To use vite env variables in vite.config.js, you can access them through the process.env object. Here is an example of how you can use env variables in your vite.config.js file:

import { defineConfig } from 'vite'

export default defineConfig({
  base: process.env.BASE_URL || '/',
  plugins: [
    // you can also use env variables in your plugins configuration
  ],
  build: {
    outDir: process.env.OUT_DIR || 'dist'
  }
})

In this example, we are using process.env.BASE_URL and process.env.OUT_DIR to set the base URL and output directory for the build respectively. You can define your own env variables in your .env files and access them in your Vite configuration file in the same way.

Make sure to prefix your env variables with VITE_ to make them available in your Vite configuration. For example, if you have an env variable named API_URL, you should define it as VITE_API_URL in your .env files.
