[Fixed] "Uncaught ReferenceError: process is not defined" in Vite+React app. Error in path-parse module in node – Vite

The Problem:

In a Vite+React app, an error occurs when accessing ‘process.platform’ due to ‘process’ not being defined. This error is encountered in the ‘path-parse’ module and is causing issues when running the ‘npm run dev’ command.

The Solutions:

Solution 1:

Import the ‘process’ module into the main Vite configuration file, ‘vite.config.js’. Replace the existing ‘defineConfig’ function with the following:

import { defineConfig } from 'vite'
import { resolve } from 'path'

export default defineConfig({
  // Your existing config
  resolve: {
    alias: {
      // Alias the dependency to the vite-compatible version
      'path-parse': resolve('node_modules/path-parse/dist/path-parse.min.js')
    }
  },
  define: {
    'process.platform': JSON.stringify(process.platform),
    'process.env.NODE_ENV': JSON.stringify(process.env.NODE_ENV)
  }
})

This will resolve the ‘path-parse’ dependency with its Vite-compatible version and provide access to the ‘process’ module, resolving the ‘ReferenceError: process is not defined’ issue.

Solution 2: Workaround using `define`

To resolve the issue, a workaround can be implemented by modifying the define property in the Vite configuration. This workaround involves two steps:

1. For the development environment, add the following line to the define object:

   define: {
      'process.env': {},
   }
   

2. For the production environment, modify the define object as follows:

   define: {
      'process.platform': JSON.stringify(process.platform),
   }
   

This workaround will allow the Vite app to access process.platform without causing errors in both development and production environments.
