Node.js设置定时任务之node-schedule模块的使用详解

npm install node-schedule
# 或
yarn add node-schedule

const schedule = require('node-schedule');

// 当前时间的秒值为 10 时执行任务，如2018-7-8 13:25:10
let job = schedule.scheduleJob('10     ', () => {
 console.log(new Date());
});

const schedule = require('node-schedule');

// 定义一个未来的时间
let date = new Date(2016, 6, 13, 15, 50, 0);

// 定义一个任务
let job = schedule.scheduleJob(date, () => {
 console.log(new Date());
});

const schedule = require('node-schedule');

// 定义规则
let rule = new schedule.RecurrenceRule();
rule.second = [0, 10, 20, 30, 40, 50]; // 每隔 10 秒执行一次

// 启动任务
let job = schedule.scheduleJob(rule, () => {
 console.log(new Date());
});

rule.second = [0,1,2,3......59];

rule.second = 0;

rule.minute = 30;
rule.second = 0;

rule.hour =0;
rule.minute =0;
rule.second =0;

rule.date = 1;
rule.hour = 10;
rule.minute = 0;
rule.second = 0;

rule.dayOfWeek = [1,3,5];
rule.hour = [0,12];
rule.minute = 0;
rule.second = 0;

job.cancel();
