Moving a high traffic ZF1 Enterprise Application to SF2 - Lessons learned

Hautelook is a large ecommerce application that is currently running a Zend Framework 1 backend. The next iteration of its API (used by desktop, mobile, as well as iPhone and Android native applications) is done with Symfony 2. This API is following the principles for hypermedia APIs. To that end, Hal+Json is the media-type we chose, and we implemented most of it using the FSC HateoasBundle. Another critical piece of Hal+Json APIs is documentation. To this end we have used NelmioApiDocBundle to automatically generate documentation for the API endpoints. The other critical piece of any application is performance for which we use XHProf with XHGui. In my talk I want to touch on all those aspects, show some of the lessons learned, how we solved some of the problems, and what is still unsolved.

21. Issues This is fine when you have 5 end points and simple responses. Lots of boiler plate code Zend Framework 1 did not scale very well. We constantly had to overwrite parts of the framework.
22. Moving from Imperative to Declarative Programming [4,5] Imperative Declarative “In computer science, imperative programming is a programming paradigm that describes computation in terms of statements that change a program state.” “In computer science, declarative programming is a programming paradigm that expresses the logic of a computation without describing its control flow.”

24. Let’s use Symfony instead, shall we? [2]
25. Advantages: Symfony allows for way more declarative programming which allows us to write less code. Allows us to extend way easier. And it’s actually fun. Community is great.
