Utilities for building applications.

Contains:

• Logging
• Loading config from environment variables

Config usage:

import os

from datek_app_utils.env_config import BaseConfig

os.environ["COLOR"] = "RED"
os.environ["TEMPERATURE"] = "50"


class Config(BaseConfig):
    COLOR: str
    TEMPERATURE: int


assert Config.COLOR == "RED"
assert Config.TEMPERATURE == 50

The values are being casted if you read them. Moreover, you can test whether all of the variables have been set or not.

import os

from datek_app_utils.env_config import BaseConfig, validate_config

os.environ["COLOR"] = "RED"


class Config(BaseConfig):
    COLOR: str
    TEMPERATURE: int


assert not validate_config(Config)

outputs:
