Quick Start

Installation

pip install buunstack

Basic Usage

from buunstack import SecretStore

# Initialize with automatic token refresh (default)
secrets = SecretStore()

# Put API keys and configuration
secrets.put('api-keys', {
    'openai_key': 'sk-your-key-here',
    'github_token': 'ghp_your-token',
    'database_url': 'postgresql://user:pass@host:5432/db'
})

# Get secrets
api_keys = secrets.get('api-keys')
openai_key = api_keys['openai_key']

# List all your secrets
all_secrets = secrets.list()

Configuration Options

# Manual token management
secrets = SecretStore(auto_token_refresh=False)

# Custom refresh timing
secrets = SecretStore(
    auto_token_refresh=True,
    refresh_buffer_seconds=600,      # Refresh 10 minutes before expiry
    background_refresh_interval=3600 # Background refresh every hour
)

# Start background auto-refresh
refresher = secrets.start_background_refresh()

Environment Variables Helper

from buunstack import SecretStore, get_env_from_secrets, put_env_to_secrets

secrets = SecretStore()

# Put environment variables
project_env = {
    'PROJECT_NAME': 'ml-research',
    'MODEL_VERSION': 'v2.1',
    'DEBUG': 'false'
}
put_env_to_secrets(secrets, project_env)

# Get environment variables
loaded_vars = get_env_from_secrets(secrets)
# Now available as os.environ['PROJECT_NAME'], etc.
