This article introduces to you a summary of the methods of packaging Vue projects by environment. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

When we develop projects, we use vue-cli 2.x version to create new projects. There are only two development environments: dev and pro. Sometimes we need a test environment for testing, so we have found many methods. Summary Here is the simplest method for everyone to use

1. package.json

Add a test running command under build

2. prod.env.js

Modify the code in config -> prod.env.js

  'use strict'
  // 读取系统运行时候的变量
  const target = process.env.npm_lifecycle_event;
  // 控制台日志输出
  console.log('env is deploying, current env is', target)
  // 判断环境变量，是test，还是build
  if (target == 'test') {
    var obj = {
      NODE_ENV: '"production"',
      API_ROOT: '"此处替换为测试环境地址"',
    }
  } else {
    var obj = {
      NODE_ENV: '"production"',
      API_ROOT: '"此处替换为测试环境地址"',
    }
  }
    
  module.exports = obj;

3. Test environment:

$ npm run test

正式环境: 
"
$ npm run build
"
