vite-vite.config.ts中环境判断

在vite中是不像webpack那样直接可以通过process.env就能获取到配置的环境的,这里我们要借助loadEnv

//.env.dev
-# 本地环境
ENV = 'development'
VITE_NODE_ENV = 'development'

// package.json
{
  "name": "vite-project",
  "version": "0.0.0",
  "scripts": {
    "dev": "vite --mode=dev"
   }
}

import { loadEnv } from 'vite'
const envResolve = (mode) => {
  if(mode.indexOf('=')!=-1){
    mode = mode.split('=')[1]
  }
  return loadEnv(mode, process.cwd());
};
const getEnv = function (env) {
  return envResolve(_.last(process.argv))[env];
}
const modes = getEnv('VITE_NODE_ENV') //development
