This article is meant for anyone who wishes to quickly start developing an embedded Linux web application with access to the hardware GPIO, so that the user can control and/or monitor a system remotely. The application developed here, is based on the Colibri VF61 CoM (Computer on Module) by Toradex + the Iris Carrier Board, and a PCB with LEDs and switches. The main goals are to walk the reader through the process of developing Node code for accessing the GPIO via filesystem, building a simple yet user-friendly UI, and using the Express framework for hosting a minimal webserver that communicates with the client-side application by AJAX calls.
