WebSockets support about vinxi HOT 9 CLOSED

I am working with the nitro team on this. We already enabled websocket support for the dev server using @vinxi/listhen, a temporary fork of listhen that enables websocket support until unjs/listhen#128 lands.

We will then try to land APIs for h3 and nitro that make it easy to write cross-platform websocket servers

from vinxi.

Now that the referenced PR is closed, is there any place to track the progress on WS support, h3/nitro API, etc.?

from vinxi.

So looks like unjs has introduced crossws package. This will be integrated in h3/nitro soon. I don't think there is a tracking issue, but we should get this soon. @pi0 i don't know if we have a timeline yet right

from vinxi.

I guess the important part that is missing, is the hook to listen for the upgrade event unjs/nitro#2041
Hopefully @pi0 will take a look at it soon.

released in 0.3.6

Thanks a lot! Is there a tracking issue for bringing this into start?

Its immediately available in start. Set server.experimental.websocket: true in config file.

You can then add a new router to your vinxi app, like this:

import { defineConfig } from "@solidjs/start/config";

const app = defineConfig({
  server: {
    experimental: {
      websocket: true,
    },
  },
});

app.addRouter({
  name: "websocket",
  type: "http",
  handler: "./src/websocket.ts",
  target: "server",
  base: "/_ws",
});

export default app;

src/websocket.ts

import { defineWebSocket, eventHandler } from "vinxi/http";

export default eventHandler({
	handler: () => {},
	websocket: defineWebSocket({
		async open(event) {
			console.log("WebSocket opened");
		},
		async message(peer, event) {
			console.log("WebSocket message", event);
			peer.send("YOOO");
		},
		async close(event) {
			console.log("WebSocket closed 3");
		},
	}),
});

To connect to the websocket try,

const ws = new WebSocket('ws://localhost:3000/_ws')

from vinxi.

Is there a way to import WSRequest, Peer, Message etc. types from vinxi?

defineWebSocket({
  upgrade: (req: WSRequest) => MaybePromise<void | { headers?: HeadersInit }>;
  message: (peer: Peer, message: Message) => MaybePromise<void>;
  open: (peer: Peer) => MaybePromise<void>;
  close: (peer: Peer, details: { code?: number; reason?: string }) => MaybePromise<void>;
  error: (peer: Peer, error: WSError) => MaybePromise<void>;
})

Maybe it should look something like this: solidjs/solid-start#1384
