Bun
Manually integrate crossws with Bun.
You can use
serve function from crossws/server to automatically integrate crossws with Bun!To manually integrate crossws with your Bun server, you need to handle upgrade with handleUpgrade util and also pass the websocket object returned from the adapter to server options. crossws leverages native bun WebSocket API.
import crossws from "crossws/adapters/bun";
const ws = crossws({
hooks: {
message: console.log,
},
});
Bun.serve({
port: 3000,
websocket: ws.websocket,
fetch(request, server) {
if (request.headers.get("upgrade") === "websocket") {
return ws.handleUpgrade(request, server);
}
return new Response(
`<script>new WebSocket("ws://localhost:3000").addEventListener('open', (e) => e.target.send("Hello from client!"));</script>`,
{ headers: { "content-type": "text/html" } },
);
},
});
