HTTP compression in Symfony apps (Kévin Dunglas)

Compressing HTTP responses can significantly improve the performance of your Symfony applications. But you still need to find your way through the jungle of standards and formats. In this presentation, we'll discover how HTTP compression works, the different formats supported by modern web browsers (deflate, gzip, Brotli, and the brand new Zstandard), and how to use them correctly with Symfony. We'll also look at which formats to compress, which not to, when to use dynamic compression, and when (and how) to pre-compress responses that can be compressed for even better performance.

From Translations to Multi Dimension Entities (Alexander Schranz)

Content management is more than just adding a text editor to your project. Initially, you may only need a basic text editor for your Entity. However, as your project grows, you might require support for multiple languages, and when drafting or versioning come into play, things can get tricky. In this talk, I will provide a quick introduction to different ways of data modeling and the libraries available to meet these needs. I'll also share a brief history of Sulu's content storage and explain why we decided to redesign the entire content storage system for a better future. You'll learn how to evolve from a simple Doctrine entity to a translatable entity, and finally, to a multi-dimensional entity that supports multiple languages, drafting, versioning, and more. These concepts are reusable even if you're not using our beloved CMS.

Crafting Hybrid PHP-Go CLIs with Symfony Console (Antonis Kalipetis)

Discover how to bridge the gap between legacy PHP code and the performance of Go in hybrid CLI development. Using the Symfony Console library, you'll see how we blend these two languages in the Upsun CLI, embedding the Legacy Platform.sh PHP CLI within Go for seamless functionality. This approach not only enhances performance but also preserves backward compatibility, saving time while migrating from the older PHP-based CLI to the new, faster Go implementation. You'll learn how we maintain intuitive command routing, make it invisible to users, and tackle authentication across both platforms. This talk is perfect for those looking to modernize their tools without starting from scratch.

Symfony UX: 2024 Highlights & What’s Next (Simon André)

Building a Fraud Prevention component using Symfony (Moritz Schuh)

Online fraud and abuse poses a serious risk to all digital businesses and having preventive measure in place has become indispensable. In this talk we will be looking at how to build a Symfony application tasked with detecting and preventing malicious activities such as credit card fraud, automated registrations and abuse of free resources. Our application will collect data from different sources and provide a RESTFul API to other services to guide access to resources, trigger verification requests and block suspicious activities.

A brand-new way to serialize data in Symfony (Mathias Arlaud)

Serialization plays an essential role in any information system, and particularly in the context of a web application, as it is one of the pivots of the HTTP request/response cycle. That's why Symfony's Serializer component is one of the most critical for our applications. Needs evolve, and since its creation, this old component has found itself confronted with new problems and has in some ways reached its own limits. That's why it's now necessary to completely rethink the way we serialize data in the Symfony ecosystem. So let's take a look at two Symfony component drafts: the JsonEncoder and the ObjectMapper, and how they interact to provide a brand-new way of serializing data.

Flexibility in the Face of Uncertainty (Wachter Johannes)

In this forward-thinking talk, I'll take you on a journey through the integration of AI in Symfony projects. Drawing from our real-world experiences, I'll demonstrate how to build adaptable AI systems that can withstand the ever-shifting landscape of AI technologies and regulations.

Attendees will leave with a solid understanding of streamlining their development workflows and improving collaboration with their colleagues.

Greener code with Symfony (Michelle Sanver)

As software engineers it is sometimes too easy to forget the impact that our code has on the environment. We build for changeability, speed and hopefully quality, but we forget about sustainability. The time to act is now. It is time for us to take responsibility and to write more sustainable tech. In this talk I will talk about things we can do to write more energy efficient code. I will also talk about hosting your code more sustainably. And last but not least… I will share the software architecture needed to build greener applications using Symfony Messenger.

Refactor your code - refactor yourself (Peter Dietrich)

Looking at old legacy code, you usually know "a better way to do it" by now. But did you ever look at "the code in your mind"? Let's go through a helpful mindset for refactoring projects and apply some principles of refactoring to yourself. This talk will give you a better understanding of how you and your brain evolved from index.php to a complete fully grown application - and what parts of your brain still run legacy code.

