在节点js中为日期范围设置cron作业

Question

I am working on a project where I need to send emails on the date which is in between two selected dates along with specific week days like only Monday and Thursday

The cron syntax is:

0 * * * * *

And the allowed values should be between below options

1. Seconds: 0-59
2. Minutes: 0-59
3. Hours: 0-23
4. Day of Month: 1-31
5. Months: 0-11
6. Day of Week: 0-6

I tried using node-schedule - npm . See my code below

var j = schedule.scheduleJob({ start: obj.start_date, end: obj.end_date, dayOfWeek: obj.dayOfWeek, hour: obj.hour, minute: obj.minute, second: 1 }, function(params){
         console.log(params);
    }.bind(null, obj));

I am able to run the jobs on dates but its not persistent. Whenever I make changes and starts the server it resets the scheduled jobs.

So how can I set a cron job which will run for specific dates(or date range) on selected days(Monday, tuesday etc)?

Answer 1

I got the work around on this. As I stored cron jobs in cache and whenever the server restarts, pushed them in to the cron again.
