Sometimes it is necessary to perform certain operations after the early morning of the evening. This may be helpful. I am studying this recently, and we welcome to discuss it together.

1. Installation
The code copy is as follows:
npm install node-schedule
2. Determine the time, for example: November 21, 2012, 5:30
The code copy is as follows:
var schedule = require('node-schedule');
var date = new Date(2012, 11, 21, 5, 30, 0);
var j = schedule.scheduleJob(date, function(){
console.log('The world is going to end today.');
});
Cancel the pre-designed plan
[code]
j.cancel();
3. Fixed minutes per hour, for example: 42 minutes per hour
The code copy is 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!');
});
4. A certain moment of certain days of the week, such as: every Thursday, Friday, Saturday, and 17 o'clock on the Sunday
The code copy is as follows:
var rule = new schedule.RecurrenceRule();
rule.dayOfWeek = [0, new schedule.Range(4, 6)];
rule.hour = 17;
rule.minute = 0;
var j = schedule.scheduleJob(rule, function(){
console.log('Today is recognized by Rebecca Black!');
});
5. Execute every second
The code copy is as follows:
var rule = new schedule.RecurrenceRule();
var times = [];
for(var i=1; i<60; i++){
times.push(i);
}
rule.second = times;
var c=0;
var j = schedule.scheduleJob(rule, function(){
c++;
console.log(c);
});
