Global Loading Indicator - FilamentPHP Glow

Why?

Certain operations in Filament may experience prolonged loading times, for example when applying filters to a table. The following code snippet introduces a renderhook to the footer, coupled with an Alpine listener to display a loading message.

Ensure to set the timeout to a sufficiently high value to prevent the message from appearing unnecessarily for small requests.

1$panel
2    ->renderHook(
3            'panels::footer',
4            fn (): View => view('zeus-tartarus::hooks.footer'),
5    )

 1<div
 2        x-cloak
 3        x-show="$store.isLoading.value"
 4        class="fixed max-sm:bottom-4 sm:top-4 left-1/2 -translate-x-1/2 z-[6000001]"
 5>
 6    <div
 7            class="flex gap-2"

14    <script>
15        document.addEventListener('alpine:init', () => Alpine.store('isLoading', {
16            value: false,
17            delayTimer: null,
18            set(value) {
19                clearTimeout(this.delayTimer);
20                if (value === false) this.value = false;
21                else this.delayTimer = setTimeout(() => this.value = true, 2000);
22            }
23        }))
24        document.addEventListener("livewire:init", () => {
25            Livewire.hook('commit.prepare', () => Alpine.store('isLoading').set(true))
26            Livewire.hook('commit', ({succeed}) => succeed(() => queueMicrotask(() => Alpine.store('isLoading').set(false))))
27        })
