Simple and type-safe environment variables management for Python

easy-dotenv

Simple and type-safe environment variables management for Python.

Installation

pip install easy-dotenv

Usage

Create an environment configuration file (e.g., env_loader.py):

from easy_dotenv import EnvConfig

class Env(EnvConfig):
    port: int
    api_key: str
    debug: bool = False  # Optional with default value
    workers: int = 4     # Optional with default value

env = Env()

__all__ = ['env']

Then use it in your code:

from env_loader import env

print(f"Port: {env.port}")
print(f"API Key: {env.api_key}")
print(f"Debug mode: {env.debug}")    # False if not set
print(f"Workers: {env.workers}")     # 4 if not set

Features

• Type validation
• Required/optional variables
• Default values
• .env file support
• Clean and simple API
• Full type hints support
• No code duplication

Error Handling

The environment validation happens when you initialize the configuration:

from easy_dotenv import EnvConfig, EnvMissingError, EnvTypeError

try:
    class Env(EnvConfig):
        api_key: str
        port: int
    
    env = Env()
except EnvMissingError as e:
    print("Missing environment variables:", e)
except EnvTypeError as e:
    print("Invalid environment variable type:", e)
