During the great PHP Benelux Conference 2015 edition I published the final version of Principles of Package Design. Let me tell you a little bit about its history and some of the things I had to deal with.

A bit of history

My first book, A Year With Symfony, was released on September 4th, 2013. Just 6 days later, I started working on Principles of PHP Package Design. As it turned out, it was quite hard to keep the process going. There were several months in which I wrote nothing at all. Sometimes I picked up the work, but then I had completely lost my track and tried to get back on it by revising existing chapters over and over again. Meanwhile all kinds of other projects begged for attention as well, including the release of the backend project of the new nos.nl website, the preparations for the Hexagonal architecture training and the birth of our daughter Julia ;)

Yesterday I presented “Principles of PHP Package Design” at the monthly meetup of the AmsterdamPHP usergroup. This was quite an experimental presentation. I had prepared it on the same day actually, though I had been gathering the contents of it for several weeks.

Package design is a subject I’m very much interested in and you can be sure to hear more from me about it. Actually, I started writing a book about it! If you’re interested too, sign up on leanpub.com/principles-of-php-package-design.

Below you will find the slides for my presentation about Dependency Injection Smells (see also one of my previous posts from which this idea originated). If you have any questions, or feedback, please let me know by posting a comment below (or on joind.in).
