Alpine.js

Alpine.js is the shortest path from Laravel rule strings to interactive browser feedback. The package supports both field-level directives and a form-scoped validation() helper.

Register the adapter#

import Alpine from 'alpinejs';
import registerAlpine from 'laravel-client-validation/alpine';

window.Alpine = Alpine;
registerAlpine(Alpine);
Alpine.start();

If you load the browser bundle through @clientValidationAssets, the package auto-registers Alpine integration when Alpine boots.

Validate individual fields#

<input name="email" x-validate="'required|email'">
<input name="username" x-validate.live="'required|alpha_dash|min:3'">
<input type="password" name="password" x-validate.submit="'required|min:8|confirmed'">

x-validate validates on blur by default. .live adds debounced input validation and .submit blocks form submission until the field passes.

Manage a full Alpine form#

<div x-data="validation({
    rules: {
        email: 'required|email|unique:users,email',
        password: 'required|min:8',
        password_confirmation: 'required|same:password',
    },
    messages: {
        'password.min': 'Use at least eight characters.',
    },
})">
    <form @submit.prevent="submit(async (payload) => await fetch('/register', {
        method: 'POST',
        headers: { 'Content-Type': 'application/json' },
        body: JSON.stringify(payload),
    }))">
        <input x-model="form.email" @input="validateLive('email')" @blur="validate('email')" name="email">
        <p x-show="hasError('email')" x-text="error('email')"></p>

        <input type="password" x-model="form.password" @blur="validate('password')" name="password">
        <p x-show="hasError('password')" x-text="error('password')"></p>
    </form>
</div>

The helper keeps touched state, per-field errors, and debounced remote validation in one Alpine object. Use stateClass(field) when you want to map the package validity state into your own utility classes.

Cross-field and remote rules#

Rules such as same, different, required_if, and unique work best when every sibling value lives in the same form object so Alpine always passes the latest state into the validator.
