console.log(event.data);
socket.send('Hello, WebSocket! [Server]');
};
});
router.get('/', (context) => {
context.response.body = `
<h1>Hello, Oak!</h1>
<script>
const ws = new WebSocket('ws://localhost:8000/wss');
ws.onopen = () => {
console.log('WebSocket connection established!');
ws.send('Hello, WebSocket!');
};
ws.onmessage = (event) => {
console.log(event.data);
};
</script>
`;
context.response.type = 'text/html';
});
const app = new Application();
app.use(router.routes());
app.use(router.allowedMethods());
