Socket.io

[sistematico]

Anyway to use Hono with Socket.io, WebSockets or Bun builtin WebSockets?

Thank you in advance.

I believe you can create something like this (haven't test yet):

import { serve } from '@hono/node-server'
import { Hono } from 'hono'
import { WebSocketServer } from 'ws'

const app = new Hono()
const server = serve(app)

const ws = new WebSocketServer({ server })

ws.on('connection', (socket) => {
    socket.on('error', console.error)
    socket.on('message', (data) => console.log('message:', data))

    socket.send('something')
})

Sorry, i don't get the point:

import { Hono } from "hono";
import { serve } from "@hono/node-server";
import type { Server as HttpServer } from "node:http";
import { Server as SocketIOServer } from "socket.io";

const app = new Hono();
const server = serve({ fetch: app.fetch, port: 4001 });
const io = new SocketIOServer(server as HttpServer);

app.get("/", (c) => c.text("Hello Hono!"));

io.on("connection", (socket) => {
  socket.emit("hello", "world");
  socket.on("hello", (data) => {
    socket.broadcast.emit("hello", data);
  });
});

serve({ fetch: app.fetch, port: 4001 });

export { app };

Response from /: Welcome to Bun! To get started, return a Response object.

You're calling serve twice
