Can someone share the most effective method to schedule an automated task every 24 hours in ExpressJS?
I have thoroughly researched possible solutions but haven't found any option other than using an infinite loop. Is there only one way to achieve this?
If you're looking to schedule tasks in Node.js, try using the node-cron npm package.
var cron = require('node-cron');
cron.schedule('0 0 * * *', () => {
console.log('running a task every day');
});
For more examples of cron formulas, check out:
To schedule tasks in JavaScript, the setTimeout() and setInterval() functions are used to run code at specific times in the future (more information available here). With setTimeout(), the code will execute once after a specified time interval. The setInterval() function will repeatedly execute the code at the specified interval.
If you have a server running continuously, simply using setInterval() is sufficient.
setInterval(myFunction, 1000 * 60 * 60 * 24);
This line of code will call the function myFunction every 24 hours.
In addition to these basic functions, there are more advanced scheduling tools such as those found in packages like node-schedule on NPM. These tools offer features like complex scheduling patterns (e.g., running every other day and twice on Mondays) and persistence across server restarts.
For instance, I use a setInterval() in my home automation server running on a Raspberry Pi to handle log management tasks once a day.
