Displaying errors in Expressive with Twig
Oct 19, 2017 @ 12:47:36

Rob Allen has a quick post for the Twig and Zend Expressive users out there showing how to display errors if you're not using the Whoops error handler.

If you're not using the Whoops error handler with Expressive and are using the Twig renderer, then you are given no information about the problem that occurred, even in debug mode.

He includes the Twig template to output the error message and, if the application is in "debug" mode, show an optional block of extra information. This provides details about the exception thrown and some of the previous errors. The previous errors are looped about output to provide more context around the failure.

SitePoint PHP Blog:
Rapid Development of Zend Expressive Modules
Sep 07, 2017 @ 11:49:43

The SitePoint PHP blog has a new post from Kirk Madera sharing some of the things he's learned about creating modules in Zend Expressive. His goal is to make it as easy as possible and enable "rapid development" in your application. This is the second part of a series on rapid development with Zend Expressive from Kirk (part one is here).

I have learned a few tricks when writing Zend Expressive modules that I want to share with you.

Please follow the previous post first to set up a proper working environment. I explained how to install and configure Zend Expressive with Doctrine, Gulp, and an abstract reflection factory – it’ll take a total of 10 minutes.

In this tutorial, we’ll build a simple read-only blog module (a page listing blog posts from a database) in minutes, demonstrating the kind of rapid development one is capable of with Zend Expressive.

He then shows how to use the command line tooling to create the module and how it is registered with Composer. He then shows the creation of the "blog" entity and database tables followed by the routing changes. Next he fleshes out the actions that will respond to the requests on each route and the templates that will be served as a part of the response.

SitePoint PHP Blog:
Rapid Enterprise App Development with Zend Expressive
Aug 29, 2017 @ 15:41:34

The SitePoint PHP blog has posted a new tutorial from author Kirk Madera showing you how to use Zend Expressive to aid in more rapid development in your applications.

If you’ve ever done a Zend Framework quick start, you’ve probably never worked in Zend Framework. The quick start has historically been anything but quick, and it’s easy to lose interest and move on to the next thing.

Zend Expressive greatly improves upon this experience with the wizard driven composer create-project command. However, it can still be daunting to set up because there are so many choices to make up front. This tutorial guides you through my recommended setup for rapid development which will yield an enterprise level, robust application.

He then walks you through the creation of a Zend Expressive project from scratch and how to ensure it's up and running as expected. He then walks you through the structure of the application, software it includes (like Doctrine and Gulp) and examples of them in use. The post ends with a look at creating console commands using the Symfony Console component.

Zend Framework Blog:
REST Representations for Expressive
Aug 09, 2017 @ 10:12:18

On the Zend Framework blog there's a new post from project lead Matthew Weier O'Phinney covering REST representations in Expressive and the release of two new components to help with their implementation.

We've been working towards our various Apigility on Expressive goals, and have recently published two new components: zend-problem-details and zend-expressive-hal.

These components provide response representations for APIs built with PSR-7 middleware. Specifically, they provide: Problem Details for HTTP APIs (RFC 7807) and Hypertext Application Language (HAL).

These two formats provide both JSON and XML representation options (the latter through a secondary proposal).

The post then goes on to talk about the idea of "representations" and how it relates back to the structure of the data returned and how the user knows what operations they can take on it. He also talks about the differences between normal responses and errors and gives example output helping to illustrate his points. The remainder of the post gets into the details of the two new components, their use and how to implement them in Expressive.

Master Zend Framework:
How to Create a Zend Expressive Module
Jul 26, 2017 @ 11:14:52

On the Master Zend Framework site Matthew Setter has written up a tutorial showing you how to create a Zend Expressive module to help organize your application and keep related files all in one place.

I've been reflecting recently on the things that I commonly have to do when I begin building Zend Expressive applications. Of the list that I created, I found that one of the most common — and uninteresting — of them is setting up the rendering of static page content. [...] To solve this, I've usually manually created modules to handle the rendering of static page content. These module's usually had little more than a PageAction class that returned an HtmlResponse object, whose body was a rendered template file.

[...] If you're in a similar position to where I was and want to collate the logic into a reusable module, then follow along with me in this tutorial I'm going to step you through how to create a module which you can reuse across any Zend Expressive project.

