Gemini Banner Generator for Laravel

A Laravel package to generate high-quality website advertisement banners using Google Gemini Image API, designed specifically for book stores and publishers.

This package strictly preserves original book cover text, typography, and layout by enforcing copy-paste image usage instead of AI text recreation.

✨ Features

• 🎨 AI-generated website banners using Google Gemini
• 🔒 Private input images, 🌍 public generated banners
• ❌ Zero text distortion or hallucination
• 📐 Aspect-ratio locking via reference image
• ⚡ Sync & Async (Queue) support
• 🧱 Clean service-based architecture
• 🪄 Facade for simple usage
• 🧪 Queue-safe & retry-safe
• ⚙️ Fully configurable storage paths & disks
• 📦 Laravel auto-discovery support

📦 Installation

Via Composer

composer require vedanshi-shethia/gemini-banner

⚙️ Configuration

Publish the config file:

php artisan vendor:publish --tag=gemini-banner

This creates:

config/gemini-banner.php

🔗 Storage Symlink (Required)

This package stores generated banners on the public disk. Make sure the public storage symlink exists:

php php artisan storage:link

This creates:

public/storage → storage/app/public

🔑 Environment variables

GEMINI_API_KEY=your_google_gemini_api_key

# Storage
GEMINI_INPUT_DISK=local
GEMINI_OUTPUT_DISK=public

🧠 Storage Design (Important)

This package follows industry best practices:

storage/
├── app/
│   ├── private/
│   │   └── gemini/input/
│   └── public/
│       └── gemini/output/

⚙️ Config Reference

return [

    'api_key' => env('GEMINI_API_KEY'),

    'endpoint' => 'https://generativelanguage.googleapis.com/v1beta/models/gemini-2.5-flash-image:generateContent',

    'disks' => [
        'input'  => env('GEMINI_INPUT_DISK', 'local'),
        'output' => env('GEMINI_OUTPUT_DISK', 'public'),
    ],

    'paths' => [
        'front'     => 'gemini/input/front',
        'back'      => 'gemini/input/back',
        'reference' => 'gemini/input/reference',
        'output'    => 'gemini/output',
    ],

    'cleanup' => [
        'enabled' => true,
    ],
];

🚀 Usage

1️⃣ Sync Generation (Facade)

use Vedanshi\GeminiBanner\Facades\GeminiBanner;
use Vedanshi\GeminiBanner\Http\Requests\GenerateBannerRequest;

function (GenerateBannerRequest $request) {
    $result = GeminiBanner::generate($request->payload());
}

Returns a public URL of the generated banner.

2️⃣ Async Generation (Queue)

use Vedanshi\GeminiBanner\Jobs\GenerateGeminiBannerJob;
use Vedanshi\GeminiBanner\Http\Requests\GenerateBannerRequest;

function (GenerateBannerRequest $request) {
    GenerateGeminiBannerJob::dispatch($request->payload());
}

✅ Ideal for:

• Heavy image processing
• High-traffic systems
• Background workflows

🧾 Expected Payload Structure

[
    'front_image' => string,        // path on input disk
    'back_image' => string,         // path on input disk
    'transparent_image' => string,  // path on input disk
    'product_name' => string,
]

⚠️ Do NOT pass temp paths (php/tmp). Files must be stored first using Laravel storage.

🧹 Automatic Cleanup

• Input images are deleted immediately after successful generation
• Cleanup is retry-safe
• Cleanup can be disabled via config

'cleanup' => [
    'enabled' => false,
],