Cutting-Edge Symfony Pipelines with Dagger (Paul Dragoonis)

I truly believe Dagger is the next evolution of CI/CD implementation. Myself, as a subject matter expert in CI/CD, I spent years building the perfect system to mitigate challenges we face at a tech level and business level. Now along comes Dagger, created by Solomon, the founder of Docker, and it makes so many challenges disappear, by design, and opens up so many new possibilities along the way. In this talk I'll be your guide in a deep dive into Dagger-land, demonstrating how to strategically start integrating this into your existing projects and start benefiting from the awesomeness.

Who did that? Auditing data changes at scale (Sebastian Plagemann)

As your application evolves from a side project into a serious business, you will likely encounter situations where you, your support team, or even your customers question why certain configurations changed, why information is incorrect, or why data seemingly vanished "on its own." Understanding and effectively managing these issues is crucial to maintaining the integrity and reliability of your application. This talk will explore various strategies for auditing data changes in Symfony applications. We will discuss where to begin and what factors to consider as the volume of data increases.

Symfony Mapper component (Antoine Bluchet)

Mapping is something that you see in many frameworks over the web in every programming languages. Doctrine, for example, has a quite complex mapper to transform the relational database representation to your well-known entity. After covering the history behind years of discussion and research by the Symfony community, we'll study the needs for such a component in Symfony. We'll analyse how different it is from the Symfony Serializer, and what are the solutions popular frameworks on the Web offer. At least, we'll showcase the new Mapper component and its application from API design to day to day use cases.

Demystifying Dependency Injection in Symfony (Dave Liddament)

The Dependency Injection Component is a key part of all Symfony applications. It helps developers write decoupled and maintainable code. In this beginner-level talk, we will explore the following: - The principles of Dependency Injection - Setting up and configuring the Symfony service container - Using Attributes for service configuration By the end of this session, you'll have a solid understanding of how to implement DI effectively, ensuring your Symfony applications are scalable, maintainable, and easy to test.

42 best practices for Symfony, a decade later (Tugdual Saunier)

We are in March 2013. Symfony 2.2 has just been released, PHP 5.5 is around the corner and I give my first public talk during a SymfonyLive: “42 best practices for Symfony” (in French). 10+ years later a lot of things changed for Symfony, for PHP but also regarding development in general. Let’s take a moment to look back at those best practices and see which one are still relevant, obsolete or now completely wrong. This would be a nice opportunity to reflect on the evolutions our ecosystem experienced over the last decade.

Carry out the best audit for your client (Marie Minasyan)

When you're faced with auditing an application or a set of applications, it's easy to get lost and forget the big picture. Let's discuss which tools are best suitable for every part of the audit, which aspects of the stack should be audited and how to proceed. Join me in finding out which traps to avoid and how to best carry out your next audit.

Platforms & Frameworks Eat Culture for Breakfast (Nigel)

As tech leaders we like to think we’re responsible for driving organisational and cultural change, but in most cases, we’re just catching up to the possibilities created by new kinds of software, and re-forming our engineering organisations to take advantage of them. Organisational dynamics are critical, but success at enabling fast flow is ultimately dependent upon how well your tech stack enables it. It’s technology that drives progress. In this talk Nigel will take a tour through some history of the DevOps movement, findings from a decade of State of DevOps Reports, his experience driving change at large and small companies, discuss some relevant inflection points in software and how they influence organisational dynamics, argue that the dominance of “culture” topics divorced from technological progress fails to advance our industry, and demonstrate how platform and framework adoption drives the best kind of cultural changes.

