Rewind ⏪ Symfony Messenger #37 To set up priority transport/queues with RabbitMQ & Symfony Messenger, we'll leverage the "exchange" and "queues" config. Let's learn exactly what these powerful options control & use them to make some messages more important than others! symfonycasts.com/screencast/mes…

Rewind ⏪ Symfony Messenger #36 Ever wanted to know how RabbitMQ/AMQP works? All that exchange and queue stuff? We've got you covered, with diagrams & a real-life example to track a message through the *entire* lifecycle in Symfony Messenger. Hey, Rabbit is fun! symfonycasts.com/screencast/mes…

Doctrine Inheritance #3 Ready for the next inheritance type? Single Table Inheritance is a slick way to store an entire entity hierarchy in one table. Let’s check it out! symfonycasts.com/screencast/doc…

Rewind ⏪ Symfony Messenger #35 Ready to up your queueing game? We're switching from the Doctrine Messenger transport to AMQP - specifically RabbitMQ. Yep, we're going to learn *all* about how RabbitMQ works and *love* the journey #Symfony symfonycasts.com/screencast/mes…

Rewind ⏪ Symfony Messenger #34 If a message in Messenger has multiple handlers, can you prioritize one handler over another? Yep! With the combination of priority transports and the interesting "from_transport" handler option. #Symfony symfonycasts.com/screencast/mes…

Doctrine Inheritance #2 🏭 When using Foundry factories with Doctrine inheritance, a few tricks can help keep duplication down. Let's go! symfonycasts.com/screencast/doc…

Rewind ⏪ Symfony Messenger #33 One of my favorite features of Messenger is how easy the setup is: Symfony automatically links a message to a handler by reading your type-hint. What if you need more control? Say hello to a message handler *subscriber* symfonycasts.com/screencast/mes…

New course alert! 🚨 Doctrine Inheritance #1 Want to share fields and behavior across multiple entities? Let’s start with the simplest form: the Mapped Superclass! symfonycasts.com/screencast/doc…

Rewind ⏪ Symfony Messenger #32 We've talked about command & event buses already. Now it's time to talk about the final type: a school bus! I mean, a query bus!? symfonycasts.com/screencast/mes…

Rewind ⏪ Symfony Messenger #31 Ready to see a cool Symfony services config trick? We can use auto-registration, sub-directories and tags to bind our command handlers *only* to the command bus and our event handlers *only* to the event bus. An optional, but geeky-fun step! #Messenger symfonycasts.com/screencast/mes…

Rewind ⏪ Symfony Messenger #30 Messenger has a few other built-in, but optional middleware that we haven't talked about yet. Let's look into the validation & doctrine_transaction middleware, talk about what each does and why you might (or might not) choose to use them #Symfony symfonycasts.com/screencast/mes…

Twig loads all extensions on each request - even unused ones. To keep things fast, push heavy logic into a Twig runtime. Pro tip: the runtime can be any service, not just something Twig-specific. 👉 symfonycasts.com/screencast/bun…

Rewind ⏪ Symfony Messenger #29 If Symfony has an EventDispatcher... and also Messenger is able to dispatch events... what’s the difference between EventDispatcher & Messenger? And when should I use one versus the other? Excellent question! symfonycasts.com/screencast/mes…

Rewind ⏪ Symfony Messenger #28 We’ve created an “event” and an “event handler”. Let’s finish this by dispatching that into our Messenger-powered event bus. Also: what happens if an event has *no* handlers? In a perfect world... that should be allowed. #Symfony symfonycasts.com/screencast/mes…

Rewind ⏪ Symfony Messenger #27 Event time! We’ll create our first “event” class for Messenger & corresponding event handler. What’s the difference between an event and a message? Let’s find out! #Symfony symfonycasts.com/screencast/mes…

Rewind ⏪ Symfony Messenger #26 We’re on our way to start using Messenger as an event bus! Let’s configure a separate bus service for this & see “named autowiring” in action: the system that allows you to autowire different message bus services in different situations #Symfony symfonycasts.com/screencast/mes…

When building bundles, not every class is meant to be used by end users. My preference is to mark those as "internal", and "hide" services so they don’t show up during container debugging. Here’s how I do it 👉 symfonycasts.com/screencast/bun…

Rewind ⏪ Symfony Messenger #25 When you deploy new code to your Symfony app, will your workers see the new code? Not until you restart them! Let's learn about a new command to restart *all* workers, some options to make sure workers don't run too long & a gotcha about updating messages symfonycasts.com/screencast/mes…

Rewind ⏪ Symfony Messenger #24 Deploy time! Messenger is delivering messages to our queue... but how do we run our workers on production? If your host doesn't handle it for you, Supervisor will. Let's get this wonderful tool set up, kill some workers & watch them restart #Symfony symfonycasts.com/screencast/mes…
