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.

Very nice video. Thanks a lot. But it would be really helpful if you add a link to the file in the description as well. Even if its not the finished code, at least the stater files so we can follow along. All the same thank you so much for this very informative video
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.
This comment means that you add "credentials: true" to the object cors when creating the variable io. I also faced an error "invalid namespace", in order to fix that you just have to remove the "/admin" part from the end of the server URL (so it is just localhost:3000)
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.
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.
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.
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.
Suggestion: As I have enjoyed your tutorials. You should try to slow down when you create tutorials on any topic, this might be holding your views back. Not everyone is that fluent in English.
Fantastic lesson. Noob question: I wish to implement a socket inside a Lambda that will be deployed to the cloud, how does the "port/server" work in this case?
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
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.
did you not share link to initial code? I'd like to follow along, but I don't feel like trying to figure out what you typed where before following along stated
What's the rule for when to use 'io' vs 'socket' on the server? I originally thought that 'socket' (specifically 'socket.on()') was used by both client and server to _handle_ an event but that when it came to _sending_ an event the client used 'socket.emit()' while the server used 'io.emit()'. That looks not to be the case, such as in the example of broadcasting where the server uses 'socket.broadcast.emit()'. So now I'm confused about when I should be using io/io.emit() on the server. And what about 'io.to()'? Is there a 'socket.to()' to be used on the server or would you just emit from the client with something like this... socket.emit('eventName', { receiver: '', msg: 'text' }); ...and then on the server run something like... socket.on('eventName', (data) => { io.to(data.receiverId).emit('otherEvent', data.msg); }); ...which is then received by that other client/socket with... socket.on('otherEvent', (msg) => { // do something with the msg }); Thanks for any clarity you can provide.

Helpful video, i was trying to import socket.io-client but it keeps getting an error failed to resolve module specifier ‘socket.io-client’, is there a way to solve this?
it would be great if you do your videos using react instead of html its only my humble opinion .. but is easier to apply it to real world projects thanks for you content men you are awesome !
hey great video,for some reason tho i cant get socket io to be imported into the client js file so when i run it locally it says "Uncaught SyntaxError: Cannot use import statement outside a module".
You need to add either this attribute in the script tag or in the package.json file to get rid of that error:- { "type": "module" } Or That is because the import statement is introduced in the es6 version and by default all you js files are in text/javascript type. So, you can unlock that functionality with this.
Hi Kyle, I really love your videos, you've been helping me a lot these past years. Is it possible to run a Socket server in Nextjs app router? If so, please make a video on how :) Thanks!
One question - when i call emit callback on sever - this callback has access to the context where it was declared? Or how it know what displayMessage function or document object is in this example?

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
Thanks a lot for your video, but i have an understanding problem: 1. The socket id is regenerated when you redload the page right?, so how can you identify a client (user), if the id changed? 2. In a real world application with multiple users, the nodejs script has to run on a "real" hosted server right? Thats confusing me :-) Thanks a lot!
1. we can get around that, after the ID is created you can hard code it to a specific ID [with combinations such as DeviceId & other encryption key ] which will be same until the code/logic is changed. So next time it can be recognized by other instances 2. Yes that will definitely need a backend.
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

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.
Brief. Concise. Succinct. No waste of space. Beautifully taught.
If "xhr poll error" still appears after setting admin socket ui like in the video then set credentials property to be true in the io server.
This comment means that you add "credentials: true" to the object cors when creating the variable io. I also faced an error "invalid namespace", in order to fix that you just have to remove the "/admin" part from the end of the server URL (so it is just localhost:3000)
Great tutorial. Really covers the foundations clearly and concisely. Thank you very much.
