Use WebSockets

Echo server

import { tyoi } from "@donneko/tyoi-server";

const app = tyoi({
    root: import.meta.dirname,
    public: "../public/main",
});

app.ws("/ws", ({ ws, req }) => {
    console.log("connected", req.socket.remoteAddress);
    ws.send("connected");

    ws.on("message", (value) => {
        ws.send(`echo: ${value.toString()}`);
    });
});

await app.start();

Connect from a browser:

const socket = new WebSocket("ws://localhost:3000/ws");

socket.addEventListener("open", () => socket.send("hello"));
socket.addEventListener("message", (event) => console.log(event.data));

api is not added to WebSocket paths. WebSockets use the same HTTP server and port, and only connections whose URL pathname exactly matches a registered path are accepted.

Send to multiple clients

Keep connected ws instances in your application to implement chat or live notifications. The realtime-ts template includes an example.

tyoi create realtime-app --template realtime-ts

When the server stops, connected clients receive close code 1001.
