Help me with Livewire architecture

Hi folks

I'm venturing in Livewire for a webapp I am making. Due to the less common UI I am working on, I'm facing some struggles on how to organize livewire components.

The screen is composed of main content and a sidebar. The sidebar has 2 different components, that I want to navigate(think, pagination) independently. However, I also want to refresh or apply different filters when the main content changes in a certain way. Whats the best approach for this?

I'm using wire:navigate for the main menus, but I've noticed that when I visit a new page, my sidebar components loose their state (goes back to the first page). So I'm probably doing this wrong?

Happy to get any video recommendations that address this kind of problem when putting things together.

thanks in advance

It sounds like you're looking for a way to maintain the state of your sidebar components while also allowing them to react to changes in the main content area. Here's a general approach to structuring your Livewire components to achieve this:

  1. Main Layout Component: Create a main layout Livewire component that includes both the main content area and the sidebar. This component will serve as the parent component.

  2. Sidebar Components: Create separate Livewire components for each part of the sidebar that you want to navigate independently.

  3. State Management: To maintain the state of your sidebar components, you can use Livewire's built-in features like wire:key to preserve the component state across updates.

  4. Event Handling: Use Livewire events to communicate between components. When the main content changes in a certain way and you want to update the sidebar, you can emit an event from the main content component and listen for it in the sidebar components.

Here's a simplified example of how you might structure your components:

// MainLayoutComponent.php
class MainLayoutComponent extends Component
{
    public function render()
    {
        return view('livewire.main-layout-component');
    }
}

// SidebarComponentOne.php
class SidebarComponentOne extends Component
{
    protected $listeners = ['refreshComponent' => '$refresh'];

    public function render()
    {
        return view('livewire.sidebar-component-one');
    }
}

// SidebarComponentTwo.php
class SidebarComponentTwo extends Component
{
    protected $listeners = ['refreshComponent' => '$refresh'];

    public function render()
    {
        return view('livewire.sidebar-component-two');
    }
}

// MainContentComponent.php
class MainContentComponent extends Component
{
    public function someAction()
    {
        // Do something that changes the main content...

        // Then emit an event to refresh the sidebar components
        $this->emit('refreshComponent');
    }

    public function render()
    {
        return view('livewire.main-content-component');
    }
}

And in your Blade templates:

{{-- main-layout-component.blade.php --}}
<div>
    <livewire:main-content-component />
    <div class="sidebar">
        <livewire:sidebar-component-one wire:key="sidebar-component-one" />
        <livewire:sidebar-component-two wire:key="sidebar-component-two" />
    </div>
</div>

By using wire:key, you can help Livewire keep track of which component instances to preserve across renders. When you navigate to a new page, ensure that you're not re-rendering the entire layout component, which would reset the state of your sidebar components.

For more advanced state management, you might consider using Livewire's wire:model to bind properties between components or even using a global state management solution like Livewire's wire:entangle with Alpine.js for more complex scenarios.

As for video recommendations, you might want to check out the official Livewire screencasts on the Livewire documentation website, which cover a wide range of topics including component communication and state management.
