Using Symfony Finder and YAML components to transform Drupal 8 configurations to eZ
May 10, 2016 @ 10:58:31

On the Symfony Finland blog there's a tutorial posted showing how to translate Drupal 8 configurations into ones for eZ Platform using a bit of code inside a Symfony command.

Bolt CMS, Drupal 8 and eZ Platform all content management systems that use Symfony in one form or another. All of them use YAML to store configurations of content types and other system properties. This is great as it makes transferring between different formats quite straightforward.

This could be done by hand, but ideally configurations can be converted programatically. In this article we'll take a look at how to transfer content types from Drupal 8 to eZ Platform using a standard Symfony Command.

He starts with some background about the two configuration types (Drupal 8 and eZ Platform) before getting to the actual code to make the transformation. The code translates the Drupal 8 configurations over to the Kaliop Migrations format that can then be used in various environments. They include an example of the resulting configuration structure and, finally, the code to make the translation (allowing for multiple object types too).

Alejandro Celaya:
Improving ZendServiceManager workflow with annotations
Apr 11, 2016 @ 10:19:57

In a post to his site Alejandro Celaya shows you how to make life easier when using the ZendServiceManager with the help of annotations and a package he's developed to make it all work together.

Everyone who regularly visits my blog knows that I'm a complete fan of the ZendServiceManager component. It is always my choice to deal with dependency injection in any kind of project, more now that v3 has been released, which is faster and has a better public API.

The workflow while working with the ServiceManager is usually the same. You create a factory or abstract factory that creates a service and then you register that service into the ServiceManager itself. Of course you have to optimize your code, and you should try to reuse the same factories whenever possible, and try not to abuse of abstract factories and initializers.

He points out the main problem with using services like this in a larger application, namely that you can end up with a large amount of them, making them difficult to manage (and find problems with). He proposed solution uses this library to minimize the amount of code needed buy injecting dependencies into the service based on "inject" annotations. He includes an example of this functionality in action and includes a few things to keep in mind using the package (like the slower parsing of the annotations some limitations it currently has).

Loïc Faugeron:
The Ultimate Developer Guide to Symfony - Web Example
Mar 30, 2016 @ 10:50:17

In a previous post Loïc Faugeron showed you how to take all of the components he'd talked about so far and make a simple API endpoint. In this latest post he takes the same functionality and makes a web-facing example instead.

In this guide we've explored the main standalone libraries (also known as "Components") provided by Symfony to help us build applications: HTTP Kernel and HTTP Foundation, Event Dispatcher, Routing and YAML, Dependency Injection and Console. We've also seen how HttpKernel enabled reusable code with Bundles, and the different ways to organize our application tree directory.

Finally we've started to put all this knowledge in practice by creating a "fortune" project with an endpoint that allows us to submit new fortunes.

In this article, we're going to continue the "fortune" project by creating a page that lists all fortunes.

He goes through a similar process as before, but with a few changes to make it output a web page instead of API (JSON) results:

  • Create the Controller
  • Configure related routing
  • Create the logic to list all current fortunes
  • Putting the "wiring" in place to connect it to the database
  • Creating the view to output a simple page with the fortune list

It's that last step that's different, resulting in a simple (non-templated) page being output with HTML markup. He then refactors this to use Twig as the templating output layer, removing the output generation from the application logic.

Loïc Faugeron:
The Ultimate Developer Guide to Symfony - API Example
Mar 25, 2016 @ 10:31:09

Loïc Faugeron has posted another article in his "Ultimate Developer Guide to Symfony" series today. In this new article he shares an API example making use of the knowledge gained from the other articles to create a simple project.

In this guide we've explored the main standalone libraries (also known as "Components") provided by Symfony to help us build applications: HTTP Kernel and HTTP Foundation, Event Dispatcher, Routing and YAML, Dependency Injection and Console.

We've also seen how HttpKernel enabled reusable code with Bundles, and the different ways to organize our application tree directory. In this article, we're going to put all this knowledge in practice by creating a "fortune" project with an endpoint that allows us to submit new fortunes.

He starts by creating the project (via Composer's create-project command), sets up a basic routing configuration and installs PHPUnit for testing. He then shows the creation of the controller - test first - to handle the "fortune" endpoint requests. He then comes back in and adds in some logic around the submission including matching tests. This is then refactored further to use Doctrine to insert the contents into a database. Additional code is provided showing how to "wire it all together" and create the database structure. The entire post takes the TDD approach so tests for all submission functionality are included.

Symfony Blog:
New in Symfony 3.0
Mar 16, 2016 @ 09:39:21

On the Symfony blog there's a new post briefly looking at Symfony 3 and what's different about it as compared to previous releases (and what's not).

Symfony 3.0.0 was released on November 2015 as planned by the Symfony 3 roadmap. As we do with any new Symfony version, we should publish a blog series explaining its new features.

