To bundle a CommonJS module in Vite, you can use the rollup-plugin-commonjs plugin along with the Vite bundler. Here's a step-by-step guide on how to do it:

  1. Install the rollup-plugin-commonjs plugin by running the following command in your project directory:
1
npm install rollup-plugin-commonjs --save-dev


  1. Import the rollup-plugin-commonjs plugin in your Vite configuration file (vite.config.js):
1
2
3
4
5
6
import { defineConfig } from 'vite'
import commonjs from 'rollup-plugin-commonjs'

export default defineConfig({
  plugins: [commonjs()]
})


  1. Update your Vite config file to specify the CommonJS module you want to include in the bundle. For example:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
import { defineConfig } from 'vite'
import commonjs from 'rollup-plugin-commonjs'

export default defineConfig({
  plugins: [
    commonjs({
      include: 'node_modules/**',
      namedExports: {
        'some-commonjs-module': ['exportedFunction1', 'exportedFunction2']
      }
    })
  ]
})


Replace 'some-commonjs-module' with the name of the CommonJS module you want to bundle, and list the exported functions that you want to include in the bundle.

  1. Run Vite to build the bundle including the CommonJS module:
1
npx vite build


After following these steps, your CommonJS module should be bundled with Vite using the rollup-plugin-commonjs plugin.
