I took it upon myself to give our customer portal at work a facelift (as it was in dire need of it). I started by adding bootstrap and re-designing the pages from the ground up. As this slight facelift went from a slight tweak to a full-blown project, I started integrating the HTMX library to add reactivity to this ancient site. I used PHP and MySQL (as this is what the project was based on originally) to create endpoints which would send back html snippets which hydrated the data on the page. This majorly boosted User Experience and now is an attractive selling point for our customers.
