使用Inquirer实现命令行修改webconf.js配置文件修改

1.webconf.js文件

 2.package.json文件

 3.startDevConf.js

import inquirer from "inquirer";
import fs from "fs";
async function selectServe() {
  try {
    const choose = await inquirer.prompt([
      {
        type: 'input',
        name: 'serve', // 选中的key
        message: '请输入要连接的后端服务：',
      }
    ])

    const server = `http://${choose.serve}.baidu.com`
    const replaceStr = `DomainServer: '${server}'`
    console.log('连接的后端服务：',replaceStr)
    let file = fs.readFileSync('./webconfig.js', 'utf-8') // 读取文件
    let proxyTarget = findProxyTarget(file) // 找到target行数据
    const newFile = file.replace(proxyTarget, replaceStr) // 替换
    fs.writeFileSync('./webconfig.js', newFile) // 写入
  } catch (error) {
    console.log(`报错了--->: ${error}`)
  }
}
function findProxyTarget(file) {
  let fileArr = file.split('\n') 
  let proxyTarget = '' 
  for (let i = 0; i < fileArr.length; i++) { 
    if (fileArr[i].includes('DomainServer:')) {
      proxyTarget = fileArr[i] 
      break
    }
  }
  return proxyTarget
}
selectServe()

4.最终效果
