Tasty task scheduler with a mungable internal clock filling.
$ npm install --save cronut
import cronut from 'cronut';
const cron = cronut();
cron('0 0 0 * * *', () => {
console.log('another hour');
});
cron('0 0 * * * *', () => {
console.log('another minute');
});
cron('* * * * * *', () => {
console.log('another second');
});
cron('0 30 0,12 * * 1-5', () => {
console.log('12:30 AM and PM on weekdays');
});
const removeTask = cron('0 * * * * *', () => {
// only run 10 or so times
console.log('another second');
});
// Unschedule after 10 seconds
setTimeout(removeTask, 10000);
Creates a new task scheduler.
import cronut from 'cronut';
const cron = cronut();
pattern
String
task
Function

Object
resolution
Number

.
Patterns are any valid pattern supported by cron
. The task is the function to be executed at the appointed times. Returns a function to stop the task.
cron('* * * * * *', () => {
console.log('another second');
});
// same as
cron.addTask('* * * * * *', () => {
console.log('another second');
});
// removable
const removeTask = cron.addTask('* * * * * *', () => {
console.log('another second');
});
removeTask();
fn
Function
Sets the moment.now
function and resets internal cron timers.
cron.now(() => {
// It's tomorrow! Heh heh.
return Number(new Date()) + (24 * 60 * 60 * 1000);
});
There are a bunch of task schedulers already available, but none of them allowed me to mess with the internal clock for timeline manipulation or testing purposes.
