from py_node_manager import NodeManager

# Create NodeManager instance
# download_node=True means automatically download Node.js if not found in system
# node_version specifies the Node.js version to download
manager = NodeManager(download_node=True, node_version='18.17.0')

# Get paths to Node.js, npm, and npx
node_path = manager.node_path  # Path to downloaded Node.js, None if using system Node.js
npm_path = manager.npm_path    # Path to npm
npx_path = manager.npx_path    # Path to npx

# Get environment variables (if using downloaded Node.js)
node_env = manager.node_env    # Environment variables dictionary

import subprocess
from py_node_manager import NodeManager

manager = NodeManager(download_node=True, node_version='18.17.0')

# Run Node.js commands
result = subprocess.run(
    [manager.npm_path, 'init', '-y'],
    env=manager.node_env,
    capture_output=True,
    text=True
)
print(result.stdout)
