A powerful validation package that brings Laravel validation rules to the client-side. Validate forms in real-time using the same rules you know from Laravel — works with **any backend** or as a standalone NPM package.

Features
--------

[](#features)

- **104 client-side rules** — Comprehensive coverage of Laravel validation rules
- **5 remote rules** — Server-side AJAX validation for `unique`, `exists`, etc.
- **TypeScript declarations** — Full type definitions for IDE autocompletion
- **Laravel 12/13 support** — Compatible with the latest Laravel versions
- **Livewire v3 & v4** — Automatic version detection and optimized integration
- **Filament v3 & v5** — Panel plugin with field-level validation
- **Backend-agnostic** — Use with Laravel, Django, Express, Rails, or any backend
- **Multiple integrations** — Alpine.js, Livewire, Filament, Vanilla JS, React, Vue
- **Real-time validation** — Instant feedback on blur, input, or submit
- **FormRequest support** — Extract rules from existing Laravel FormRequest classes
- **Validation hooks** — `beforeValidate`, `afterValidate`, field-level events
- **Bail support** — Stop on first failure per field with `bail` rule
- **Batch validation** — Validate multiple fields in a single AJAX request
- **Rate limiting** — Built-in request throttling for AJAX validation
- **Zero configuration** — Works out of the box with sensible defaults
- **Tree-shakeable** — ES module subpath exports for minimal bundle size

Quick Start
-----------

[](#quick-start)

### Option A: Laravel Package (Composer)

[](#option-a-laravel-package-composer)

```
composer require mrpunyapal/laravel-client-validation
php artisan client-validation:install
```

### Laravel Boost

[](#laravel-boost)

If your Laravel project uses [Laravel Boost](https://laravel.com/docs/13.x/boost), this package ships a third-party Boost skill for package-aware code generation and debugging.

Install Boost if needed:

```
composer require laravel/boost --dev
php artisan boost:install
```

If Boost is already installed in the app, refresh package-provided skills after adding or updating this package:

```
php artisan boost:update --discover
```

When skills are enabled, Boost can install the `laravel-client-validation-development` skill and guide AI agents toward the package's recommended Blade, Alpine, Livewire, Filament, and remote-validation patterns.

### Option B: Standalone NPM Package

[](#option-b-standalone-npm-package)

```
npm install laravel-client-validation
```

Import only what you need:

```
// Core engine only (no framework dependency)
import { LaravelValidator, RuleRegistry } from 'laravel-client-validation/core';

// Alpine.js adapter
import { createAlpineValidator } from 'laravel-client-validation/alpine';

// Vanilla JS adapter
import { createFormValidator } from 'laravel-client-validation/vanilla';
```

### Option C: CDN / Script Tag

[](#option-c-cdn--script-tag)

```

  const validator = new LaravelClientValidation.Validator({
    rules: { email: 'required|email' }
  });

```

---

Usage with Alpine.js
--------------------

[](#usage-with-alpinejs)

### Simple Field Validation

[](#simple-field-validation)

```
{{-- Validate on blur (default) --}}

{{-- Validate as you type --}}

{{-- Validate on form submit only --}}

{{-- Bail on first failure --}}

```

### Complete Form Component

[](#complete-form-component)

```

        Submit

```

### Available Methods in `validation()` Component

[](#available-methods-in-validation-component)

MethodDescription`validate('field')`Validate a single field`validateAll()`Validate all fields`submit(callback)`Validate then call callback if valid`error('field')`Get first error for field`hasError('field')`Check if field has errors`hasErrors()`Check if any errors exist`isValid()`Check if form is valid`clearError('field')`Clear errors for field`reset()`Reset form to initial state---

Usage with Livewire
-------------------

[](#usage-with-livewire)

> Supports both Livewire v3 and v4. Version is detected automatically.

