PSR-7 Request and Method Utilities

We all know the standard HTTP request methods and status codes, right? Or do we?

We definitely know whether or not they should be integers or strings, and/or how string values should be normalized, right?

And our IDEs can totally autocomplete them, right?

Oh, that's not the case?

Automating PHPUnit with Node

I've been trying to automate everything this year. When working on OSS, this is usually as simple as setting up Travis CI; in some cases, even that becomes a little more involved, but remains possible.

But that's continuous integration. What about continuous development?

Using Composer to Autoload ZF Modules

One aspect of Zend Framework 3, we paid particular focus on was leveraging the Composer ecosystem. We now provide a number of Composer plugins for handling things such as initial project installation, registering installed modules with the application, and more. It's the "more" I particularly want to talk about.

Push-to-Deploy with AWS CodeDeploy

AWS CodeDeploy is a tool for automating application deployments to EC2 instances and clusters. It can pull application archives from either S3 or GitHub, and then allows you to specify how to install, configure, and run the application via a configuration specification and optionally hook scripts. When setup correctly, it can provide a powerful way to automate your deployments.

I started looking into it because I wanted to try out my site on PHP 7, and do a few new things with nginx that I wasn't doing before. Additionally, I've accidently forgotten to deploy a few times in the past year after writing a blog post, and I wanted to see if I solve that situation; I'd really enjoyed the "push-to-deploy" paradigm of OpenShift and EngineYard in the past, and wanted to see if I could recreate it.

Enrico first pointed me to the service, and I was later inspired by a slide deck by Ric Harvey. The process wasn't easy, due to a number of things that are not documented or not fully documented in the AWS CodeDeploy documentation, but in the end, I was able to accomplish exactly that: push-to-deploy. This post details what I found, some recommendations on how to create your deployments, and ways to avoid some of the pitfalls I fell into.

Programmatic Expressive

Enrico just returned from phpDay, where he spoke about Expressive and the upcoming Zend Framework 3. One piece of feedback he brought back had to do with how people perceive they should be building Expressive applications: many think, based on our examples, that it's completely configuration driven!

As it turns out, this is far from the truth; we developed our API to mimic that of traditional microframeworks, and then built a configuration layer on top of that to allow making substitutions. However, it's not only possible, but quite fun, to mix and match the two ideas!

On Deprecating ServiceLocatorAware

A month or two ago, we pushed a new release of zend-mvc that provides a number of forwards-compatibility features to help users prepare their applications for the upcoming v3 release.

One of those was, evidently, quite controversial: in v3, zend-servicemanager no longer defines the ServiceLocatorAwareInterface, and this particular release of zend-mvc raises deprecation notices when you attempt to inject a service locator into application services, or pull a service locator within your controllers.

The arguments go something like this:

  • "Dependency injection is too hard to understand!"
  • "This feature simplifies development!"
  • "If this is so bad, why was it in there in the first place?"

These are usually followed by folks:

  • saying they'll switch frameworks (okay, I guess?);
  • asking for re-instatement of the feature (um, no);
  • asking for removal of the deprecation notices (why? so you can delay your pain until upgrading, when you'll ask for re-instatement of the feature?); or
  • asking for a justification of the change.

So, I've decided to do the last, justify the change, which addresses the reasons why we won't do the middle two, and addresses why the assumptions and assertions about ServiceLocatorAware's usefulness are mostly misguided.

Serve PSR-7 Middleware Via React

I've been intending to play with React for some time, but, for one reason or another, kept putting it off. This past week, I carved some time finally to experiment with it, and, specifically, to determine if serving PSR-7 middleware was possible.

Automating GitHub Pages Builds with MkDocs

One of the final tasks in prepping for the Expressive 1.0 release was setting up the documentation site. We'd decided to use GitHub Pages for this, and we wanted to automate builds so that as we push to the master branch, documentation is deployed.

The process turned out both simple and bewilderingly difficult. This post is intended to help others in the same situation.

Expressive 1.0 in the Wild!

A few hours ago, we pushed Expressive 1.0.

This is a huge milestone for the ZF3 initiative; I've even called it the cornerstone. It signals a huge shift in direction for the project, returning to its roots as a component library. Expressive itself, however, also signals the future of PHP applications we envision: composed of layered, single-purpose PSR-7 middleware.

Secure PHAR Automation

For a variety of reasons, I've been working on a utility that is best distributed via PHAR file. As has been noted by others ( link, due to lack of availability of original site), PHAR distribution, while useful, is not without security concerns, and I decided to investigate how to securely create, distribute, and update PHAR utilities as part of this exercise.

This is an account of my journey, as well as concrete steps you can take to secure your own PHAR downloads.
