📦 Installation

pip install joy-config

🚀 Quick Start

Auto-loading Configuration

from joy_config.loader import auto_loader

# Automatically detect and load configuration files in your project
config = auto_loader()

# Access configuration items
db_host = config.database.host
# or
db_host = config['database.host']
# or with default value
db_host = config.get('database.host', 'localhost')

Specifying Configuration Files

from joy_config.loader import auto_loader

# Specify a configuration file path
config = auto_loader('config/app_config.yaml')

# Specify an environment
config = auto_loader(env='production')

📄 Supported Configuration Formats

YAML 📝

database:
  host: localhost
  port: 5432
  username: admin
  password: secret

app:
  debug: false
  log_level: info

JSON 📝

{
  "database": {
    "host": "localhost",
    "port": 5432,
    "username": "admin",
    "password": "secret"
  },
  "app": {
    "debug": false,
    "log_level": "info"
  }
}

INI 📝

[database]
host = localhost
port = 5432
username = admin
password = secret

[app]
debug = false
log_level = info

Environment Variables (.env) 📝

DATABASE_HOST=localhost 
DATABASE_PORT=5432 
DATABASE_USERNAME=admin 
DATABASE_PASSWORD=secret 
APP_DEBUG=false 
APP_LOG_LEVEL=info

🌐 Environment-Specific Configuration

joy-config supports loading different configuration files based on the current environment:

1. 🔍 Automatically detects the current environment from environment variables (ENV, ENVIRONMENT, or PROFILE)
2. 📁 Looks for environment-specific configuration files like config-dev.yaml, application-prod.json, etc.
3. 🔄 Intelligently merges base configuration with environment-specific overrides

Example:

# With environment variable ENV=dev
config = auto_loader()  # Will automatically load both config.yaml and config-dev.yaml

🔧 Advanced Usage

Configuration Merging 🔄

# Base config (config.yaml)
# database:
#   host: localhost
#   port: 5432
#   username: admin

# Environment config (config-prod.yaml)
# database:
#   host: db.example.com
#   password: prod-secret

# Merged configuration
# config.database.host == "db.example.com"
# config.database.port == 5432
# config.database.username == "admin"
# config.database.password == "prod-secret"

Converting to Dictionary 🔄

# Convert the configuration object to a dictionary
config_dict = config.as_dict()
