README

A small Laravel package that leaves a friendly message for curious developers who peek at your source code or open DevTools.

What it does

Injects an HTML comment after <head> — visible in browser source view
Injects a styled console message before </body> — visible in DevTools → Console
Only activates in configured environments (default: production)
Skips JSON responses, redirects, and non-HTML content automatically
Zero configuration required — works out of the box via auto-discovery

Installation

composer require zhylon/open

That's it. The package registers itself via Laravel's auto-discovery.

Configuration

Publish the config file if you want to customize the messages:

php artisan vendor:publish --tag=zopen-config

This creates config/zopen.php:

return [
    'html_comment' => [
        'enabled' => env('ZHYLON_OPEN_HTML_COMMENT', true),
        'message' => env('ZHYLON_OPEN_HTML_MESSAGE', '👋 Hello curious developer! ...'),
        'github'  => env('ZHYLON_OPEN_GITHUB', 'https://github.com/Zhylon'),
        'website' => env('ZHYLON_OPEN_WEBSITE', 'https://zhylon.net'),
    ],

    'console' => [
        'enabled' => env('ZHYLON_OPEN_CONSOLE', true),
        'message' => env('ZHYLON_OPEN_CONSOLE_MESSAGE', 'Hey, you found us! 🚀'),
        'style'   => env('ZHYLON_OPEN_CONSOLE_STYLE', 'color: #6366f1; font-size: 14px; font-weight: bold;'),
    ],

    'environments' => ['production'],
];
