📦 Installation

# Install using pip
pip install shapi

# Or install from source
git clone https://github.com/wronai/shapi.git
cd shapi
pip install -e .

🚀 Quick Start

Serve a Script

# Serve a script directly
shapi serve ./examples/echo.sh --port 8000

# Or run it as a daemon
shapi serve ./examples/echo.sh --name echo-service --port 8000 --daemon

# List running services
shapi service list

Manage Services

# List all running services
shapi service list

# Stop a service
shapi service stop service-name

# Restart a service
shapi service restart service-name

# Force stop if port is in use
shapi serve ./script.sh --port 8000 --force

Generate Service Structure

# Generate complete service structure with Docker and tests
shapi generate /path/to/your/script.sh --name my-service

# Navigate to the generated service
cd my-service

# Install dependencies and run
pip install -r requirements.txt
python main.py

• Development Guide - How to contribute to ShAPI

🔍 Examples

ShAPI comes with several example scripts that demonstrate its capabilities:

• ls.sh - List directory contents
• ps.sh - Show running processes
• df.sh - Display disk usage
• free.sh - Show memory usage
• whoami.sh - Display current user information
• date.sh - Show current date/time with formatting
• echo.sh - Echo back input text

See the examples documentation for detailed usage and API examples.

Usage Examples

Basic Script Conversion

#!/bin/bash
# hello.sh
echo "Hello, $1!"

Generate the service:

shapi generate hello.sh --name greeting-service
cd greeting-service
python main.py

Access your API:

• Health Check: GET http://localhost:8000/health
• Documentation: GET http://localhost:8000/docs
• Execute Script: POST http://localhost:8000/run

API Endpoints

Every generated service includes:

• GET /health - Service health check
• GET /info - Script information
• POST /run - Execute script (sync/async)
• GET /status/{task_id} - Check async task status
• GET /docs - Interactive API documentation

Service Management

Managing Multiple Services

# Start multiple services on different ports
shapi serve ./service1.sh --name service1 --port 8000 --daemon
shapi serve ./service2.sh --name service2 --port 8001 --daemon

# List all running services
shapi service list

# Output:
# ┏━━━━━━━━━━━┳━━━━━━━━┳━━━━━━┳━━━━━━━━━┳━━━━━━━━━━┳━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓
# ┃ Name      ┃ PID    ┃ Port ┃ Status  ┃ Uptime   ┃ Script                          ┃
# ┡━━━━━━━━━━━╇━━━━━━━━╇━━━━━━╇━━━━━━━━━╇━━━━━━━━━━╇━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┩
# │ service1  │ 12345  │ 8000 │ running │ 00:05:32 │ /path/to/service1.sh            │
# │ service2  │ 12346  │ 8001 │ running │ 00:02:15 │ /path/to/service2.sh            │
# └───────────┴────────┴──────┴─────────┴──────────┴─────────────────────────────────┘

# Stop a service
shapi service stop service1

# Force stop a service if it's not responding
shapi service stop service2 --force

# Restart a service
shapi service restart service1

Port Management

# Start a service with automatic port conflict resolution
shapi serve ./service.sh --port 8000 --force

# The --force flag will automatically stop any service using port 8000

Example API Request

POST /run
{
  "parameters": {
    "name": "World",
    "verbose": true
  },
  "async_execution": false
}

Docker Deployment

# Build and run with Docker
make docker-build
make docker-run

# Or use docker-compose
docker-compose up -d

Testing

# Run tests
make test

# Or directly
python -m pytest test_service.py -v

Configuration

Create a config.yaml file for advanced configuration:

service:
  name: "my-advanced-service"
  description: "Advanced shell script API"
  version: "1.0.0"
  
protocols:
  rest: true
  grpc: true
  webrtc: true
  
security:
  auth_required: false
  cors_enabled: true
  
monitoring:
  health_check_interval: 30
  metrics_enabled: true

CLI Commands

# Generate service structure
shapi generate hello.sh --name service-name --output ./output

# Serve script directly
shapi serve hello.sh --host 0.0.0.0 --port 8008

# Test generated service
shapi test ./generated/service-name

# Build Docker image
shapi build ./generated/service-name

Advanced Features

Async Execution

# Enable async execution for long-running scripts
response = requests.post("/run", json={
    "parameters": {"input": "data"},
    "async_execution": True
})

task_id = response.json()["task_id"]

# Check status
status = requests.get(f"/status/{task_id}")

Multiple Protocols

The generated service supports multiple communication protocols:

• REST API: Standard HTTP endpoints
• WebRTC: Real-time data streaming
• gRPC: High-performance RPC calls

Production Deployment

# Using Makefile
make deploy

# Manual deployment
docker-compose up -d

Requirements

• Python 3.8+
• Docker (optional, for containerization)
• Bash (for shell script execution)