However, Symfony 3.0 is a very special version which contains no new features comparing it with Symfony 2.8. Their only difference is that 3.0 removed any feature marked as deprecated in 2.8. That's why we won't publish any "New in Symfony 3.0" post. Instead, let's do a quick recap of the new Symfony 2.8 features which are also available on Symfony 3.0.

Among the items on their list are things like:

  • New components like Guard Authentication and LDAP
  • A MicroKernel component
  • Improvements for VarDumper, Console and the Security components

Each of the changes on their list include links to get more information about the component and the post wraps up with a quick "how-to" on upgrading to Symfony 3 from other releases.

Loïc Faugeron:
The Ultimate Developer Guide to Symfony - Bundle
Mar 09, 2016 @ 10:53:40

Loïc Faugeron is back again with another of his "Ultimate Developer Guide" tutorials in his series. In his latest he looks at the Bundle component and the functionality it introduces as it relates to some of the components already discussed (like HttpKernel).

In this guide we've explored the main standalone libraries (also known as "Components") provided by Symfony to help us build applications: HTTP Kernel and HTTP Foundation, Event Dispatcher, Routing and YAML, Dependency Injection and Console. In this article, we're going to have a closer look at how HttpKernel enables reusable code.

He starts by comparing the HttpKernel and Kernel components, laying them out so that their use makes sense later. From there he then gets into the actual Bundle component. He introduces the component, provides a code example showing its interface and talks about situations where bundles could be useful. To help make it a bit more "real world" he then shows how to create a "NanoFrameworkBundle" complete with Extension, Compiler, configuration and bundle definition examples.

Abdul Malik Ikhsan:
Start Using Middleware Approach with new zend-mvc
Mar 02, 2016 @ 12:54:37

Abdul Malik Ikhsan has a post to his site showing how you can integrate the concept of middleware in to the Zend MVC Component of the Zend Framework. Middleware has come into its own with the acceptance of of the PSR-7 standard and several frameworks adopting its structure for request/response handling.

zend-mvc 2.7.0 is coming, beside of the forward compatibility with V3 components, there is new middleware listener that allow us to do Dispatching PSR-7 middleware. The middleware can be an invokable class with __invoke() method.

He shows how, starting with a new project, to create the middleware class (in this case HomeAction) and the __invoke function. He then adds in the "home" route to the module configuration and points it at this HomeAction class. He registers it in the service manager as an InvokableFactory and it magically works. From there he refactors to allow the middleware to work with the ViewModel and change things like templates and variable values.

Loïc Faugeron:
The Ultimate Developer Guide to Symfony - Console
Mar 02, 2016 @ 09:34:21

Loïc Faugeron is back again with another in his "Ultimate Developer Guide" series each focusing on an individual component of the Symfony framework. In this new article he focuses on a very widely used component - the Console component.

In this guide we explore the standalone libraries (also known as "Components") provided by Symfony to help us build applications.

We've already seen: HTTP Kernel and HTTP Foundation, Event Dispatcher, Routing and YAML [and] Dependency Injection. We're now about to check the last one: Console.

He starts with the definition of an Application class and gives an example of using it to make a simple command line script. He talks about some of the built-in features and how to create Command classes that hold the actual functionality in your command-line tool. He finishes up the post by talking about the input, output and styling functionality also included with the component and how they can be used.

Richard Melo:
Run legacy PHP applications from command line
Feb 15, 2016 @ 11:55:49

Richard Melo has a post to his site sharing some helpful advice about running legacy PHP applications from the command line making use of the Symfony Console component to handle some of the heavy CLI duties.

Imagine that you already have a trustfully application that you have been running for a while, but there is a couple of common patterns that make you consider that you need a command line interface (CLI) for your application. [...] So, how do we do this? especially without reinventing the well?

He starts off with an example of the problem, having a bit of a legacy application that needs to take in data (in this case JSON) and handle it would requiring a form submission. He makes use of the Console component to wrap this functionality inside a command and take a JSON file as input. He includes the example code needed to make this simple setup including the Command class itself and a small "bootstrap" command line script to do the actual command execution. The post ends with an example of the command you'd use to run the script and push in the JSON contents.

Geert Eltink:
Zend-Expressive Console CLI Commands
Feb 12, 2016 @ 11:21:15

In a new post to his site Geert Eltink shares how he added console command support to Zend Expressive, a PSR-7 framework from Zend that recently hit it's v1.0 mark.

zend-expressive does not come out of the box with a console for handling cli commands. However it's easy to add this and make full use of the container and its dependencies.

He uses the Symfony console component to handle most of the "heavy lifting" with the command line interaction, pulled in via Composer. He shows the process for getting the component installed and how to create the "bootstrap" file needed to build an instance of the Application class. He follows this with a simple "greeting" command including the configuration to add a few arguments and output the simple "Hello" message. He then creates the functionality to wire it in to the Zend Expressive application and gives an example of it in use.
