Adapters
Deno
Integrate CrossWS with Deno.
To integrate CrossWS with your Deno server, you need to check for the upgrade header and then call handleUpgrade method from the adapter passing the incoming request object. The returned value is the server upgrade response.
import wsAdapter from "crossws/adapters/deno";
const ws = wsAdapter({
hooks: {
message: console.log,
},
});
Deno.serve({ port: 3000 }, (request, info) => {
if (request.headers.get("upgrade") === "websocket") {
return ws.handleUpgrade(request, info);
}
return new Response(
`<script>new WebSocket("ws://localhost:3000").addEventListener("open", (e) => e.target.send("Hello from client!"));</script>`,
{ headers: { "content-type": "text/html" } },
);
});
Adapter Hooks
