Ready-to-use node-cron config
Drop this into your project. The expression is the one above.
import cron from 'node-cron';
cron.schedule('*/15 * * * *', () => {
console.log('running a task');
}, { timezone: 'UTC' });The node-cron fields, in order: second (0-59), minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), day-of-week (0-7, 0 and 7 = Sunday).
Things to watch out for in node-cron
- Steps restart at the top of each unit, as in standard cron, so */7 in minutes runs at 0, 7 ... 56 and then at 0 again.
- node-cron uses the server time zone unless you pass { timezone: "Asia/Kolkata" }. Its documentation advises timezone: "UTC" for jobs that must not skip or repeat when clocks change.
The common mistake with this schedule
In Quartz, 0/15 and */15 behave the same in the minutes field, but you still need a seconds value of 0 in front or the job fires every second of those minutes.
