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.

    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.

    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.

    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
