How to connect to chat and send message

[cxzivxizeoqc]

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

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

Joining a chat room to recieve messages

• Joining a Twitch Chat Room | Twitch Developers

client.send(‘JOIN #somechannel’);

sending a message

• Sending and Receiving Chat Messages | Twitch Developers

client.send(‘PRIVMSG #somechannel :words to send’);

Should I just write like this?

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

I fix this error. instead of such quotes `` put such "

[cxzivxizeoqc]

like here:

connection.sendUTF('PASS oauth:yfvzjqb705z12hrhy1zkwa9xt7v662');
connection.sendUTF('NICK myusername');

?

[BarryCarlyon]

Sure but with the correct username an an oAuth token for it

[cxzivxizeoqc]

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');

should everything look like this?
But I have error…

[BarryCarlyon]

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

Nick are not preceeded with #

[cxzivxizeoqc]

I remove # from connection.sendUTF('NICK #s4tont');

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:

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');

@BarryCarlyon

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

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.
