Brokkoly is a framework for enqueuing messages via HTTP request for celery.
CHANGELOG

Example

tasks.py:
import brokkoly

b = brokkoly.Brokkoly('example', 'redis://localhost:6379/0')
celery = b.celery

def two_times(text: str) -> dict:
return {
'text': text * 2
}

@b.task(two_times)
def echo(text: str) -> None:
print(text)
two_times works as pre processor. It works before enqueing. It means it can return BadRequest to your client. Brokkoly validate message with typehint. Also you can have extra validation and any other process here.
Run celery -A tasks worker --loglevel=info

producer.py:
import brokkoly

import tasks # NOQA

application = brokkoly.producer()
producer is WSGI application. You need to import your tasks for put message into queue.
Run with uWSGI uwsgi --http :8080 --wsgi-file producer.py --enable-threads --thunder-lock --master

Send Test Message!
curl -X POST -d '{"message":{"text": "Hello"}}' http://localhost:8080/example/echo

producer receives your request
producer validates your message having text and the type is str or not. text`(str) is from typehint of two_times
producer validates two_times returned value having text and the type is str or not. text`(str) is from typehint of echo
producer put message {"message":{"text":"HelloHello"}} into queue.
curl receives response.
Celery calls echo

Extra
preprocessor is optional. if you don’t need it, you can:
@b.task()
def echo(text: str) -> None:
print(text)
Also you can give multiple preprocessor:
@b.task(two_times, two_times)
def echo(text: str) -> None:
print(text)
