wire:bind is a directive that dynamically binds HTML attributes to component properties or expressions. Unlike using Blade's attribute syntax, wire:bind updates the attribute reactively on the client without requiring a full re-render.

If you are familiar with Alpine's x-bind directive, the two are essentially the same.

Basic usage

<input wire:model="message" wire:bind:class="message.length > 240 && 'text-red-500'">

As the user types, wire:bind:class reacts to the message length and applies the class instantly on the client.

Common use cases

Binding styles

<div wire:bind:style="{ 'color': textColor, 'font-size': fontSize + 'px' }">
    Styled text
</div>

Binding href

<a wire:bind:href="url">Dynamic link</a>

Binding disabled state

<button wire:bind:disabled="isArchived">Delete</button>

Binding data attributes

<div wire:bind:data-count="count">...</div>

Reference

wire:bind:{attribute}="expression"

Replace {attribute} with any valid HTML attribute name (e.g., class, style, href, disabled, data-*).

This directive has no modifiers.
