[7.x] Once Blocks

[taylorotwell]

Proof of concept for @JeffreyWay ...

Component content here...

@once
    <script>
        This will only be included in the template once even if component is rendered multiple times.
    </script>
@endonce

[JeffreyWay]

Wew!

Woop Wooop!

‪it would benefit a lot having a key 🔑 and dependencies so it’s rendered in the right order.
Also version, for cache busting

‪This problem has already been solved in Wordpress. Check this out

@eduardoarandah I think the <script> was just a random example. I don't think it's meant for including your assets at all.

I ran into a use-case today where this would have came in handy!

[GrahamCampbell]

This will be available in Laravel 7.25.0, tomorrow. ;)

Here's an actual use case:

This component renders to a list of receipts. The for the receipt has to be rendered once in the entire page while the component itself can be used multiple times.

Ha, talk about timing! This will come in really handy for something I’m currently building!

[marchampson]

Great job - I can see this being used a lot.

I think every dev which uses components already has your own implementation of push once at this time. Almost all based on this sw

I love this. I can also see the ability to use this like the @push() but a @pushonce('scripts') directive.

[epalmans]

@brenjt agree #30104 :-)

[gauravmak]

Is the documentation updated already?

[driesvints]

@gauravmak no but feel free to send in a PR. Otherwise I'll try to do so when I'm back from vacation.

[JunaidQadirB]

I use @stack @push a lot in my blade components. It will be really useful for my use-case. Awesome!

@driesvints @gauravmak I just sent a PR on updating docs laravel/docs#6255