He starts by briefly describing a "module" in the context of a Zend Expressive application and how they relate (or don't) to the modules in Zend Framework v2. He then starts in on the module creation, showing how to set up the environment, change the Composer configuration to autoload correctly and describes what the end result should look like. From there the tutorial starts on the code required for the classes covering the basics of the class, exception handling, configuration and the creation of a factory to make a module instance.

Master Zend Framework:
How to Migrate from Zend Expressive Version 1 to 2 with Command-Line Tooling
Jun 27, 2017 @ 10:43:30

On the Master Zend Framework site Matthew Setter has written up a new tutorial showing you how to migrate from Zend Expressive v1 to v2 with the help of some command line tooling support provided as a part of recent updates to the project.

In part one of this series, we started learning about the tooling support available for Zend Expressive, provided by Zend Expressive Tooling There, we learned how we can use the package to create, register, and deregister middleware, and scaffold new modules. But that's only half of what the package can do.

Here, in part two, let's learn about the other half, which removes some of the heavy lifting required when migrating Zend Expressive applications from version one to two.

He first defines some of the main differences between the two versions, a checklist of things the tooling will help you more automagically update. He talks more specifically about migration support, moving to "programatic pipelines" in Expressive v2 and scanning for deprecated error middleware. There's also information about locating the legacy request and response handling and how they're refactored to the newer format.

Master Zend Framework:
Create Modules and Middleware with Command-Line Tooling Support
Jun 12, 2017 @ 10:44:05

The Master Zend Framework site has posted a new tutorial covering an aspect of the Zend Expressive project that doesn't seem to get enough coverage: the tooling included with the skeleton application.

For the longest time, Zend Framework hasn't had the strongest command-line tooling and scaffolding support. In stark contrast, other frameworks — especially Laravel, and its excellent Artisan command — have had far stronger tooling support and as a result have been far easier to build projects with. However, that's all changed!

Since the release of Zend Expressive Skeleton 2.0.2, Zend Expressive's command-line tooling support has been rapidly developing. It's provided through a package called, aptly, Zend Expressive Tooling.

The post briefly describes what features the tooling brings and then gets right into the installation process (via Composer). The tutorial then walks you through the commands it provides to create middleware, modules and handle migration to latest versions of the framework. The module and middleware topics are then covered more in-depth, showing code and commands required.

Alejandro Celaya:
How to customize "not found" and "method not allowed" response prototypes in Zend
May 31, 2017 @ 10:10:23

Alejandro Celaya has posted a new tutorial on his site showing how you can customized the "not found" and "not allowed" responses in a Zend Expressive v2 application based on the needs of your application.

Sometimes the nature of an application requires you to change the default framework's way to structure error responses (like 404 and 405).

On this article I'm going to explain how to customize those responses when working with Zend Expressive 2. [...] In Expressive 1, error handling was different. [...] In expressive 2, the error handler is gone, replaced by a middleware which catches exceptions and lets you generate error responses.

He notes that this new middleware approach (moving away from the error handler) doesn't deal with 404 and 405 errors anymore, they've been split out into other functionality. As these other middleware options allow for a custom PSR-7 response object to be injected, he sets up two "delegates" that will more correctly handle the response. He includes the examples code for these and shows how to hook them into the current Expressive execution flow.

Zend Framework Blog:
Leverage Zend Component Plugin Managers in Expressive
May 19, 2017 @ 09:58:15

The Zend Framework blog has a new post from project lead Matthew Weier O'Phinney showing how you can use plugin managers in Expressive and how it can be used to integrate other components.

With the release of Expressive 2, one of the key stories was the ability to require ZF components within Expressive, and have their dependencies auto-wired into your application courtesy of the component installer.

However, we recently had a user in our Slack channel (need an invite?) indicating they were having issues with usage of custom validators, filters, and input filters. After a <a href=https://discourse.zendframework.com/t/validatormanager-not-calling-custom-validator-factory/109">more thorough writeup on our forums, I realized we'd missed something important when making these integrations, and set out to solve it.

The article then starts with the problem that they're trying to solve, mostly around configuration handling. The solution involved some work done on various packages (like zend-log, zend-filter and zend-form) to make the configuration loading a bit more automated (and with fallback handling).
