The Image Gallery
The Image Gallery is the demo application for my upcoming book, Building Web Applications with Silex 2.
Much of the content is in flux at the moment. The goal of each chapter is to gradually grow the application into a fully functional image gallery with a database and an automated testing suite (although the focus is not on Test Driven Development).
The early chapters will grow the application organically, as often happens in the real world. Then, some test infrastructure will be brought in so that the resulting organic compost heap can be refactored into a well-structured and easily-maintained application.
The purpose of this intentional foray into the wildlands of organic code is twofold. One, it can be a helpful motivator for junior developers to see actual, executable progress as they work toward a goal. Two, it teaches a valuable lesson to those junior developers: even when a semi-working codebase looks like a flaming turd-nugget, it's usually possible to salvage it into a more rational structure.
It may come to pass that I change my mind on this concept. There's certainly a risk of misleading developers or inadvertently helping them develop bad habits.
I haven't decided.
