I reverted to my language of choice – Perl to write my first web app and back end service.
I used Mojolicous Lite to generate the page and handle JSON get requests. On the backend I used sqlite and Perl to process and monitor the dnsmasq log file. The Perl hypnotoad web server sits behind a Nginx web proxy for deployment to the internet.
The end result is a simple web app that lets users of my Adblocker to see statistics for the service.
