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.
@@jmgomw7787 why are you even triggered???, he is clarifying something that kyle didn't mention, maybe stop being such a douchbag and learn something instead.
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.
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.
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
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
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.
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.
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
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.
@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");
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.
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)
Outstanding bro, proud of ya.. , unlike the others they just copied someonelse codes and explain it with the official docs , too muc uh ah eh aswell, lol.
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!
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 ?
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
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?
Getting Error: xhr poll error and in console has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. while trying to get into admin dashboard....any help ??
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.

Needed this video to implement real-time features in my project. You explained all the things that are needed.
Thank You, Kyle.
I agree. Very professional. Well paced. Fast but not too fast.
Brief. Concise. Succinct. No waste of space. Beautifully taught.

@2:51 is very important. For the longest while I always thought that the socket connection died after each event.
Good job Kyle 👏🏽
Thank you for organizing everything about the socket! It's better quality than other paid lectures. Thank you very much!

I just thought of a project that needed web sockets and i get a notification of this video
Kyle Cook, the best teacher! 🤗
WDS the greatest channel on earth. I love the way you explain things. Its so easy to pick them up!
this is so timely. Im currently creating a messaging app using react. thanks for this kyle!
You saved my life brother.. 🙌
The way you solved the cors was just 😌
how can i get the set up code in 0:44 any link plz
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.
Hello, I live in Iran and your education is excellent ..
Thank you, this is a very in depth tutorial on socketio and you did a very good work with the examples
Perfect timing!
Thank you kyle I was struggling with web socket when I saw this notification
Loved it. In just thirty minutes, I have learnt so much. Kindly, make a detailed (advanced) version of this.
Using this for a gambling site. I'm barely in but seeing your intro "No Stack to Full Stack" made me laugh. Very Clever
Great tutorial. Really covers the foundations clearly and concisely. Thank you very much.
@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");
You're not only making great tutorials, but you are also a really good life coach I can say by watching some of your videos XD
bro you are a legend!, you teach things so simply thank you soo much.Keep uploading more and help us.
Thanks, and much love from Kenya, short and straight to the point,,

Need to adjust the speed@0.25X 04:25, swap to another terminal window; 04:35, run "npm start" in the clients side folder
Good job. This video is really helped me understand the basics of Socket io. Do what you'are doing and don't stop.
This is the best socket explanation I've found. Thanks!
This was an incredible, very easy to follow tutorial
Good presentation and delivery. Well done!
Thank you Kyle, this was just awesome tutorial, we need more like these 🔥🔥🔥❤❤❤
Duuude, I literally was searching for a good tutorial on this for like a week, and here you are!
Thanks a million!
Wow, you're so great in explaining things. Thank you!
thanks mate , you're really good at getting points simply to the head
Thank you to explain us, this topic a little bit hard to me before watching that video
May the Righteous and Holy force be with you Jedi Kyle. I definitely would like to implement this somewhere on my web space.
Dude you have no idea how much this has helped me!!! Keep up the good work and thanks man🍻🍻
Ultimate .... In such a less time what a golden information
WOW! Other than your Jedi lingo is faster than a light Saber, amazing stuff.
Always making me curious with new stack 👍
My resolution start learn only from this channel in order not to waste time.
Here he add cors which is work in socket 3.0 or above only..For below socket 3.0 u must use const io = require(socket.io){origins:[your_url]}
I've noticed you now speed your videos up by just a bit. Interesting approach...Anyway, thanks for this!
I don't speed up or slow down any of my videos
You are the G.O.A.T Kyle, Thank you soooo much for this.
He really went ahead and did it. Yeah the title of the video
Kyle what is the repo for this project? To kickstart to practice coding along.
Amazing content, whenever I need to learn some new stuff first place where I'm looking for materials is your channel. Greeting from Croatia 🇭🇷
You saved my career. Thanks a lot.
Would have been helpful to follow along if there was a template for the starting boilerplate code. Nevermind. Did it myself. Great tutorial though.
8seful and man you've explained amazingly...Thank you soo much 😍😍
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)
Awesome video! Thank you!
The best socket io video ever! Thank you!
This covers everything I need for my game project. Thanks 💯
