Making Discord bot do things automatically on a daily routine

Question

I am new to java script and discord programming and I want a bot at my discord server to do a channel purge at 5o'clock in the morning. However, I want to run it on a dedicated server and don't know how to properly set up the time trigger mechanic. Will

if (date.getHours()==5){
   //do stuff
}

work?

You can use client.setInterval() to have timed functions.

For example: client.setInterval(() => purgeChannel(), 300000); will run the function purgeChannel every 5 minutes (300000 is 5 minutes in milliseconds).

Does that mean that I cannot set a specific starting point in time? – Salatgurke Apr 22 '20 at 15:40
If you want to use a specific time then this might be your solution: https://stackoverflow.com/a/19089196/13176517 – Syntle Apr 22 '20 at 15:48

The easiest way I could see you doing this, was an Object with each action saved to a time. I choose to use <HOUR><MINUTE> to store each value. So a 4:12PM time would be: 1612. Then a setInterval to run every minute and check if it needs todo a new action.

function hello() {
  console.log('Hello');
}
let actions = {
  "0630": function() {
    console.log('Its 6:30');
  },
  "1200": hello, //NOON
  "1400": hello, //2:00 PM
  "0000": function() {
    console.log('New Day / Midnight');
  },
};
let codeStartTime = new Date();

function checkActions() {
  let date = new Date();
  let action = actions[`${date.getHours() >= 10 ? "" : "0"}${date.getHours()}${date.getMinutes() >= 9 ? "" : "0"}${date.getMinutes()}`];
  if (typeof action === "function") action(); //If an action exists for this time, run it.
}
setTimeout(function() {
  checkActions();
  setInterval(checkActions, 60000); //Run the function every minute. Can increase/decrease this number
}, ((60 - codeStartTime.getSeconds()) * 1000) - codeStartTime.getMilliseconds()); // Start the interval at the EXACT time it starts at a new minute


/** CODE for the Stack Overflow Snippet **/
console.log(`Starting first interval in ${((60 - codeStartTime.getSeconds()))} seconds.`);
console.log(`Adding in StackOverflow function, set to run at: ${codeStartTime.getHours() >= 10 ? "" : "0"}${codeStartTime.getHours()}${codeStartTime.getMinutes() >= 9 ? "" : "0"}${codeStartTime.getMinutes() + 1}`);
actions[`${codeStartTime.getHours() >= 10 ? "" : "0"}${codeStartTime.getHours()}${codeStartTime.getMinutes() >= 9 ? "" : "0"}${codeStartTime.getMinutes() + 1}`] = function() {
  console.log('Ran the StackOverflow Function');
};

If you choose to, you can wait for the any of my example times in the actions Object just to prove it works. But the StackOverflow code just adds a sample time to your current time +1 minute in the actions Object just to make it easier to see it in action.

setInterval is used here just to be simple, but not really recommended if this will run all day. Reason Why. To have a more exact time, I suggest replacing the setInterval to a setTimeout and just re-define the setTimeout everytime it's ran.
