我需要一个Nodejs调度程序，允许在不同的间隔任务 [英] I need a Nodejs scheduler that allows for tasks at different intervals

问题描述

我正在寻找一个节点作业计划，这将允许我以不同的时间间隔计划多个任务。例如

I am looking for a node job schedule that will allow me to schedule a number of tasks at different intervals. For instance,

• 每30秒呼叫功能A


• 每60秒呼叫功能B
• 
  
• 每7天调用函数C

我也希望能够启动和停止进程

I also want to be able to start and stop the process.

到目前为止，我已经看过了：

So far, I have looked at:

• a href =https://github.com/bunkat/later>稍后 - 语法使我感到困惑，显然您无法安排超过一个月的任务。

• later - the syntax confuses me, also apparently you cant schedule tasks beyond a month

议程 - 似乎最有前途，但我对数据库功能感到困惑。

agenda- seems the most promising, however I'm confused about the database functionality

timeplan - 简单，无法启动和停止

timeplan - to simple, can't start and stop

我发现后者混淆的语法

推荐答案

我会推荐 node-cron 。它允许使用Cron模式运行任务，例如

'* * * * * *' - runs every second
'*/5 * * * * *' - runs every 5 seconds
'10,20,30 * * * * *' - run at 10th, 20th and 30th second of every minute
'0 * * * * *' - runs every minute
'0 0 * * * *' - runs every hour (at 0 minutes and 0 seconds)

但更多复杂时间表

'00 30 11 * * 1-5' - Runs every weekday (Monday through Friday) at 11:30:00 AM. It does not run on Saturday or Sunday.

示例代码：每10分钟运行一次作业：

Sample code: running job every 10 minutes:

var cron = require('cron');
var cronJob = cron.job("0 */10 * * * *", function(){
    // perform operation e.g. GET request http.get() etc.
    console.info('cron job completed');
}); 
cronJob.start();

我在许多项目中使用过这个库，它的工作。我希望这将有所帮助。

I've been using that library in many projects and it does the job. I hope that will help.