Bulletproofing for Black Friday (Thomas di Luccio)

The holiday season, especially Black Friday, is a goldmine for e-commerce apps—but only if they can handle the traffic. When the surge hits, unprepared applications buckle under pressure, leading to frustrated users and crashed servers. Been there, done that... In this talk, I’ll share some e-commerce horror stories from the trenches and show you how to avoid becoming one. We’ll dive into a proven roadmap to reliability using production cloning, traffic generation, and real-time observability. With these strategies (plus a dash of your magic), you’ll have the perfect recipe to ensure your app withstands the holiday rush—and you can relax, knowing your system won’t let you down

The missing Gotenberg Bundle. Components, Assemble! (Adrien Roches, Hubert Lenoir)

Since wkhtmltopdf was deprecated, it is difficult to find an easy to use / setup library to generate PDF's. Amongst the existing solutions, we chose to focus solely on Gotenberg. The existing SDK did not match our needs as it provides only static classes, so we decided to give a try and create ourselves a brand new Bundle with the DX possible for Symfony Developpers & PHPStorm users. From the fast HttpClient to the forgotten Webhook, let's see how existing components can help us to make PDF generation fast and easy to use. To do so we had to ask ourselves a few questions which we will cover together ! How do we expose a friendly, yet semantic configuration ? How to ensure great auto-completion for ease of use ? What needs to be done to have a proper Profiler ? How to keep memory efficiency by leveraging the HttpClient ? How to make the asynchrone generation easy ? Come and discover how generating PDF's is now as easy as using twig !

Strict PHP (Alexander M. Turek)

Its loose type system and implicit type casts make PHP a perfect programming language for beginners. However, if we rely on those features heavily, we will eventually end up with a codebase that is hard to control and maintain. In this session, Alexander will open up his toolbox and show how a stricter way of programming PHP applications helps him to not lose pace when applying changes to PHP applications.

GraphQL, REST or RPC? Making the choice! (Rob Allen)

When you've been tasked with creating an HTTP API, the fundamental decision you need to make is which architecture to choose. Should your API be RESTful? What about GraphQL? or RPC? In this session, I'll explain the choices and how each works. We'll then look at their strengths and weaknesses in order to help guide your decision. By the end of this talk, you'll be well-placed to choose the right API architecture for your project.

The Role of Empathy in Technical Writing (Kemi Elizabeth Ojogbede)

It’s easy to assume that our users are experts when writing documentation. But technical writing without diagrams, code examples, videos, screenshots and more can ostracise a large chunk of users who are simply searching for help when using your product. When writing technical documentation, empathy allows us to imagine ourselves as the reader: a junior developer who just started on the job, a sales manager who needs more information for a client deck, a member of the customer success team helping a client on a video call. When we’re able to understand that our docs form the foundation of knowledge for a wide range of users, we’re able to write in a manner that positively impacts all. We may be writing about logical concepts, but our approach can definitely benefit from a bit of heart. This talk will break down the vital role empathy plays in the process of writing technical documentation for users from all business backgrounds.

Modern Approaches to Web Security: Stateless CSRF Protection Explained (Nicolas Grekas)

Running Symfony in a Multi-Process Container (Anne-Julia Seitz)

The deployment scenario for PHP looks a little different than for other languages like Go or Ruby that have embedded webservers. The classic stack of NGINX/Apache + php-fpm doesn't perfectly fit in the container world. Some solution providers, like DigitalOcean or certain Azure products, only allow for single containers to be deployed. In this talk, we'll explore ways other people have solved this, like FrankenPHP, Framework-X , and others. For production deployments, there is k8s, swarm, compose, and running everything in one multiprocess container. These single containers could be orchestrated with systemd, supervisord, or Runit. We'll talk about the benefits and downsides of these solutions, compare them with the choice we made for our last project, s6-overlay, show off the s6-cli project I developed for this purpose and talk about recipes for running database migrations, cronjobs and a few more.

Symfony Authentication: What's next? (Robin Chalas)

The Security component has changed a lot in the past few years. From Authentication Listeners to Guard and finally the Authenticator Manager system, Symfony now has the most robust infrastructure ever to support most if not all modern, industry-standard Security protocols. The community started building on these new foundations by introducing an AccessTokenAuthenticator and kept improving it since then, notably through adding more token handlers for well-known authentication protocols. That's pretty cool already, but what should we expect next? How far will we take it? In this talk, I'm going to put my Security maintainer hat on to answer these questions and share some insights about what's going on in this critical part of our beloved framework.

Resurrecting the Dead (Juliette Reinders Folmer)

Have you ever considered what would happen when a popular open source package is abandoned? Now, what about when that package is one of your essential dependencies?
