How to use WebSockets - JavaScript Tutorial For Beginners
In today's video I'll be taking you through the basics of creating a WebSockets application - we'll be covering the client side and the server side to send messages between the two.
WebSockets allow for two-way, event-driven communication between the web browser and a back-end WebSockets server.

I have to say I've watched a couple videos as I try to teach myself WS, most of them trying to assemble a chat app. Your tutorial is so clear and to the point that I didn't even need the whole chat app dressing and could figure it out on my own. Thanks for explaining the actual point so well. Earned subscribe.
Love the way you explained 25 pages of theory with a simple example. Direct to the point and no beating around the bush. Thanks a lot for the simple and crisp tutorial.

Wow! The best tutorial on WebSockets for beginners ever. Thanks.
Thanks for the coding tutorial and thanks for showing in the inspect network tab, showing the message sent/received. That was really important to me as well.
What an amazing channel! Found you 3 videos back, totally love your videos! Thank you!
loved the simplicity and to-the-point approach of explanation. Great Work
Very well explained with conciseness and clarity. Also, thank you very much for the reference link. Much appreciated. !!

Fantastic video, mate! Simple, and to the point.
This was.... so beautiful. You don't know how many resources I went through trying to get a basic understanding of websockets. So much BS theory. Thank you.
This is an amazing introduction video! No time wasted.

how can i disconnect another connected user? I am tryig to create a 'kick' function so i can disconnect pests from my server. I have a chatroom where some people need to be removed. I can not find anything on making commands like these. thanks
Very good tutorial for beginners.

Great and simple intro.
Best of the best man , Thank you so much
amazing video thank you so much!
Fantastic tutorial!
Very cool video :) thx 🙏🏼
I get a Blob as data. Any idea why?
If, in the terminal, you're getting the "Hey, how's it going?" message back as a string buffer instead of the actual sentence, you need to decode it before logging it out, using the string decoder module. At the top of index.js: ------------------ const { StringDecoder } = require('string_decoder'); const decoder = new StringDecoder('utf8'); ----------------- And, in the connection event: ----------------- ws.on('message', data => { console.log('client has sent us', decoder.write(data)) }) ----------------- That makes the message in the terminal appear decoded to a string.

Best explaination ever :)
This is great but on the NodeJS backend you'll have to convert your data to a string before trying to turn it uppercase. It's coming over for me as a buffer type, not a string, and the `toString()` method is unavailable. Not sure why it's working for him without that type conversion.

You are sooooo good explaining !! Can you do this same thing but with multiple clients connecting and the server distinguishing the different clients? Like a tic tac toe game or something similar?

Can you do a video tutorial on Vanilla Javascript on how to write a websocket and server. I can't use Node JS or AJAX or any other downloadable other langauges at my workplace. Please provide a pure Vanilla Javascript tutorial. Thank you so much if you can.
I see that if the server stops and restart, the connection disconnects and the page never tries to put that connection up again. How can I achieve that?
Maybe you could make a video about websockets without any external modules, it took me almost a month because the only guide that can be found is a documentation that explains how it works. By making a video about it i'm pretty sure you could get a much bigger channel because i've seen how many people are trying to do this but can't

Hi! I'm running into an issue regarding the ${data} part. When it logs 'Client has sent us ${data}' to the console, the message 'Hey how's it going does not appear, but the letters '${data}' themselves get logged. I'm new to js development and I'm at a loss for how to solve this. Do you have any suggestions? Thanks!

Unfortunately this depends on the service provider - you'd need to check your provider and see if they support Node.js and WebSocket connections

idk why but when i try this example code the "data" on server is type object so i ran into an error when i execute data.toUpperCase() i have to convert it to a string fist whit String(data) and then i can run the "toUpperCase" Method on it . can someone explain this to me ?
@heartbeathero

If toUpperCase isn't working then the following should explain why. In version 8 of ws text messages are no longer decoded to "string" but are passed as "Buffer". If you down grade to version 7.3.0 of ws then toUpperCase will work. But its beter to use version 8 of ws and convert the Buffer into a string before you try changing it to upper case. // ws.send(data.toUpperCase()); ws.send(String(data).toUpperCase()); More info here: stackoverflow.com/questions/69485407/why-is-received-websocket-data-coming-out-as-a-buffer More info here in the release of 8.0.0 github.com/websockets/ws/releases/tag/8.0.0
