…need anything to re-render when it changes. That's why it's totally legal to grab this value in sidebar.vue or anywhere else that needs it. But I want to kind of future proof our app... and plan ahead for a future where…

…now that we're loading data via Ajax, we need a way to tell the user that things are loading... not that our server is on fire and they're waiting for nothing. Let's create a Loading component that we can re-use anywhere.

…it's not attaching any listeners or adding itself as a reference to anything in the code. In other words, this object is not attached or referenced anywhere in memory. Because of that, RepLogApp objects - and their Helper objects - should be eligible for garbage collection…

…southernUSStates to null: When you try it now, this of course prints "undefined". That makes sense: we're now passing null to the get() function. But what you can't see is that the southernUSStates object no longer exists... anywhere in memory! Why? In JavaScript…

…that function is its home. Before, when we weren't inside of any function, our two variables effectively became global: we could access them from anywhere. But now that we're inside of a function, the RepLogApp and Helper variables are only accessible from inside…

… We already know how! Back in CheeseListing, we've done this before with other filters. Anywhere in here, add @ApiFilter() with CheeseSearchFilter::class: Unfortunately, PhpStorm doesn't auto-complete that for me... so I'll copy the class name and add it on top manually…

…at the bottom, after executing validation, it gets back these "violations" and throws a ValidationException. This is a special exception that you can throw from anywhere to trigger the nice validation error response. So... let's go see it! At the browser, hit Execute and…

…if it's small. When you embed, the image doesn't need to be hosted publicly anywhere because it's literally contained inside the email. Next, I already mentioned that the style tag doesn't work in gmail... which means that our email will be…

…small HTML to bootstrap the Vue app... though I am doing one interesting thing: I'm passing a prop to Vue called entrypoint. I'm not using this anywhere... but it's a cool example: entrypoint is the URL to our documentation "homepage". In theory…

…test again: This time... it passes! Context builders are awesome. Though... they do have one downside: the dynamic groups are not reflected anywhere in the documentation. Refresh the docs... then open the GET operation for a single User. The docs say that this will return…

…it can! But we need to set this up in our bundle. Open the extension class, go anywhere in the load() method, and add $container->registerForAutoconfiguration(WordProviderInterface::class). The feature that automatically adds tags is called autoconfiguration, and this method returns a "template" Definition object…

…the block some default content, like with title: Yep, the browser tab's title is Welcome. Let's override that! At the top... or really, anywhere, add {% block title %}. Then say Read , print the title variable, and {% endblock %}: Try that! Yes! The page title changes…

…is this: everything is done by a service. If you learn to master services, you can do anything from anywhere in Symfony. There's a lot more to say about the topic of services, and so many other parts of Symfony: configuration, Doctrine & the database…

…Now that we have a proper class, we don't need to put handleFormSubmit() inside of render() anymore. Nope, we can access the props from anywhere as this.props. So, copy that function & the const, paste it in the class, turn it into a property,…

…thing to take-away here is that there is a try-catch block. This means that if you throw an exception from anywhere inside your application - like a controller or a service - it’s going to get caught by this block. And when that happens…

…were with us for episode 1, we did some pretty advanced error handling stuff at the bottom of this Application class. What we basically did was add a function that’s called anytime there’s an exception thrown anywhere. Then, we transform that into a…

…an exception happens. We haven’t talked about events yet, but this basically means that if you want, you can be nofitied whenever an exception is thrown anywhere in your code. Why would you do this? You might want to do some extra logging or…

…s added automatically to any page that has a valid HTML structure. That's why we didn't see it until we extended the layout file. Click anywhere on it to multiply the amount of information it gives you by 100! This is the profiler…
