README

A simple package to integrate Cap.js, an hCaptcha-like open source challenge, into your Laravel application.

This package provides a simple way to integrate Cap.js into your Laravel application.

Installation

You can install the package via composer:

composer require ashraam/laravel-capjs

Configuration

First, you need to publish the configuration file:

php artisan vendor:publish --provider="Ashraam\\Capjs\\CapjsServiceProvider" --tag="config"

This will create a config/capjs.php file in your application. You can then add your Cap.js credentials to your .env file:

CAPJS_HOST=
CAPJS_KEY=
CAPJS_SECRET=

Usage

Blade Directive

To include the Cap.js script, you can use the @capjsScript directive in your Blade template:

<!DOCTYPE html>
<html>
<head>
    ...
    @capjsScript
</head>
<body>
    ...
</body>
</html>

Facade

You can also get the script tag from the Capjs facade:

{!! Capjs::script() !!}

Blade Component

To display the Cap.js widget, you can use the <x-capjs-widget> component:

<form method="POST" action="/register">
    @csrf
    ...
    <x-capjs-widget />
    @error('cap-token') {{ $message }} @enderror
    ...
    <button type="submit">Register</button>
</form>

The component also accepts an optional id and locale attribute:

<x-capjs-widget id="my-capjs-widget" locale="fr" />

Events

The component dispatches custom events such as solve, error, reset, and progress. You can attach an event listener to the widget to capture these events.

For instance, to get the token when the captcha is solved, you would use the following JavaScript code:

const widget = document.querySelector("#my-capjs-widget");
widget.addEventListener("solve", function (e) {
  const token = e.detail.token; // Handle the token as needed
});

Styling

You can customize the appearance of the widget by overriding the default CSS variables.

cap-widget {
  --cap-background: #fdfdfd;
  --cap-border-color: #dddddd8f;
  --cap-border-radius: 14px;
  --cap-widget-height: 30px;

  --cap-credits-font-size: 12px;
  --cap-opacity-hover: 0.8;
}

Validation Rule

To validate the Cap.js token, you can use the capjs validation rule:

use Illuminate\Http\Request;

public function register(Request $request)
{
    $request->validate([
        ...
        'cap-token' => ['required', 'capjs'],
        ...
    ]);

    ...
}
