PyPI Changelog License

Easly integrate socket.io with your FastAPI app.

Installation

Install this plugin using pip:

$ pip install fastapi-socketio

Usage

To add SocketIO support to FastAPI all you need to do is import SocketManager and pass it FastAPI object.

# app.py
from fastapi import FastAPI
from fastapi_socketio import SocketManager

app = FastAPI()
socket_manager = SocketManager(app=app)

Now you can use SocketIO directly from your FastAPI app object.

# socket_handlers.py
from .app import app

@app.sio.on('join')
async def handle_join(sid, *args, **kwargs):
    await app.sio.emit('lobby', 'User joined')

Or you can import SocketManager object that exposes most of the SocketIO functionality.

# socket_handlers2.py
from .app import socket_manager as sm

@sm.on('leave')
async def handle_leave(sid, *args, **kwargs):
    await sm.emit('lobby', 'User left')
