Repid is a simple, fast, and extensible async task queue framework, with built-in AsyncAPI 3.0 schema generation.

pip install repid

• AsyncAPI 3.0 out of the box - your schema is generated automatically as you build. No separate spec files to maintain, no drift between code and docs.

• Broker flexibility - works with RabbitMQ, Redis, and Google Cloud Pub/Sub. Switch or run multiple brokers side by side without changing your actor code.

• FastAPI-style ergonomics - define actors as plain async functions with dependency injection and Pydantic argument validation. If you know FastAPI, you already know Repid.

• Built for testability - a drop-in TestClient lets you test actors in-memory without a running broker, making unit tests fast and dependency-free.

Here is how the simplest producer-consumer application looks, using AMQP server.

Producer:

import asyncio

from repid import AmqpServer, Repid

app = Repid(title="My App", version="1.0.0")
app.servers.register_server(
    "default",
    AmqpServer("amqp://user:password@localhost:5672"),
    is_default=True,
)


async def main() -> None:
    async with app.servers.default.connection():
        await app.send_message(
            channel="default",
            payload=b"",
            headers={"topic": "awesome_job"},
        )


asyncio.run(main())

Consumer:

import asyncio

from repid import AmqpServer, Repid, Router

app = Repid(title="My App", version="1.0.0")
app.servers.register_server(
    "default",
    AmqpServer("amqp://user:password@localhost:5672"),
    is_default=True,
)

router = Router()


@router.actor
async def awesome_job() -> None:
    print("Hello async jobs!")
    await asyncio.sleep(1.0)


app.include_router(router)


async def main() -> None:
    async with app.servers.default.connection():
        await app.run_worker()


asyncio.run(main())
