A CLI tool that automatically generates Entity-Relationship Diagrams (ERD) for Laravel applications using model analysis.

---

📦 Installation

npm install @priom7/laravel2erd

Or use it directly with npx:

🚀 Features

• 📊 Automatically analyze Laravel models to generate ERDs
• 🔍 Detect table names, attributes, and data types
• 🔄 Map relationships (One-to-One, One-to-Many, Many-to-Many)
• 🖼️ Interactive web-based diagram viewer with zoom controls
• 💾 Export diagrams as SVG for documentation

---

🖥️ Usage

Basic usage

npx laravel2erd

Custom options

npx laravel2erd \
  --output public/docs/erd \
  --models app/Models \
  --title "My Project ERD"

Once generated, you can view your ERD diagram in the browser at:

http://your-app-url/laravel2erd

---

⚙️ Options

Option	Description	Default
-o, --output	Output directory for ERD	public/laravel2erd
-m, --models	Directory containing Laravel models	app/Models
-r, --relations	Include relationships between models	true
-t, --title	Title of the diagram	Laravel ERD Diagram

---

🧠 How It Works

Laravel2ERD performs static analysis on your Laravel model files to extract:

1. Table structure: Names, columns, and types
2. Attributes: From fillable arrays and casts
3. Relationships: Using Eloquent methods like hasOne, belongsTo, etc.

It then compiles this information into a clean Mermaid.js diagram rendered in a browser interface.

📋 Example Model

// app/Models/User.php
class User extends Model
{
    protected $fillable = [
        'name', 'email', 'password',
    ];
    
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];
    
    public function posts()
    {
        return $this->hasMany(Post::class);
    }
}

🧩 This model will be visualized with all attributes and relationships in the ERD diagram.
