Example usage

Set and check cooldown when user uses a command

client.on("message", async (message) => {
  // example Command Handler
  let cmd = client.getCommand(message.content);
  if (!cmd) return;

  // Cooldown System
  let isEnded = await djs_cooldown.checkCooldown({
    identity: message.author.id,
    name: `text/${cmd.name}`,
  });
  if (!isEnded) return message.channel.send(`You are on cooldown!`);

  // cooldown not found or ended
  cmd.run(...);

  // set new cooldown
  await djs_cooldown.set({
    identity: message.author.id,
    name: `text/${cmd.name}`,
    cooldown: 15 * 1000, // 15 seconds in ms
    usedAt: Date.now()
  }, function(error, message) {
    if(error) console.error(error);
  });
});

Features

Database Utilities

await djs_cooldown.setDB("mongodb+srv://..."); // new connetion URL

// You need to re-connect to MongoDB to change URL
await djs_cooldown.disconnect();
await djs_cooldown.connect();

// or simple way
await djs_cooldown.reconnect();

// shorter
await djs_cooldown.setDB("mongodb+srv://...", true); // "true" here means turn on automatically reconnect when reset connection URL

// Refresh Database connection state (avoid package required connect another time to use)
await djs_cooldown.refreshDB(); // Will log again if already connected

Cooldown Ultilities

// Set new cooldown for user
await djs_cooldown.set({
  identity: "1234812",
  name: "somethingherer??",
  cooldown: 15 * 1000,
  usedAt: Date.now(),
});

// Remove a created cooldown if you think something went wrong
await djs_cooldown.remove({
  identity: "1234812",
  name: "somethingherer??",
});

Check is cooldown ended

await djs_cooldown.checkCooldown({
  identity: "1234812",
  name: "somethingherer??",
});

// > true
// Is the cooldown ended? (true/false)

Count "Time Left"

await djs_cooldown.timeLeft({
  identity: "11111111111",
  name: "somethinghereig?",
});

// > 123412
// Time left in milliseconds

• Output: Time in MS
• If no data was found or timeLeft < 0, output will be 0
