    Just include the JS in your page. Something like this:

    HTML

    <html>
    <head>
        <!-- snip -->
        <script src="path/to/console/wrapper.js"></script>
    </head>
    <body><!-- snip --></body>
</html>

    JavaScript

    // drop this in the file referenced above
window.log=function(){log.history=log.history||[];log.history.push(arguments);if(this.console){console.log(Array.prototype.slice.call(arguments))}};

    This gives you a reverse-chronological history of everything that’s been logged, stored in log.history. Want to see the first thing logged?

    > log.history[0]

    Want to the the last thing logged?

    > log.history.slice(-1)