### Using the `x-wire-validate` Directive

[](#using-the-x-wire-validate-directive)

```

        {{-- Livewire v4: use wire:model.live for real-time sync --}}

        Submit

```

### Using the PHP Trait

[](#using-the-php-trait)

```
use Livewire\Component;
use MrPunyapal\ClientValidation\Livewire\WithClientValidation;

class CreateUser extends Component
{
    use WithClientValidation;

    public string $name = '';
    public string $email = '';
    public string $password = '';
    public string $password_confirmation = '';

    protected $rules = [
        'name' => 'required|string|min:2|max:50',
        'email' => 'required|email',
        'password' => 'required|min:8|confirmed',
    ];

    protected $messages = [
        'email.required' => 'Please enter your email address',
        'password.confirmed' => 'Passwords do not match',
    ];

    public function render()
    {
        return view('livewire.create-user');
    }
}
```

In your Blade view:

```

```

### Livewire Events

[](#livewire-events)

```
protected $listeners = [
    'client-validation-error' => 'handleClientError',
    'client-validation-cleared' => 'handleClientCleared',
];

public function handleClientError($data)
{
    // $data = ['field' => 'email', 'errors' => ['The email field is required.']]
}
```

---

Usage with Filament
-------------------

[](#usage-with-filament)

### Register the Plugin

[](#register-the-plugin)

```
use MrPunyapal\ClientValidation\Filament\ClientValidationPlugin;

class AdminPanelProvider extends PanelProvider
{
    public function panel(Panel $panel): Panel
    {
        return $panel
            ->plugins([
                ClientValidationPlugin::make()
                    ->enableRemoteValidation()
                    ->validationMode('live'),
            ]);
    }
}
```

### Add Validation to Fields

[](#add-validation-to-fields)

Use the `HasClientValidation` trait on your custom Filament fields:

```
use Filament\Forms\Components\Field;
use MrPunyapal\ClientValidation\Filament\HasClientValidation;

class MyField extends Field
{
    use HasClientValidation;
}
```

Or use the pre-built `ClientValidatedField`:

```
use MrPunyapal\ClientValidation\Filament\ClientValidatedField;

ClientValidatedField::make('email')
    ->clientValidation('required|email')
    ->clientValidationMode('live');
```

---

Usage with Vanilla JS (No Framework)
------------------------------------

[](#usage-with-vanilla-js-no-framework)

### Using Data Attributes

[](#using-data-attributes)

```

    Submit

```

### Programmatic Validation

[](#programmatic-validation)

```
import { LaravelValidator } from 'laravel-client-validation/core';

const validator = new LaravelValidator({
    rules: {
        email: 'required|email',
        password: 'required|min:8'
    },
    messages: {
        'email.required': 'Email is required'
    }
});

const result = await validator.validateField('email', 'test@example.com');
console.log(result.valid, result.errors);

const formResult = await validator.validateAll({
    email: 'test@example.com',
    password: '12345678'
});
```

### Using Blade Directives

[](#using-blade-directives)

```

     'blur'])>

```

---

Using with FormRequest
----------------------

[](#using-with-formrequest)

### In Controller

[](#in-controller)

```
use MrPunyapal\ClientValidation\Facades\ClientValidation;

public function create()
{
    $validation = ClientValidation::fromRequest(CreateUserRequest::class);
    return view('users.create', compact('validation'));
}
```

### In Blade

[](#in-blade)

```

    {{-- Form fields --}}

```

---

Backend-Agnostic Remote Validation
----------------------------------

[](#backend-agnostic-remote-validation)

The `RemoteValidator` works with any backend, not just Laravel. Configure it for your stack:

### Express.js / Node

[](#expressjs--node)

```
import { RemoteValidator } from 'laravel-client-validation/core';

const remote = new RemoteValidator({
    endpoint: '/api/validate',
    csrf: false,
    requestFormatter: (field, value, rule, params) => ({
        field_name: field,
        field_value: value,
        validation_rule: rule,
        rule_params: params
    }),
    responseParser: (response) => ({
        valid: response.success,
        message: response.error || null
    })
});
```

### Django

[](#django)

```
const remote = new RemoteValidator({
    endpoint: '/validate/',
    csrfHeaderName: 'X-CSRFToken',
    csrfTokenResolver: () => document.cookie.match(/csrftoken=([^;]+)/)?.[1]
});
```

### Custom Adapter

[](#custom-adapter)

```
const remote = new RemoteValidator();
remote.setAdapter(async (field, value, rule, params) => {
    const res = await myHttpClient.post('/validate', { field, value, rule });
    return { valid: res.ok, message: res.error };
});
```
