crontab-node

yarn add crontab-node

crontab-node目的是配合linux的crontab使用, 需要每分钟执行一次，时间触发后才会执行函数方法

Example

c.js

const crontab = require('crontab-node');
const eventEmitter = require('crontab-node/eventEmitter');

eventEmitter.on('crontab-node exit', () => {
    process.exit(0);
});
const promise = new Promise((resolve, reject) => {
    setTimeout(() => {
      resolve();
    }, 1);
});

console.log(new Date());

crontab('*/2 * * * *', () => {
    return promise.then(() => {
        console.log('I am callback, just excute once');
    });
});

crontab -l

* * * * * node path/c.js
