Description

Hi, I create a Fastify Websocket server following this tutorial. https://blog.logrocket.com/using-websockets-with-fastify/. However, although I get Connection established through the following code, I cannot succeed connecting to the WS through Postman, status remains connecting. https://postimg.cc/Wqh980p2

Steps to Reproduce

The source code is as follows.

const fastify = require('fastify')();
fastify.register(require('@fastify/websocket'));

fastify.get('/hello', (request, reply) => {
    reply.send({
        message: 'Hello Fastify'
    });
});
fastify.get('/hello-ws', { websocket: true }, (connection, req) => {
  console.log('Connection established');
  connection.socket.on('message', message => {
      connection.socket.send('Hello Fastify WebSockets');
  });
});

fastify.listen({ port: 3000 }, (err, address) => {
    if(err) {
        console.error(err);
        process.exit(1);
    }
    console.log(`Server listening at: ${address}`);
});

When I ping the server, I get

npm run start

> ws-test@1.0.0 start
> node main.js

Server listening at: http://[::1]:3000
Connection established

Expected Behavior

I expect to have a socket connected

Hi, Any idea on this? Any logs to look at to provide you additional information?

Either await fastify.register or wrap your route with plugin. Please read the document about the proper usage.
