# AMQP Kø 

Object oriented AMQP layer for microservices communication.

## Usage

The recommended way to use AMQP Kø is to create your own queue object. The simplest way to do this is using `createQueue` function.

### Create queue

```python

from amqp_ko import create_queue, AsyncConnection, Message, MessageGate

from dataclasses import dataclass

@dataclass(frozen=True)

class TopicFollow(Message):

    user_id: int

    topic_name: str

def unmarshal_topic_follow(data: dict) -> TopicFollow:

    return TopicFollow(

        user_id=data["user_id"],

        topic_name=data["topic_name"],

    )

message_gates = [

    MessageGate("topic_follow", TopicFollow, unmarshal_topic_follow),

]

async with AsyncConnection("localhost", 5672, "rabbitmq", "rabbitmq") as connection:

    queue = await create_queue(connection, "exchange-name", message_gates)

```

### Consume messages

```python

from amqp_ko import Consumer, Job

class ConnectUserWithTopic(Consumer):

    async def consume(self, job: Job[TopicFollow]):

        # Put here some code to connect user with a topic

        # using "job.message.user_id" and "job.message.topic_name"

        await job.ack()

        

await queue.consume(

    "queue-name",

    {TopicFollow: ConnectUserWithTopic()},

)

```

### Produce message

```python

message = TopicFollow(120, "entertainment")

await queue.produce(message)

```

## Installation

```bash

pip install amqp-ko

```
