see if the error occurs in production mode.
