For a coding challenge I programmed once an almost framework less online shop in a short time frame by using full stack technologies. As relational database I used MySQL. The back-end is programmed with PHP and the dependencies are managed with composer. On the front-end side HTML, CSS, JQuery, Javascript and Bootstrap are used. The code quality was improved by the use of PHPUnit. For easier shipping the applications runs in an Docker container. The full requirements for the coding challenge and the whole code base can be found in this repository:
