### Requirements

python 3.8+

### Installation

```bash
pip install aioworker
```

### Usage

```python
import asyncio

from aioworker import Service, Worker

async def task_1(loop):
    while True:
        print('Hello world')
        await asyncio.sleep(2)


if __name__ == '__main__':
    #  Run the server using 1 worker processes.
    Worker(tasks=[task_1]).run(workers=1)
```

or run tasks and the webserver

```python
import asyncio

from aioworker import Service, Worker


async def sleeping(loop):
    while True:
        print('Sleeping for 2 seconds...')
        await asyncio.sleep(2)


async def on_client_connect(reader, writer):
    """
    Read up tp 300 bytes of TCP. This could be parsed usign the HTTP protocol for example
    """
    data = await reader.read(300)
    print(f'TCP Server data received: {data} \n')
    writer.write(data)
    await writer.drain()
    writer.close()


if __name__ == '__main__':
    # Run the server using 1 worker processes.
    Worker(
        tasks=[sleeping],
        web_server_config={
            'client_connected_cb': on_client_connect,
        },
    )).run(workers=1)
```
