Can I delay loading Intercom on my site to reduce the JS load?

You can modify the Intercom load function by splitting it out like this, and it runs inside a setTimeout function

      // Intercom

      window.intercomSettings = {

        app_id: "<YOUR WIDGET ID>"

      };

     var w = window;

    var ic = w.Intercom;

    if (typeof ic === "function") {

        ic('reattach_activator');

        ic('update', w.intercomSettings);

    } else {

        var d = document;

        var i = function() {

            i.c(arguments);

        };

        i.q = [];

        i.c = function(args) {

            i.q.push(args);

        };

        w.Intercom = i;

        var l = function() {

            var s = d.createElement('script');

            s.type = 'text/javascript';

            s.async = true;

            s.src = 'https://widget.intercom.io/widget/lt;YOUR WIDGET ID>';

            var x = d.getElementsByTagName('script')[0];

            x.parentNode.insertBefore(s, x);

        };

        l();

    }

The difference is that the part that runs l() normally is onLoad and that gets stuffed up after the setTimeout.

You can also strip out the l() function entirely if you like (and just have the variables declared etc) and just run it, as it’ll be wrapped in a setTimeout function.

But I don't see any use of setTimeout in the code?

Thank you Roy! I'm trying to get this working with tagmanager. I can see it firing (on window load) but no sign of Intercom appearing. No console errors either. Any suggestions for me?

A complete working example would be awesome

Also, Intercom ought to distribute the code using setTimeout by default. Google is punishing us despite brilliant page load speed because the Intercom bubble takes more than four seconds to appear.
