Laravel ReverseKit: Generate Your Entire Laravel Backend From a JSON Structure

Source: Dev.to

I just released a new Laravel package called Laravel ReverseKit that helps you build an entire Laravel backend from a single JSON structure — no AI required.

Instead of writing models, controllers, migrations, policies, tests, and resources manually, you define the output (JSON) once, and ReverseKit generates the full backend for you.

🚀 What Laravel ReverseKit Does

Laravel ReverseKit takes a JSON structure and generates:

• Models with $fillable, $casts, and relationships
• Migrations with inferred column types
• API Controllers with CRUD methods
• API Resources mirroring your JSON output
• Form Requests for validation
• Policies with ownership checks
• Model Factories and Seeders
• Feature Tests for your endpoints
• API routes registered via Route::apiResource()

🔧 How It Works

Create a JSON file describing your expected API response (or provide a JSON string) and run:

php artisan reverse:generate path/to/your.json

Additional sources you can use:

• Live API URLs (--from-url)
• OpenAPI/Swagger specs (--from-openapi)
• Postman collections (--from-postman)
• Existing database tables (--from-database)
• Interactive CLI mode (reverse:interactive)

The command generates all backend files based on the JSON structure you define — models, controllers, migrations, policies, and more.

📦 Quick Example

Input JSON

{
  "user": {
    "id": 1,
    "name": "John Doe",
    "email": "john@test.com",
    "posts": [
      { "id": 1, "title": "First Post", "body": "Content", "published": true }
    ]
  }
}

🛠 Why This Helps

Writing all the boilerplate for a new backend — models, migrations, relationships, policies, tests — takes a lot of time and repetitive typing. ReverseKit lets you focus on your domain logic and lets the tool scaffold the rest based on the output you care about.
