Javascript: Anti-spam Automoderator (Discord.js)

I am coding a multipurpose Discord bot to replace some of the more minor ones, and I am looking for a piece of code for a feature that recognizes repeated messages or messages sent in a very short time period (let's say 5000ms).

Here is what could be used to implement this idea.

client.on(message, (message) => {

//let's use something like a spam variable for 10 or more messages sent within 5000ms

if(message.content === spam) {

    message.reply(Warning: Spamming in this channel is forbidden.);

    console.log(message.author.username +  ( + message.author.id + ) has sent 10 messages or more in 5 seconds in  + message.channel.name + .);

  }

});

For reference, I also made a feature that deletes messages, using a ~delete [n] command. It looks like this:

//this will only delete one message in the channel, the most recent one.

    message.delete(1000);

//1000 represents the timeout duration. it will only delete one message, regardless of the value.



//we can delete multiple messages with this, but note it has to come before the reply message.

    message.channel.bulkDelete(11);

I was thinking of somehow combining the delete command with recognizing spam messages. If you have any ideas, that would be perfect.

Try This:

const usersMap = new Map();

const LIMIT = 7;

const DIFF = 5000;



client.on('message', async(message) => {

    if(message.author.bot) return;

    

    if(usersMap.has(message.author.id)) {

        const userData = usersMap.get(message.author.id);

        const { lastMessage, timer } = userData;

        const difference = message.createdTimestamp - lastMessage.createdTimestamp;

        let msgCount = userData.msgCount;

        console.log(difference);



        if(difference > DIFF) {

            clearTimeout(timer);

            console.log('Cleared Timeout');

            userData.msgCount = 1;

            userData.lastMessage = message;

            userData.timer = setTimeout(() => {

                usersMap.delete(message.author.id);

                console.log('Removed from map.')

            }, TIME);

            usersMap.set(message.author.id, userData)

        }

        else {

            ++msgCount;

            if(parseInt(msgCount) === LIMIT) {



               message.reply("Warning: Spamming in this channel is forbidden.");

              message.channel.bulkDelete(LIMIT);

               

            } else {

                userData.msgCount = msgCount;

                usersMap.set(message.author.id, userData);

            }

        }

    }

    else {

        let fn = setTimeout(() => {

            usersMap.delete(message.author.id);

            console.log('Removed from map.')

        }, TIME);

        usersMap.set(message.author.id, {

            msgCount: 1,

            lastMessage : message,

            timer : fn

        });

    }

})
