Learn Socket.io In 30 Minutes

[@djameleddineMOUMEN]

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.

Amazing and accurate comment!

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.

[@br2716]

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

@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!

[@davidobodo3605]

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 agree. Very professional. Well paced. Fast but not too fast.

[@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.

[@prajwaltulawe6725]

[@TheCodeAngle]

Good presentation and delivery. Well done!

[@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

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.

I just thought of a project that needed web sockets and i get a notification of this video

[@ismail.dalhatu]

Thank you kyle I was struggling with web socket when I saw this notification

[@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.

[@forcowicz5830]

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

[@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");

[@professorice4325]

Using this for a gambling site. I'm barely in but seeing your intro "No Stack to Full Stack" made me laugh. Very Clever

[@avi_mukesh]

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.

[@inoorbeats7632]

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.

[@mukkupretski]

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)

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!

[@germanmartirosyan6230]

The best socket io video ever! Thank you!

[@hekskey]

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.

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".

[@asimkoirala8074]

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.
