Great news! Now Propan can be used as a full part of FastAPI!

from fastapi import FastAPI
from propan.fastapi import RabbitRouter

app = FastAPI()

router = RabbitRouter("amqp://guest:guest@localhost:5672")

@router.event("test")
async def hello(m: dict) -> dict:
     return { "response": "Hello Propan!" }

app.include_router(router)

You can find a complete example in documentation

Also, added the ability to test your application without running external dependencies as a broker (for now only for RabbitMQ)!

from propan import RabbitBroker
from propan.test import TestRabbitBroker

broker = RabbitBroker()

@broker.handler("ping")
async def healthcheck(msg: str) -> str:
     return "pong"

def test_publish():
     async with TestRabbitBroker(broker) as test_broker:
         await test_broker.start()
         r = await test_broker.publish("ping", queue="ping", callback=True)
     assert r == "pong"

Also added support for RPC over MQ (RabbitMQ only for now): return of your handler function will be sent in response to a message if a response is expected.

Breaking changes:

• Brokers publish_message method has been renamed to publish
• removed declare argument in RabbitQueue and RabbitExchange - now you need to use passive
