WebSocket connector for Ypy

Project description

Build Status Code style: black

ypy-websocket

ypy-websocket is an async WebSocket connector for Ypy.

Usage

Client

Here is a code example:

import asyncio
from websockets import connect
from ypy_websocket import YDoc, WebsocketProvider

async def client():
    ydoc = YDoc()
    websocket = await connect("ws://localhost:1234/my-roomname")
    WebsocketProvider(ydoc, websocket)
    ymap = ydoc.get_map("map")
    with ydoc.begin_transaction() as t:
        ymap.set(t, "key", "value")

asyncio.run(client())

Note that YDoc has to be imported from ypy_websocket instead of y_py. This will change in the future, when y_py has the necessary event handlers. ypy_websocket.YDoc is a subclass of y_py.YDoc.

Server

Here is a code example:

import asyncio
from websockets import serve
from ypy_websocket import WebsocketServer

async def server():
    websocket_server = WebsocketServer()
    async with serve(websocket_server.serve, "localhost", 1234):
        await asyncio.Future()  # run forever

asyncio.run(server())

WebSocket API

The WebSocket object passed to WebsocketProvider and WebsocketServer.serve must respect the following API:

class WebSocket:

    @property
    def path(self) -> str:
        # can be e.g. the URL path
        # or a room identifier
        return "my-roomname"

    def __aiter__(self):
        return self

    async def __anext__(self) -> bytes:
        # async iterator for receiving messages
        # until the connection is closed
        try:
            message = await self.recv()
        except:
            raise StopAsyncIteration()
        return message

    async def send(self, message: bytes):
        # send message
        pass

    async def recv(self) -> bytes:
        # receive message
        return b""
