The how and why of composable Magento

Ask any developer and they will likely say reuse is very important to them. They have been taught or learned about DRYand now apply it to their code. However, what about features of the application? Many features are similar between applications so why would we repeat the writing of them?

Composable applications can be reused in a myriad of different ways you just combine the features the way you need them this time around.

This presentation applies this thinking to Magento. Showing how this can be done with the Magento 1.x branch and the module ecosystem. It then goes on to show how this thinking is at the core of Magento 2.0

But why should you develop with composable, modular code?

Because it answers the intention of reuse and DRY in a much more tangible way. This presentation will show you not just how but why, with some real World experience to go beyond the theory.
