### API Blueprint Generator

Stop writing APIs twice. Write the spec once, get the working code.

-----

### 🚀 Quick Start

Transform this simple Markdown specification:

````markdown
# Todo API

## Data Models

### Todo
- id: integer (primary key)
- title: string (required)
- completed: boolean (default: false)
- created_at: datetime

## Endpoints

### GET /todos
**Description**: Get all todos
**Response**: 
- 200: `{"todos": [...]}`

### POST /todos
**Description**: Create a new todo
**Request Body**:
```json
{
  "title": "Buy groceries"
}
````

**Response**:

  - 201: `{"id": 1, "title": "Buy groceries", "completed": false}`

<!-- end list -->

````

Into a production-ready API in seconds:

```bash
pip install api-blueprint-generator
blueprint generate todo-spec.md --output todo-api
cd todo-api && docker-compose up
````

**Result**: A working Flask API with a database, validation, tests, and documentation available at `http://localhost:5000`.

-----

### 🎯 Why API Blueprint Generator?

**The Problem**

  - Writing API documentation, then implementing the same logic again.
  - Manually keeping documentation and code in sync.
  - Starting every API project from scratch.
  - Inconsistent patterns across team projects.

**The Solution**

  - **Single Source of Truth**: One Markdown file defines everything.
  - **Production Ready**: The generated code includes tests, validation, and deployment configuration.
  - **Time Savings**: A 70% reduction in API scaffolding time.
  - **Best Practices**: Follows established patterns for security, validation, and structure.

### 📋 Installation

**Using pip (Recommended)**

```bash
pip install api-blueprint-generator
```

**Using Docker**

```bash
docker pull blueprintgen/api-generator
docker run -v $(pwd):/workspace blueprintgen/api-generator generate spec.md
```

**From Source**

```bash
git clone https://github.com/yourusername/api-blueprint-generator.git
cd api-blueprint-generator
pip install -e .
```

-----

### 🔧 Usage

#### Basic Generation

```bash
# Generate API from a markdown spec
blueprint generate my-api-spec.md

# Specify the output directory
blueprint generate my-api-spec.md --output my-project

# Use a different backend
blueprint generate my-api-spec.md --backend fastapi

# Include PostgreSQL setup
blueprint generate my-api-spec.md --database postgresql
```

#### Configuration File

Create a `blueprint.yml` file for project defaults:

```yaml
backend: flask                   # flask, fastapi
database: postgresql             # sqlite, postgresql, mysql
auth_type: jwt                   # jwt, session, oauth, none
include_tests: true
docker_setup: true
api_prefix: "/api/v1"
cors_enabled: true
rate_limiting: true
```

#### Development Workflow

1.  **Generate your API**: `blueprint generate api-spec.md --output my-api`
2.  **Run locally**: `cd my-api && docker-compose up --build`
3.  **Regenerate**: `blueprint generate ../api-spec.md --output . --overwrite`
4.  **Run tests**: `python -m pytest tests/`
5.  **Deploy**: `docker build -t my-api .`

### 🔧 Customization

#### Adding Custom Business Logic
Generated routes include clear customization points:
```python
# app/routes/products.py (generated)
@products_bp.route('/', methods=['POST'])
@require_auth
@validate_json(CreateProductSchema)
def create_product():
    # Generated validation code
    data = request.get_json()
    
    # CUSTOMIZATION POINT: Add your business logic here
    # Example: Check inventory, send notifications, etc.
    
    # Generated persistence code
    product = Product(**data)
    db.session.add(product)
    db.session.commit()
    
    return jsonify(product.to_dict()), 201
````

#### Custom Templates

Override any generated file by creating a `templates` directory:

```bash
mkdir templates
cp ~/.api-blueprint/templates/routes.py.j2 templates/
# Edit templates/routes.py.j2 with your customizations
blueprint generate spec.md --template-dir templates
```

#### Middleware Customization

The `app/middleware.py` file is generated with customization points for authentication, logging, and more.

-----

### 🧪 Testing

Generated projects include comprehensive test suites:

```bash
# Run all tests
python -m pytest

# Run with coverage
python -m pytest --cov=app tests/

# Run a specific test file
python -m pytest tests/test_products.py

# Run integration tests only
python -m pytest tests/integration/
```

**Generated Test Types**:

  - **Unit Tests**: Model validation and business logic.
  - **Integration Tests**: Full API endpoint testing.
  - **Database Tests**: Migration and constraint validation.
  - **Authentication Tests**: Permission and token validation.
  - **Performance Tests**: Response time benchmarks.

-----
