Serve data from txt file to dashboard template

[Chapo]

Hello!

I have managed to serve motion data to a data.txt file and inject a timestamp which now sits happily on my pi.  Seperately, I have managed to serve up the last event via a template on the dashboard.  However, my true objective is to serve up the last 50 or so events from the data.txt file into the template.  Can anybody point me in the right direction please?

Tail is one option quite easy if your new to node.js or JavaScript coding

Thanks for coming back to me Adrian most appreciated.

Below is the javascript for my motion output.  How would I incorporate tail here please, with the historic data coming from the text file?

<h3>Last Recorded Motion</h3>

{{msg.payload}}

<script>

    (function(scope) {

        console.log('Position 1');

        console.dir(scope);

        console.log(scope.msg);

        scope.$watch('msg.payload', function(data) {

            console.log('Position 2');

            console.dir(data);

        });

    })(scope);

</script>

Thanks in advance
