Angular 使用node-schedule 实现前端定时，周期执行代码

https://www.npmjs/package/node-schedule

首先安装依赖

npm install node-schedule
npm install @types/node-schedule

引入模块

import * as schedule from 'node-schedule';

这种就是定时执行

   schedule.scheduleJob(new Date(2022,0,19,21,19,30),()=>{
      console.log('success');
    });

这种就是周期执行，关于怎么写corn这里就不赘述了 

schedule.scheduleJob('42 * * * *',()=>{
  console.log('success');
})
