Uncaught ReferenceError: require is not defined in React Vite in Production

I am having issue which says Uncaught ReferenceError: require is not defined. I am using React 18, Vite version 5. I implemented Vite to my existing React project. Everything working in dev, but when I build and deploy it into production, I am having this error. Can anyone help me with it?

I searched everywhere but no success.

Screenshot for vite.config.js

1. Importing modules

When using Vite, use the import syntax instead of require()

// const react = require('react') ❌
import react from 'react' ✅

2. Referencing assets:

Also, when including images, svgs and videos, replace the require() you used to use in create-react-app with the actual path of the asset file.

Example:

// # create-react-app
<img src={require('../media/myImage.png')} /> ❌

// # Vite
<img src="../media/myImage.png" /> ✅

3. Importing assets

Sometimes, in your code, you import the assets as modules:

import myImage from './myImage'

The same happens in Vite.

This is useful when you use path aliases, for instance, sometimes, you import the images in create-react-app like this:

<img src={require('@media/myImage.png')} />

In vite, if you wanted that, import it first at the top then use it at the bottom:

import MyImage from '@media/myImage.png'
<img src={MyImage} /> ✅
// <img src={"@media/myImage.png"} /> ❌

Summary: there's nothing called require() in vite, if you used to do that in create-react-app, it can't happen in Vite.
