Even if you're developing bundles locally, you'll still need to install them with composer. Installation is a little different... but in a good way! We'll even stumble upon a hidden Symfony Flex feature 🌟

A bundle requires just one thing: a bundle class - the nerve center of your bundle. Let's create one, right after we fix a little quirk when working with multiple namespaces in the same project.

🚨 New course alert: Reusable Bundles 📦! Bundle development received a facelift in Symfony 6. Let’s check this out by creating a real, usable bundle that we’ll eventually push to Packagist for all to enjoy. Step 1: Initialize our bundle!

If a message fails repeatedly, instead of discarding it forever, let's send it to... the "failure transport"! Let's get this set up & learn how to find out exactly what advanced options each transport has. #Symfony

Time to look deeper at Messenger's retry settings & more advanced transport config. Retries have an exponential delay built-in to help overcome temporary failures. And of course, you can control all of this. #Symfony

Oh no! You sent your message to a transport/queue, but when it was handled (due to a temporary connection issue) an exception was thrown! Is it lost forever? Nope - Messenger automatically retries it. Let's see retries in action! #Symfony

With deep sadness, we share that Ryan Weaver — co-founder of SymfonyCasts, father, husband, beloved teacher, and friend — has passed away after a long and courageous journey with brain cancer.

Symfony messenger is all about dispatching "messages". But did you know that you can also wrap your message in an Envelope & attach extra config via stamps? Let's use a stamp to *delay* a message *and* see what stamps are added internally.

What happens if *part* of our handler fails? This is nothing new.... unless *some* of your handler is async. Let's route our second message to be async & learn some advanced features of message routing #Symfony

Half of the work for deleting an image in our app must happen now... but half could happen later. The solution? Split the command into 2 & dispatch from *within* the handler. We're breaking things down into smaller pieces to gain more control. #Symfony

Let's update our Messenger message class to hold the entity id instead of the entire object. That'll fix a bug and follow a nice rule: make your message as small as possible. Bonus: we'll start learning to fail gracefully & see retries in action #Symfony

A quick aside about Messenger, serializing Doctrine entities & (nerd-alert) the identity map! A fun look into a bug in our app and how Doctrine works internally. #Symfony

How can we *consume* messages from the queue asynchronously? By running Symfony’s worker command: php bin/console messenger:consume Dispatching new messages and watching them get handled async automatically? Gorgeous! https://t.co/Kb9LYxOKU5

Say hello to Messenger transports: the key system that allows you to send message to a queue instead of handling them immediately. Let’s get the Doctrine transport set up, route some messages there and see what it all looks like in the database! #Symfony https://t.co/oHuVytOWhO

We’re putting messenger to work, refactoring a controller down to 2 lines! That’s thanks to a new command class, a new handler and the debugging superpowers of debug:messenger... when I mess up #Symfony https://t.co/2xqyZdp8te

The command (message) class and handler inside Messenger are a team: the message class holds *whatever* data you need to pass around while the handler uses that info (+autowired services) to do the work! It’s refreshingly... simple. #Symfony https://t.co/U7DbTYvybz

Let’s get to the heart of messenger! Create a message class, a handler class, *link* them together, and dispatch to the bus. Oh... and we’ll explain what the heck a “command bus” *is* in the first place. #Symfony https://t.co/Xnag70gCE3

Symfony Messenger! We know you’re going to *love* working with this component... and the app we’ve built with it ? #Symfony #queues #async #cats #hashtags https://t.co/LT59dlkgRX

We've successfully pushed our English translations up to @Crowdin. Merci beaucoup! now, let's automatically translate and pull them back down!

For a course about translations, we really haven’t done much "translating" yet. That’s kinda important! Symfony has integrations with a few different Translation Provider services. Let’s look at @Crowdin, and see how it works!
