Strategic Domain-Driven Design in CakePHP
Strategic Domain-Driven Design in CakePHP
Slide Deck and Narrative for CakeFest 2022
About the Book
I joined the USA Clay Target League’s software team with the intent of becoming transformational within a year. It took three. In the PHP world, three years is far too long! Our software had “hit the wall” and needed a rewrite–or something. We weren’t sure what. We had a patchwork of spreadsheets and PHP scripts that grew along with us. We considered Domain-Driven Design, DDD.
DDD is scary because of the difficult learning curve. It’s not that we are scared to learn; it’s that we rarely have time to learn. Few PHP teams can afford to take on a multi-month or even multi-year experiment.
I learned that Strategic DDD is about communication and collaboration. That’s great, but once you have strategized, communicated, and collaborated, where do you put the code you write? This talk provides you that precise starting point. You’ll be able to immediately begin gaining your own hands- on Strategic DDD experience in your own project.
This talk is aimed at intermediate PHP, senior, and master software developers who’ve had some exposure to DDD but not necessarily any hands-on experience (that’s why we’re here).
This talk was presented at CakeFest, the CakePHP conference, September 29-30, 2022.
