aioudp 1.0.1

AioUDP

A better API for asynchronous UDP

A websockets-like API for UDP
Here's an example echo server:
import asyncio
import signal

import aioudp

async def main():
async def handler(connection):
async for message in connection:
await connection.send(message)

# Optional. This is for properly exiting the server when Ctrl-C is pressed
# or when the process is killed/terminated
loop = asyncio.get_running_loop()
stop = loop.create_future()
loop.add_signal_handler(signal.SIGTERM, stop.set_result, None)
loop.add_signal_handler(signal.SIGINT, stop.set_result, None)

# Serve the server
async with aioudp.serve("localhost", 9999, handler):
await stop # Serve forever

if __name__ == '__main__':
asyncio.run(main())

And a client to connect to the server:
import asyncio

import aioudp

async def main():
async with aioudp.connect("localhost", 9999) as connection:
await connection.send(b"Hello world!")
assert await connection.recv() == b"Hello world!"

if __name__ == '__main__':
asyncio.run(main())

Installation
You can get this project via pip
$ pip install aioudp

Or, if you're using Poetry
$ poetry add aioudp

[!NOTE]
This library provides no other abstractions over the existing UDP interface in asyncio other than the async/await-based API. This means there is no implicit protocol handled in this library such as QUIC. You must write your own, or find another library.
