JS: Chat Timeout Functionality after X messages in a timeframe

Question

So I have to make a chat spam functionality. When the user send a message I want to check if it's the 15'th message the user sent in a 30 second timeframe. If yes I want to give the user a "Timeout" for 1 minute so he can't write anymore messages.

I'v struggled with this for a while now and can't find a good best practice answer. Thanks in advance.

Answer 1

I worked it out. Here is my solution:

var chatIsTimedOut = false;
var canWrite = true;
var msgsIn30s = 0;
var chatMsgStarted = false;

function addMsg() {
    if (msgsIn30s > 4 && canWrite) {
        console.log("timeout begin");
        canWrite = false;
        chatIsTimedOut = true;
        setTimeout(() => {
            canWrite = true;
            chatIsTimedOut = false;
            msgsIn30s = 0;
            console.log("tmieout away");
        }, 60000);
    } else if (canWrite) {
        msgsIn30s++;
        if (!chatMsgStarted) {
            chatMsgStarted = true;
            setTimeout(() => {
                chatMsgStarted = false;
                msgsIn30s = 0;
            }, 30000);
        }
    }

    console.log("Msgs: ", msgsIn30s);
    console.log("Can Write: ", canWrite);
}
