SignalR core client (async fork)

This is asyncio version of the original SignalR Core library.
The main difference is that websocket library is replaced with asyncio-compatabile websockets.
All future changes in the original repo will be merged to this fork inheriting the major and minor version number.

Installation

pip install aiosignalrcore

Usage

Check out the docs of the original library.
The names of all modules, classes, and methods are preserved.

Async example

import asyncio
import logging
from aiosignalrcore.hub_connection_builder import HubConnectionBuilder
from aiosignalrcore.messages.completion_message import CompletionMessage
from aiosignalrcore.transport.websockets.connection import ConnectionState


hub_connection = (
    HubConnectionBuilder()
        .with_url('%URL%')
        .with_automatic_reconnect(
            {
                "type": "raw",
                "keep_alive_interval": 10,
                "reconnect_interval": 5,
                "max_attempts": 5,
            }
        )
        .build()
)


async def on_connect():
    logging.info('Connected to the server')
    
    while hub_connection.transport.state != ConnectionState.connected:
        await asyncio.sleep(0.1)

    await hub_connection.send("SendMessage", [])


async def on_message(message):
    pass


def on_error(self, message: CompletionMessage):
    raise Exception(message.error)


hub_connection.on_open(on_connect)
hub_connection.on_error(on_error)
hub_connection.on("Message", on_message)

await hub_connection.start()

try:
    while hub_connection.transport.state == ConnectionState.connected:
        await asyncio.sleep(1)
except KeyboardInterrupt:
    pass
finally:
    await hub_connection.stop()
