How to add a confirmation dialog with Livewire

Livewire released a wire:confirm HTML directive that makes it easier than ever to add a confirmation dialog before performing an important or dangerous action. The confirm directive will trigger a native browser Window confirm modal, and once the user confirms, Livewire will trigger the intended event.

Here's the rough JS equivalent:

if (window.confirm("Are you sure you want to delete this user?")) {
  // Proceed only after the user has confirmed
}

How do you do this with Livewire? Really easily!

For a simple confirmation with a "Cancel" and "OK" button, you can use the wire:confirm like so coupled with an event like wire:click:

<div>
    <h2>Danger zone</h2>
    <button
        type="button"
        wire:click="delete"
        wire:confirm="Are you sure you want to delete this project?"
    >
        Delete this project
    </button>
</div>

When you click the button, Livewire will trigger a native browser confirmation modal:

Things get a little more interesting if you want the user to type something out to confirm that they intentionally want to do something destructive, for example, delete a repository on GitHub:

<div>
    <h2>Danger zone</h2>
    {{-- ... --}}
    <button
        type="button"
        wire:click="delete"
        wire:confirm.prompt="Are you sure?\n\nType DELETE to confirm|DELETE"
    >
        Delete this project
    </button>
</div>

Note the |DELETE which lets Livewire know the expected prompt to match.

Clicking the button will prompt the user with a prompt() modal, asking them to type "DELETE." If the user's input matches, it will trigger the delete() method on the Livewire component.

Taking this a little further, you could make the confirmation word or phrase match a dynamic value on the component. For example, perhaps you want to make the user type the project name to confirm:

<div>
    <h2>Danger zone</h2>
    {{-- ... --}}
    <button
        type="button"
        wire:click="delete"
        wire:confirm.prompt="Are you sure?\n\nType &quot;{{ str($project_name)->upper() }}&quot; to confirm|{{ str($project_name)->upper() }}"
    >
        Delete this project
    </button>
</div>

One caveat is that the text matching is case-sensitive, so I thought it would be easiest to make it all uppercase. If you want to use quotes like I am demonstrating, you'll need to use HTML entities in the wire:confirm attribute.
