Writing Custom Laravel Artisan Commands
Aug 09, 2017 @ 12:20:29

On the Laravel News site they've posted a tutorial showing you how to create custom Artisan commands making them available right along with the built-in framework commands.

I’ve written console commands in many different languages, including Node.js, Golang, PHP, and straight up bash. In my experience, the Symfony console component is one of the best-built console libraries in existence—in any language.

Laravel’s artisan command line interface (CLI) extends Symfony’s Console component, with some added conveniences and shortcuts. Follow along if you want to learn how to create some kick-butt custom commands for your Laravel applications.

The tutorial starts off with an overview of the current command structure and how a basic Symfony Console command is structured (code). They then get into the creation of their custom command - a "health check" command - by creating a new Laravel project and using the "make:command" command to build out the skeleton code for you. They add the command into the current config and show output of how it should now show in the "help" listing. From there the tutorial shows how to implement the HTTP checking with Goutte and how ot run it on a schedule, writing the result of the check to a log.

SitePoint PHP Blog:
Introducing the Neo4j Symfony Bundle
Aug 07, 2017 @ 13:25:34

On the SitePoint PHP blog they've posted a tutorial from author Tobias Nyholm introducing the Neo4j bundle for Symfony-based application. This bundle provides functionality to work with Neo4j graph databases natively in the application.

There is no such thing as disconnected information, no matter where you look – people, events, places, things, documents, applications and the information about them is all heavily connected. As the volume of data grows, so does the number and dynamicity of its connections. And if you’ve tried in the past to store and query that highly connected, semi-structured data in any database, you probably experienced a lot of challenges.

The tutorial talks some about graph databases, how they work and what kind of data fits into them best. It also briefly covers the Cypher Query Language followed by an introduction to the bundle and what it has to offer. Code examples of putting the bundle to use for queries are provided including the models to handle the results, relationships and an example application you can use to start with a working example.

Matthias Noback:
Layers, ports & adapters
Aug 04, 2017 @ 11:43:11

Matthias Noback has a series of posts on his site sharing some of his thoughts around layers, ports and adapters in application architecture:

Looking back at my old blog posts, I think it's good to write down a more balanced view on application architecture than the one that speaks from some of the older posts from 2013 and 2014. Before I do, I allow myself a quick self-centered trip down memory lane.

He's posted all three parts of the series, each providing either some background on him and his previous work or principles and architecture suggestions:

Each part includes code and/or structure suggestions to help clarify points made along the way.

Symfony Blog:
The CFP process for SymfonyCon and SymfonyLive events
Aug 01, 2017 @ 09:17:41

On the Symfony blog they've shared a post giving you an "inside look" at their Call for Papers process for the SymfonyCon and SymfonyLife events. Each conference is different and has a different process for attracting speakers and selecting them once the Call for Papers has completed.

All the Symfony conferences we organize are aimed at gathering the Symfony community together to enable every community member to meet each other, share best practices and learn tips and about new features. This all happens in a convivial atmosphere that feels like a big family reunion. The highlight, of course, is listening to high quality talks. The speaker line up is very important to us and we take great care to make sure the talks we select will be appreciated and useful for the majority of conference attendees.

[...] The CFP criteria are available online and are the same for all the conferences: we're looking for the best Symfony-focused topics that are relevant to the community. We don't select speakers based on any racial, gender or physical criteria: all the talk proposals received are studied no matter who the speaker is.

They talk about what they provide to speakers, how they review the talks once the CFP is complete and some about the committee that does the selection. With the speakers they want selected they then send out the acceptance notifications and confirm schedules. The post finishes up talking about their emphasis on trying to improve the ration of female to male speakers and their code of contact.

Tomáš Votruba:
The Bulletproof Event Naming For Symfony Event Dispatcher
Jul 21, 2017 @ 12:39:28

In a recent post to his site Tomáš Votruba shares what he sees as a "bulletproof" event naming scheme for use with the Symfony event dispatcher component.

I wrote intro to SymfonyEventDispatcher and how to use it with simple event.

But when it comes to dispatching events, you can choose from 4 different ways. Which one to choose and why? Today I will show you pros and cons of them to make it easier for you.

He then breaks up the remainder of the post into the four suggestions, each with code examples and brief descriptions:

    1. Start with Stringly
    1. Group File with Events Names as Constants
    1. ...Constant Names in Particular Event Classes
    1. Class-based Event Naming

For each he also includes some "pros" and "cons" to help you select which one might work best for your usage. He ends by taking things "a step further" and sharing integrating a suggestion to remove an argument and simplify the code.

Why you should learn Symfony in 2017
Jul 18, 2017 @ 12:39:09

On the Hackermoon site there's a new post from developer advocate Mickaël Andrieu sharing a few reasons why he thinks you should learn Symfony in 2017 if you haven't already.

In 2011, when I started my studies in computer sciences I learned the PHP using symfony 1.3, and I realized my very first student project on the beta of Symfony 2. At the time, we were moving from a fully integrated full stack framework with a back office provided to a framework that followed what was found in the Java community: besides, many components of Symfony2 were strongly inspired by JEE.

PHP 5.3 had just come out and with it the ability to start designing object-oriented correctly. [...] Large Open Source projects have started to migrate on Symfony components: if it was not first, SensioLabs has talked a lot about Drupal8 because it is one of the biggest CMS on the market. EzPublish, PHPBB, PrestaShop and many others followed, some with a full stack framework approach and others by incorporating only a few software bricks.

He then talks about the "vibrant and mature ecosystem", listing some of the packages that use Symfony components. He also looks forward to the next major iteration of the framework: Symfony Flex. He ends with his reasoning why you should learn Symfony if you haven't worked with it (or at least how it handles common things like requests and services).

Gonzalo Ayuso:
Silex is dead (… or not)
Jul 10, 2017 @ 11:24:58

In a new post to his site Gonzalo Ayuso talks about the Silex project (a Symfony-based microframework) and how it just might be dead.

The last week was deSymfony conference in Castellón (Spain). IMHO deSymfony is the best conference I’ve ever attended. [...] This year I cannot join to the conference. It was a pity. A lot of good friends there. So I only can follow the buzz in Twitter, read the published slides (thanks Raul) and wait for the talk videos in youtube.

In my Twitter timeline especially two tweets get my attention. One tweet was from Julieta Cuadrado and another one from Asier Marqués. [...] Tweets are in Spanish but the translation is clear: Javier Eguiluz (Symfony Core Team member and co-organizer of the conference) said in his talk: “Silex is dead”.

He goes on to talk about how, despite the overly dramatic title, the Silex project isn't really "dead" but does have an uncertain future. He talks some about the next version of Symfony - Symfony 4 - and how, because if the changes since v3, it could essentially replace most of what Silex offers. Unfortunately, this also leads to another problem - Symfony 4 isn't ready and if Silex will be deprecated which should he choose for new projects? After some investigation, he decided that Lumen, a Laravel-based microframework, was just right for his needs.

Symfony Finland:
Drop-dead simple SASS builds in Symfony Flex with Webpack Encore
Jul 10, 2017 @ 10:17:42

The Symfony Finland site has an article posted introducing you to Symfony Encore, a tool that makes it simpler to manage frontend libraries and dependencies via Webpack.

Symfony Encore is a wrapper for the JavaScript module bundler Webpack. Webpack is used to manage Front End assets like JavaScript, CSS and image for browser consumption, often with conversion step from a source format like SASS. Encore provides an opinionated way to add Webpack to your Symfony projects.

[...] Earlier this year I experimented with sharing a state object with Symfony and different front end tools. Recently I ported the Symfony 3 application to Symfony Flex. Now I will continue the evolution of the app by adopting Symfony Encore to the project.

The article briefly introduces Encore and what functionality it provides before getting to the installation (via yarn) and configuration that it installs by default. The post then goes through the setup of SASS, using assets in your pages and running builds.

Fabien Potencier:
Symfony 4: Directory Structure Updates
Jul 05, 2017 @ 10:06:21

Fabien Potencier has a quick post to his site that may be of interests to the Symfony developers out there related to directory updates coming in Symfony 4:

After a long discussion in the community, the directory structure has been slightly changed.

etc/ was renamed to config/, and web/ to public/. My blog posts about Symfony 4 have just been updated to reflect these changes.

He also includes instructions about how, if you're already running a Symfony Flex application, you can make these changes manually including updating the Flex version.

Symfony Finland:
Porting a Symfony 3 application to Flex
Jun 26, 2017 @ 11:42:12

On the Symfony Finland site they've posted a retrospective about moving an application from Symfony 3 to Flex including the work that was done in the switch and the performance of the result.

Earlier this year I did some experimenting with a Hybrid state object between Symfony Twig templates and front end JavaScript frameworks. Since that time I did that experiment, the Symfony Flex project has progressed. I thought I would try how to port the state prototype to Symfony Flex.

[...] In my case the application was rather simple and all built in the AppBundle, which is best-practise in Symfony3 for many applications. I mostly had to move files and configurations around and change namespaces.

He starts by spending some time talking about the difference between a Symfony 3 environment and the environment Flex provides. He then goes through the eight or so steps to move from one to the other including file/directory changes and configuration updates. Next comes the look at performance differences between the two. Unsurprisingly Flex came out on top in every measurement he threw at it.

In addition to the new structure, the apparent improvement in performance is obviously welcome. This would likely be even more evident where I could leave more dependencies out, for example in API workloads. This obviously won't magically push Symfony/PHP into Golang or Node.js territory for raw API throughput, but for existing large code bases it could provide a low-effort boost.
