Programming and Design:

Frontend: Responsive design for all kind of devices using:

CSS: tailwindcss (https://tailwindcss.com); currently 3.4.17,

slowly replacing Bootstrap (https://getbootstrap.com; currently 4.6)

JS: AlpineJS (https://alpinejs.dev/); currently 3.15.1

JS: Vue.js (https://vuejs.org; currently 3.5.13)

Icons: SVG icons from remixicon.com (open source)

•The application is being realized with the symfony-framework (https://symfony.com/;

•currently 7.4.6) using PHP (currently 8.4.13) and for templating Twig (https://twig.symfony.com)

•The database is MariaDB (currently 10.6.20)

•Audit trail with Symfony on-board tools tailor-made to our own solution

•Safe the audit trail: to prevent that the massive audit trail slows down our application we have externalized the audit function into a separate MariaDB database. This database also goes onto the monthly backup sitting on our NAS.

•Hosting is with Cyon Basle

•We started with the main language deployed being “German”. We are now using English, provisioning German and “French”. Expressions to be translated are grouped by entity / activity in a database table and is translated in the application itself.

•Merging PDF's of different versions does not work with PHP, unless you buy/license a library with this feature or use a paid API. So, to merge PDF's we build our own API service in Rust. The service runs under hech.e9li.io on a Infomaniak server in Geneva.
