I’m working on a Discord bot that needs to post messages at specific times, especially at midnight CET. Right now, I’m using a delay, but I want to find a better way to trigger a function exactly at 00:00.

My bot has an array of messages it should announce at midnight. I’m looking for advice on how to set this up correctly.

Here’s a snippet of my current code for storing data:

function handleCommand(message, command) {
  if (command === 'addArea') {
    const userInput = message.content.toLowerCase().split(' ').slice(2).join(' ');
    if (validAreas.includes(userInput)) {
      areasToAnnounce.push(userInput);
    } else {
      message.channel.send('Invalid area name. Please check and try again.');
    }
  }
}

Can anyone suggest a good approach for scheduling these midnight announcements? Thanks!

For your midnight scheduling needs, I’d recommend looking into the ‘discord.js-schedule’ library. It’s specifically designed for Discord bots and integrates seamlessly with discord.js. Here’s a basic setup:

const Schedule = require('discord.js-schedule');

const schedule = new Schedule(client);

schedule.scheduleJob('0 0 * * *', () => {
  areasToAnnounce.forEach(area => {
    // Your announcement logic here
  });
});

This approach is lightweight and doesn’t require additional dependencies. It also handles Discord rate limits automatically, which is crucial for avoiding issues with your bot.

Remember to initialize your client properly and handle any potential errors in your announcement logic. This method has served me well in several bot projects, ensuring reliable midnight posts without overcomplicating the codebase.

I’ve been in your shoes before, TomDream42. For scheduling tasks at specific times, I found the ‘node-schedule’ package to be incredibly reliable. It’s more flexible than cron in my experience.

Here’s how you could set it up:

const schedule = require('node-schedule');

// Schedule the job to run at midnight CET
const job = schedule.scheduleJob('0 0 * * *', function() {
  areasToAnnounce.forEach(area => {
    // Your announcement logic here
    console.log(`Announcing for ${area}`);
  });
});

This approach has worked wonders for me in production. It handles timezone differences smoothly, which was a lifesaver for my global user base. Just make sure your server time is correctly set to CET for accurate triggering.

Also, consider adding some error handling and logging to track successful runs and catch any issues. It’ll save you headaches down the line, trust me.

hey TomDream42, i’ve had similar issues. check out the node-cron package - it’s great for scheduling tasks. You can set it up like this:

cron.schedule('0 0 * * *', () => {
  // Your midnight announcement code here
});

This’ll run your function at midnight every day. hope this helps!
