Utilities for building applications.
Contains:
- Config loading from environment
- Bootstrap for logging
- Base class for creating async workers
- Async timeout decorator, which is very useful for writing async tests
Examples:
Env config
import os
from datek_app_utils.env_config.base import BaseConfig
os.environ["COLOR"] = "RED"
os.environ["TEMPERATURE"] = "50"
class Config(BaseConfig):
COLOR: str
TEMPERATURE: int
assert Config.COLOR == "RED"
assert Config.TEMPERATURE == 50The Config class casts the values automatically.
Moreover, you can test whether all the mandatory variables have been set or not.
import os
from datek_app_utils.env_config.base import BaseConfig
from datek_app_utils.env_config.utils import validate_config
from datek_app_utils.env_config.errors import ValidationError
os.environ["COLOR"] = "RED"
class Config(BaseConfig):
COLOR: str
TEMPERATURE: int
AMOUNT: int = None
try:
validate_config(Config)
except ValidationError as error:
for attribute_error in error.errors:
print(attribute_error)Output:
TEMPERATURE: Not set. Required type: <class 'int'>
Async timeout decorator
from asyncio import sleep, run
from datek_app_utils.async_utils import async_timeout
@async_timeout(0.1)
async def sleep_one_sec():
await sleep(1)
run(sleep_one_sec())Output:
TimeoutError
