In short, you can use the constructor, inject directly to a public property or you can use a two flavours of injection via a method. Short example: # config/services.yaml services: App\Service\MyFancyService: calls: - setLogger: ['@logger'] class MyFancyService { private LoggerInterface|null $logger = null; public function setLogger(LoggerInterface $logger): void { $...

I did a talk about it at Symfony World 2021 where I explain how and why it works. I spent a lot of time on the content and the recording, one can still watch the replay. Since that talk, I've been deploying a few applications on Bref using runtime/bref. I really like building and deploying applications this way. I did a small test if there is any performance difference between using Bref's FPM layer compared to using Bref with the runtime component. I te...

It helps me with race conditions, it makes my code simpler and my application more reliable. I'm using it to fix all kinds of problems and I've noticed that I use a few different methods. This article will try to explain these methods or "strategies". My hope is to make life simpler for everybody else to implement Symfony Lock component with Messenger. No two messages handled at the same time This strategy is the simplest one and is good ...

At the time we could never have imagined how popular it would be. In this first year we had over 1.5 million downloads over all packages. The core package alone has been downloaded more than 500.000 times. The story behind the project is simple. We wanted an AWS client that was fundamentally different from the official one. The big features are all described on async-aws.com, but in short: we use small p...

It has so many features and is super flexible. I want to highlight one of these features in this small post: Failures and retries. Over in the Symfony docs failures and retries are briefly mentioned and it explains what values you can configure. However, it does not give a good recommendation for what values to use. The simple answer to "What values should I use?" is "It depends". Depending on what your application requirements are these values wil...

Most of them are small microservice applications that are rarely updated with new features. We've installed and configured the applications so we can run Blackfire's profiler on each of these applications. Blackfire's internal architecture allows us to install the profiler in a clever way, compared to other profilers I've tried. This article will go over how to install Blackfire when you have multiple serve...

I was super excited about this and I started to try it out. But I quickly noticed that it was a little buggy when you started with a "real world" application. It worked fine for small hello world apps. One example of such issues are with class_alias, which is a common practice to use by libraries that want to provide backwards or forwards compatibility. If you were trying to preload a file like that, then PHP-FPM failed to start with ou...

How hard can that be? It was way more tricky than I thought, especially since Im not used to the Node ecosystem. So here I am sharing my research and result. I hope it can be useful. Requirements I wanted to use javascript because there is native support for Node on AWS Lambda. I am also under the impression that there are tonnes of great node libraries that help me optimize images. Node8 is soon to be d...

Symfony's HTTP client is asynchronous by default. Using asynchronous anything is strange in PHP but there is no magic. The asynchronous part in any PHP HTTP client is achieved with help from cURL. Asynchronous by default means that we are only making the HTTP request when we actually need data from the response. This allow us to start multiple requests and let cURL execute them i...

The Symfony Messenger component was released around a year ago and I've loved it since. In the past few weeks we've been deploying applications on AWS Lambda. Going serverless is super cool since you can scale up and down, it is cheap bla bla bla. The major selling point to me is that you don't need to care about dev ops once it all up and running. We've been using Bref and I can highly recommend it. When running your ap...

When migrating our applications to use Bref we realized that we need a non-standard php-extension. With "non-standard" I mean that the extension is not included by default by Bref. With some help I manage to make every thing work as I wanted it to. Here is what I did: I cloned the Bref repository to be able to build my own image. Then I added the NewRelic extension and config to php.Dockerfile in the /runtime/php directory. ## Install NewRelic RUN \ curl...

It basically allows you to configure the browser to load the webpage first and then add the correct fonts when they are loaded. Note that you can only add font-display: swap; on @font-face. That is an issue because we are using Google fonts. So I downloaded the CSS file from Google fonts and stored it locally. Then I added font-display: swap; on all @font-face like: @font-face { font-family: 'Roboto'; font-style: no...

I was of course thrilled by the news and started to work on multiple PRs to make the component support state machines. It was a really cool experience working with the Symfony community and discussing everything from Petri nets to minor code optimizations. I often get questions how to work with the Workflow component and questions like "what should I do in this really specific scenario". One question I do ge...

One of them asked me a question, that the answer was not obvious. His use case was that he wanted to use Symfonys Access Control configuration to restrict access in his application. But he also wanted to configure the rules dynamically. Since all the configuration in Symfony is cached with the container for performance reasons, we could obviously not allow a use a database to somehow "print" new configurati...

We ran some tests to find out. An improved router A few days ago we received the fantastic news that the Symfony router had been improved significantly. Of course we wanted to see how the changes would affect our application, so we decided to test it against our own routes. If you somehow missed the news you can read the official announcement. If you want to know how the new router works, read Nicolas Grekas post where he div... Fri, 02 Feb 18 15:06:47 +0000 http://engineering.eneba.com/blog/symfony-route-test.html http://engineering.eneba.com/blog/symfony-route-test.html It has been great many years since Symfony 2.0 was released. 2.0 did not have as many great features as Symfony 4.0, but it was flexible and you could still accomplish what ever you want. I've just found out one small thing that Symfony 4.0 does way better that 2.0. EDIT: This is not new to Symfony 4.0. It was a feature already in 2.7. Long long time ago I had the need for creating a Symfony command that sends emails to users given some criteria. So I wrote my command and set up my cron job and ...

Composer's documentation is great but a bit short, that is why I write this blog post. Composer assumes that all packages are using Semver. It is an easy version schema that consists of a major.minor.patch version. A major version breaks backwards compatibility, minor version introduces new features and patch versions are bug f...

This is very helpful when you quickly want to find a controller or when you got an exception. // /config/packages/framework.yml framework: ide: "phpstorm://open?file=%%f&line=%%l" You could also do this trick locally on your machine instead. That will not conflict with other developers in your team and it will work for all your projects. ; php.ini xdebug.file_link_f...

When I inspect the queries in the Symfony profiler I can see that Doctrine is fetching objects I have not requested. To give you a clear image of the problem I'll show an example of the database mapping. class User { /** * @ORM\Column(name="id", type="integer") * @ORM\Id * @ORM\GeneratedValue(strategy="AUTO") */ private $id; /** * @ORM\OneToOne(targetEntity="Res...
