Sincerely, you're born to teach. You have talent, you have taught me so many things and you explain them so nicely. Keep doing this, you're amazing af.

The purpose of WebSockets isn't to make persistent connections that allow multiple requests. That could be achieved in HTTP through "keep-alive". The purpose of WebSockets is to make bidirectional connexions, in which the server can initiate the interaction with the client, in opposition to HTTP where the client is always the one initiating the interaction and the server only responds to the requests.

[@upsxace]

Amazing and accurate comment!

Thank you for organizing everything about the socket! It's better quality than other paid lectures. Thank you very much!

[@seanfang398]

I really love Kyle's video style, always having so many concepts and infomation to be explained so clearly in such a few words, so briefly yet comprehensive

[@bobdinitto]

Kyle packs a lot of information into a small space. I sometimes have to watch the video multiple times to take it all in, but I'd much rather that than having to lumber through a long and tedious explanation. A few presenters have put me to sleep but Kyle never will.

[@miguelbuising6391]

this is so timely. Im currently creating a messaging app using react. thanks for this kyle!

[@br2716]

How do you always put out videos relevant to EXACTLY what I am looking for? Its scaring me Kyle!

[@breezycodes]

@2:51 is very important. For the longest while I always thought that the socket connection died after each event. Good job Kyle 👏🏽

[@yitzchaksviridyuk932]

Great tutorial. Really covers the foundations clearly and concisely. Thank you very much.

[@pattmehta5835]

Thank you, this is a very in depth tutorial on socketio and you did a very good work with the examples

[@jarodday1299]

My capstone class is finishing up a 7-week project where we learned all about server-side and database related frameworks, libraries, and other related syntax in Javascript. This tutorial is foundational to my completion of the project and I, as well as many others, owe it to you for your concise, sharp delivery in teaching. We thank you for being so instrumental in our learning journeys

[@seharnazeerseharnazeer973]

Detailed tutorial on web sockets . Highly recommended.

[@MA-nw3xf]

Really great explanation! The challenge I have now is how to make this scale horizontally. Let's say I have multiple instances of the server, one client is sending a message to serverA, then clients connected to serverB, and serverC should also be notified.

[@samuelvalentine7846]

I know you might not need this anymore, i am kind of having the same scenario, i think it it better to make all your user have a specific id maybe from the database that would make the id consistent, because the id that socketio assigns is not for development purpose but for debugging purpose, that is why it changes on every reconnection. What i have planned to do is to make the server emit to `friend-${user.id}` and the client listen to `friend-${user.id}`. I think, no matter the server, the id is always constant and the client only listens to a particular string or event that concerns it. I hope this helps. Please also share the way you solved the problem here so myself and others can learn too. Thanks a lot

May the Righteous and Holy force be with you Jedi Kyle. I definitely would like to implement this somewhere on my web space.

[@Stoney_Eagle]

I just created my ffmpeg progress dashboard with sockets using Node, React and Material-UI. It works like the youtube upload thingy. But there are no uploads in this situation so the calculations are accurate. I'm watching the fruits of my labor on my second screen as I watch this video. So close to the release of my NoMercy TV project.

It's like you're reading my god damn mind. I can't thank you enough I was about to watch a 3 hour tutorial that covers what you cover in a more explanatory way. Thank you so so so much!. I just noticed that you don't include a repository for the video or at least the boiler plate code It'd be nice if you could add that.

[@silentstone1]

Same here

[@MiSt3300]

incredilbe, same for me, I also just needed that tutorial so bad!

[@karuneshkaimal]

great tutorial , question from production deployment perspective will socket server will be an independent api gateway where the main app connects to ? If not what's the standard of deploying ?

[@nro337]

Thank you!

[@samuelerbo]

Super useful!!! Thanks a lot @WebDevSimplified!

[@elnndselman8869]

thank you for this brooo

[@siddharthmishra8233]

@11:08 instead of using broadcast we can just do one thing in the code of script.js we can just remove the line displaymessage(message) before the socket.emit ("send-message");

[@MukulJainx]

Great video, wanted to try Socket as I never got a chance to work on them professionally. Just a correction, I might wrong here. At around 17:00, I don't think the server actually called the callback but it told the client to call the callback along with sending the params, now params can be easily sent if serializable.

[@PatMacintosh]

From what I can tell, socket.join(), is a synchronous function according to the documentation. It seems right the way he explains it, but that’s just how I’m reading it. Need to play around with it to verify for sure.

[@sreejith5966]

Have been just working with socket io today

[@infinitetime3000]

Awesome video today

[@yapayzeka]

11:15 this way user can't be sure about connection. I would prefer incoming msg from server so I can be sure it's sent to everyone in channel including me. great presentation thank you.
