公共npm包的自动检测更新

当前我们有个问题，npm包更新后，可能业务部门感知不到，升级有延迟。
为了解决该问题，可参考如下步骤：

1. npm install npm-check-updates
2. 在pacage.json中，做如下变更：覆盖即可
   "scripts": {
   "checkv": "node .\checkUpdate.js",
   "dev": "set NODE_ENV=development && npm run checkv && YYYY",
   },

xxxx是用正则匹配出想检测更新的业务npm名称规则
YYYY是其他命令

脚本如下：

const ncu = require('npm-check-updates');
const chalk = require('chalk');
const execa = require('execa');
const ora = require('ora');

function install(packages) {

    const installer = 'npm' 
    const color = chalk.supportsColor ? '--color=always' : null;

    const npmArgs = ['install']

        .concat(packages)
        .concat(color)
        .filter(Boolean);

    console.log('');
    console.log(`$ ${chalk.green(installer)} ${chalk.green(npmArgs.join(' '))}`);
    const spinner = ora(`Installing using ${chalk.green(installer)}...`);
    spinner.enabled = true
    spinner.start();

    return execa(installer, npmArgs, {}).then(output => {
        spinner.stop();
        console.log(output.stdout);
        console.log(output.stderr);

       // return currentState;
    }).catch(err => {
        spinner.stop();
        throw err;
    });
}

ncu.run({
  upgrade:true,
  filter:"/^@teld/.*$/"
}).then(function(upgraded){
    let udpateList =[]
    for(var npmName in upgraded){
      var npmVersion = upgraded[npmName].substring(1)
      var installAgrs = npmName+'@'+npmVersion
      udpateList.push(installAgrs)
      
    }
    if(udpateList.length > 0)install(udpateList)     
})
