I would like to check the minute, until I get to :00, :05, :10, etc minutes, then set to 5 minutes (on the minute) and continue on during the application. Is there a better way to do this? Do I need a clearTimeout? Please help and thanks!
Goal: Check the minutes, once on 00, 05, 10, 15, 30, etc change to 5 minute interval and keep running.
// Set to 1 minute initially.
let interval = 60000;
function timeCheck() {
const date = getNow();
console.log("checking...", `${dayjs(date).hour()}:${dayjs(date).minute()}:${dayjs(date).second()}`);
// Check browser time in minutes for 00, 05, 10, 15, 20, etc.
if (dayjs(date).minute() % 5 === 0) {
// Set to 5 minute.
interval = 300000;
...
}
setTimeout(timeCheck, interval);
}
clearTimeout(timeCheck);
timeCheck();
console.log("Starting...");
const task = () => {
console.log("do something");
}
let minuteInterval;
const checkMinuteInterval = () => {
const date = new Date();
if (date.getMinutes() % 5 === 0) {
clearInterval(minuteInterval);
task();
setInterval(task, 1000 * 60 * 5);
} else {
console.log("Not on multiple of 5");
}
};
minuteInterval = setInterval(checkMinuteInterval, 1000 * 60);
checkMinuteInterval();A completely different approach, since this seems like an XY problem, is to just have an interval for every minute, check if it's a multiple of 5, if so do something, otherwise just break out of the function. (As suggested by @Heretic Monkey)
console.log("Starting...");
const task = () => {
if ((new Date()).getMinutes % 5 !== 0) {
console.log("Not a multiple of 5 minutes");
return; // would just be return; in production code
}
console.log("Do something")
// rest of function...
}
task();
setInterval(task, 1000 * 60);
