Was wire:ignore removed from Livewire 3?

Yes, the wire:ignore directive was removed in Livewire 2. It was replaced with the wire:ignore.self directive in Livewire 3.

The wire:ignore.self directive allows you to ignore updates to the component itself, while still allowing updates to its child components.

Here's an example of how to use wire:ignore.self in a Livewire component:

<div>
    <input type="text" wire:model="name">
    <button wire:click="updateName">Update Name</button>
</div>

class MyComponent extends Component
{
    public $name;

    public function updateName()
    {
        // Perform some logic here
    }

    public function render()
    {
        return view('livewire.my-component')->layout('layouts.app');
    }
}

In this example, the wire:ignore.self directive is not used, so any changes to the input field will trigger a Livewire update. If you want to ignore updates to the input field, you can use wire:ignore.self like this:

<div>
    <input type="text" wire:model="name" wire:ignore.self>
    <button wire:click="updateName">Update Name</button>
</div>

Now, changes to the input field will not trigger a Livewire update, but clicking the "Update Name" button will still trigger the updateName method.

I hope this helps! Let me know if you have any further questions.
