import AutoImport from "unplugin-auto-import/vite";
import unocss from 'unocss/vite'
import { presetIcons, presetAttributify, presetUno } from "unocss";
import { ElectronDevPlugin } from "./plugins/vite.electron.dev"
 
 // https://vitejs.dev/config/
export default ({ mode }: any) => {

  console.log(loadEnv(mode,process.cwd()))
  return defineConfig({
  plugins: [
    vue(),
    vueJsx(), 
    ElectronDevPlugin(),
    unocss({
     presets:[presetIcons(),presetAttributify(),presetUno()],
      rules:[
       ['flex', { display: "flex" }],
        ['red',{color:'red'}],
         [/^m-(\d+)$/, ([, d]) => ({ margin: `${Number(d) * 10}px` })],
     ],
     shortcuts: {
