Dans l'interview du jour, @mtarld.bsky.social nous parle de Streaming et Mercure, revient aussi sur les 20 ans de Symfony, et nous dit pourquoi le streaming ne devrait plus être une "technique avancée" mais une évidence. Venez au Forum PHP 2026 pour en savoir plus ! buff.ly/ADpdSKe

« Dépréciations Symfony : de l’angoisse à l’opportunité », la conférence de @mtarld.bsky.social à revoir sur le site de l'AFUP
afup.org
Dépréciations Symfony : de l’angoisse à l’opportunité
Les messages de dépréciation s’entassent petit à petit dans vos logs, et la perspective de chaque version majeure vous inquiète ? Et si les dépréciations n’étaient pas un frein, mais plutôt une force pour votre code ? Dans ce talk, on va découvrir comment Symfony gère les dépréciations avec élégance, pour vous préparer en douceur à chaque nouvelle version majeure, sans stress ni panique. Grâce à un processus rigoureux et des outils bien pensés, vous apprendrez à : * détecter et comprendre les dépréciations qui concernent votre projet, * mettre en place une stratégie de migration progressive et maîtrisée, * utiliser les outils fournis par Symfony pour anticiper les ruptures, * profiter des dépréciations comme d’un levier pour améliorer la qualité et la pérennité de votre code. On plongera aussi dans des exemples concrets de migration entre deux versions majeures, pour montrer que la montée de version est moins un saut dans le vide qu’un chemin balisé. L’objectif ? Vous faire adopter une approche sereine et proactive des dépréciations, pour que chaque nouvelle version de Symfony soit une opportunité d’évolution, et non une source d’angoisse.

💡 Your Symfony pages don't change between deploys? Then they probably don't need Symfony at runtime. A fresh tale from the changelog by @mtarld.bsky.social 👇 baksla.sh/blog/when-sy...
baksla.sh
When Symfony pages don't need Symfony
5ms to render a Symfony page. 0.2ms to serve it as a static file. 25× faster, same response. Time to put the kernel on a strict diet.

As of #Symfony 7.4, functional tests’ error rendering will finally get you straight to the point with a beautiful, concise output 🥳 Especially useful when doing large refactorings that make dozens of such tests fail while progressing. Before/After 👇

I didn’t discover AGI but that’s still a great news: #Symfony #JsonPath is fully compliant to the RFC 9535! 🎉 Both using JSON as a plain-string or as a #PHP resource (it’s using @mtarld.bsky.social JsonStreamer under the hood for max speed!). Time to clean-up the diff and send a PR 😉
