Node.js Node-schedule How many minutes a scheduled task executes every minute _node.js

In Node.js, I use Node-schedule to perform timed tasks. Cron-style's time format is not intuitive for beginners, so it is generally used in this way: for example, the official example of 42 minutes per hour to perform the task

Copy Code code as follows:

var schedule = require (' Node-schedule ');

var rule = new schedule. Recurrencerule ();
Rule.minute = 42;

var j = schedule.schedulejob (rule, function () {
Console.log (' The answer to life, the universe, and everything! ');
});

So the question is, how do you perform a task every 15 minutes or 30 minutes?

The key point is that the rule.minute is supported by arrays, and knowing this is a good operation.

Perform every 15 minutes:

Copy Code code as follows:

Rule.minute = [0, 15, 45];

Similarly, each 30-minute execution:

Copy Code code as follows:

Rule.minute = [0, 30];
