easy-dotenv 0.1.4

Easy environment variables management with type validation

easy-dotenv

Simple and type-safe environment variables management for Python.

Installation

pip install easy-dotenv

Usage

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

from easy_dotenv import EnvLoader

# Initialize environment variables once
env = EnvLoader.load(
    port=int,
    api_key=str,
    debug=(bool, False),  # Optional with default value
    workers=(int, 4)      # Optional with default value
)

__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
• Type hints support

Error Handling

The environment validation happens when you initialize the configuration:

from easy_dotenv import EnvLoader, EnvMissingError, EnvTypeError

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