DirectLineJS receiving copies of Bot replies

I'm using DirectLineJS to comminucate from a custom webchat through a website. I'm using the format posted from Microsoft's github https://github.com/Microsoft/BotFramework-DirectLineJS

how I have it implemented is 

var directLine;
    directLine= new DirectLine.DirectLine({
        secret: "My_DirectLine_Secret",
    });

    function sendReceiveActivity(msg) {
        document.getElementById("inputtext").value = "";
        conversation.innerHTML = conversation.innerHTML + "ME - " + msg + "<br/><br/>";

        directLine.postActivity({
            from: { id: 'myUserId', name: 'myUserName' }, // required (from.name is optional)
            type: 'message',
            text: msg
        }).subscribe(
            id => console.log("Posted activity, assigned ID ", id),
            error => console.log("Error posting activity", error)
            );

        directLine.activity$
            .filter(activity => activity.type === 'message' && activity.from.id === 'mybot')
            .subscribe(
            message => console.log(message)"
            );
    }

whenever I start reading the messages the number of copies increase by one through each message back and forth so the my website will go through this cycle:

Me - send message to bot

BotReply - msg 1

Me - send some message to bot

BotReply - msg 2

BotReply - msg 2

Me - some message

BotReply - msg 3

BotReply - msg 3

BotReply - msg 3

and so on

the response ID I receive from the bot doesn't increase either for repeated messages so say msg 3 had ID = 00005, each of the BotReply - msg 3 has ID = 00005, but msg 4 would be ID = 00007

In my actual bot I send my messages by using await context.PostAsync("Some mesage");and nothing else

what can I do to reduce the message replies to receive just one?

The documentation states "Direct Line will helpfully send your client a copy of every sent activity, so a common pattern is to filter incoming messages on from:" even though I am filtering my messages to be from "mybot"

It is difficult to determine exactly what is going on without seeing the rest of the code. However, it appears as if you are subscribing to receive messages every time you send a message. Please try changing your code so that you only subscribe once:

var directLine = new DirectLine.DirectLine({
        secret: "My_DirectLine_Secret",
    });

directLine.activity$
          .filter(activity => activity.type === 'message' && activity.from.id === 'mybot')
          .subscribe(
            message => console.log(message)
            );

    function sendReceiveActivity(msg) {
        document.getElementById("inputtext").value = "";
        conversation.innerHTML = conversation.innerHTML + "ME - " + msg + "<br/><br/>";

        directLine.postActivity({
            from: { id: 'myUserId', name: 'myUserName' }, // required (from.name is optional)
            type: 'message',
            text: msg
        }).subscribe(
            id => console.log("Posted activity, assigned ID ", id),
            error => console.log("Error posting activity", error)
            );
    }
