An introduction to service APIs

Every company starts with a single website or web application, but as a company’s internet presence grows, many different applications and websites are deployed. With a traditional approach of treating each of these applications as a completely separate solution, a number of problems occur. But by introducing a service API the problems of the traditional approach can be overcome...

Manage project dependencies with Bower and Composer

As developers, most of us rely on third-party libraries as part of our web applications. PHP developers manage their dependencies with Composer, but how can you manage your client-side dependencies? Most projects start with one core JavaScript library (e.g. jQuery) and one or two plugins, but over time the application grows, and the list of JavaScript libraries grows as well. In this situation, Bower can help you, and in this article you will see how to integrate it into your own project.

Let RabbitMQ do the work in your Symfony2 application

Many of the high-performance websites we create nowadays must sometimes perform tasks that take a relatively large amount of time, such as sending an user an email after registration, creating a thumbnail from an avatar, or processing a large XML or CSV import file. Some of these tasks require a lot of memory, others just take time to complete. It would be great to avoid a delay for the user who just registered and needs us to send him an email or to have a nice, scalable architecture to parse big files efficiently.

Profiling with XHGUI

Profiling is a technique for observing the performance of an application, ideal for showing up bottlenecks or particularly intensive use of resources. Profiling gets inside your application and gives information about the performance of the various parts of code that are used during a request, so as well as being able to identify which requests may have problems, we can also identify where in each request any performance issues actually lie. We have a choice of tools for PHP but in this article we'll focus on an excellent tool called XHGui. XHGui is a tool built upon XHProf, the profiling tool released by Facebook, but adding better storage of metrics and a much nicer interface for retrieving information from it, to the extent that it feels like a new tool in it's own right!
