• JSON-RPC over WebSockets support via aiohttp

Unimplemented JSON-RPC Features

• Batched requests
• Manifests

Examples

See the examples directory for more.

Quick server example

import asyncjsonrpc
from aiohttp import web

methods = asyncjsonrpc.MethodGroup()

@methods.method
def greet(name):
    return f'Hello {name}!'

rpcserver = asyncjsonrpc.server.AiohttpWebsocketServer(methods)
app = web.Application()
app.add_routes([web.get('/', rpcserver)])
web.run_app(app)

Quick client example

import asyncjsonrpc, asyncio
from aiohttp import web

async def main():
    client = asyncjsonrpc.client.AiohttpWebsocketClient()
    await client.connect('http://localhost:8080/')
    print(await client.greet('world'))

asyncio.run(main())
