Environment Variables

Basic Usage

from pydantic import BaseModel
from utilityhub_config import load_settings

class Config(BaseModel):
    database_url: str
    debug: bool = False

export DATABASE_URL=postgres://localhost/prod
export DEBUG=true

settings, _ = load_settings(Config)
print(settings.database_url)  # postgres://localhost/prod

settings, _ = load_settings(Config, env_prefix="MYAPP")

export MYAPP_DATABASE_URL=postgres://localhost/prod
export MYAPP_DEBUG=true

settings, _ = load_settings(Config, env_vars=False)

When env_vars=False, no environment variable lookup is performed at all, even if env_prefix is also provided.

Python field → Environment variable: - database_url → DATABASE_URL - max_workers → MAX_WORKERS - With prefix: MYAPP_DATABASE_URL
