I connect to Twitch Chat via a socket, using an IRC style interface.  
My code:

```auto
const WebSocketClient = require('websocket').client;
const client = new WebSocketClient();

client.on('connectFailed', function(error) {
    console.log('Connect Error: ' + error.toString());
});

client.on('connect', function(connection) {
    console.log('WebSocket Client Connected');
    
    // Send CAP (optional), PASS, and NICK messages
});

client.connect('ws://irc-ws.chat.twitch.tv:80');

```

But how to send a message immediately after connecting? And how do you choose which channel to connect to?  
I just don’t know how to connect to the chat

Should I just write like this?

```auto
const WebSocketClient = require('websocket').client;
const client = new WebSocketClient();

client.on('connectFailed', function(error) {
    console.log('Connect Error: ' + error.toString());
});

client.on('connect', function(connection) {
    console.log('WebSocket Client Connected');
    
    // Send CAP (optional), PASS, and NICK messages
});

client.connect('ws://irc-ws.chat.twitch.tv:80');

client.send(‘JOIN S4tont’);
client.send(‘PRIVMSG S4tont :hello!’);

```

Channel names are all lowercase and preceeded by `#`

You also seem to lack the `PASS` and `NICK` commands to login to the server as documented

You cast the websocket to `client` then tried to use it under `connection`

Nick are not preceeded with `#`

Hello! I wrote the code, but I’m not sure if I wrote it correctly. I have to connect to the chat and immediately send a message.  
My code:

```auto
const WebSocketClient = require('websocket').client;
const client = new WebSocketClient();

client.on('connectFailed', function(error) {
    console.log('Connect Error: ' + error.toString());
});

client.on('connect', function(connection) {
    console.log('WebSocket Client Connected');
    connection.sendUTF('PASS oauth:vz9fcq1xv0qxxr7kcr2g9btubgdofayyzq2r142p7kygtqx12zde4ugpdx83tt1qr35u6jqlcbbn4ix526rgsfxiypq130z2kbqflvxyxf5jnl4j7ued2nyt17b9iayzcg959kxw2cp69q4e3mzkfmfwhtmy46601oy46z6uf6qus2y5qq9egoo1c8f7qvpwreen0gfdnb57o6xscqpdddfyfe62oykiniiu7zatq44imae3rjxr2un04r1ut2jd6j3tnt2oao19l7ro43j12nn1h1rmc71tvtxtm7qm324zbvpwn6g3i1rxyfnw4f0pero884hedm3ilxe6qa47lcb7ou01m47g4oknw1gizt9vwh7m8cowi5jdalf5t87vpb5e9v5kpw170iimnykjf8x4ao0icrf5y4dv');
    connection.sendUTF('NICK S4tont');
});

connection.on('message', function(ircMessage) {
  client.send('JOIN #s4tont');
  client.send('PRIVMSG #s4tont :hello!');
});

client.connect('ws://irc-ws.chat.twitch.tv:80');

```

Error:

```auto
/home/user/Documents/typescript/bots/twitch/twitch.js:42
connection.on('message', function(ircMessage) {
^

`conneciton` doesn’t exist, based on the presented code it appears it should be client.

You may wish to refer to a javascript primer before continuing trying to write javascript.
