He doesn't time pass, but goes straight to the point.

I'm gonna go make Twitter now

This is perfect for what I needed for my website. I'm definitely gonna put this to use. You da man.

Real-time sockets are so awesome. I love how it's all built around the publish and subscribe pattern too. So easy to follow along. Awesome tutorial, thanks!

This is exactly what I needed man, thanks! I've been trying to use arduino with johnny-five and web sockets for a while to be able to change the color of an rgb led from my phone, and this has helped a ton in seeing how web sockets work. Awesome content!

We used this tutorial and now we've come such a long way! Thank you web dev simplified!

thank you for having tutorials that does not go beyond 20mins. more power to you man

Normal people: social distancing Developers: socket io chat

That intro was great! I love your sense of humor in these videos :).

excellent as always!! You are the best company on afternoons that I want a break and to just have fun with a project and learning new things!!

"and that is going to be easy" - Quote of this video

Succinct, lucid and a calm, soothing explanation. You are an ideal tutor. Enjoyed the video very much.

perfect. no much talk, no blabla, only what you need to know

Priceless content Applause from Hong Kong student XDDDD

FINALLY! A good tutorial that ACTUALLY is what i was looking for! thankyou soo much!

*EDIT:* I have solved the issue. He npm installed a deprecated version of socket.io (2.20) so it seems this code no longer works with the latest version (4.1.1) Will have to consult the socket.io docs to complete this project. Edit 2: Still no luck getting socket.io v4. to work. *The problem* At 6:30 I do not get the socket.emit to log "hello world" in the console, so the socket wasn't working right. Finally I tried copying his github code and the app doesn't work (you an only see your own chats.) So I thought it might be different syntax for sockets 4.0 and above and we need to consult the docs, or install an old version of socket.io. Then I confirmed that version 2.20 prints hello world to the console. *tldr:* He installed socket.io 2.20. The current version is above 4.1.1 and this code won't work right with the new version.

Thank you bro!!! this is what i'm looking for, no templating engines or frontend frameworks just native.

Hey nice channel, I like the way you explain programming and how clear you manage the information, will you extend this topic using a different app, not a chat, mb a real time post update or a new DM receive??

I have made my first Javascript& Node.js project 😊 Thank you very much!

I've said it before and I'll say it again, you're a very smart young man :)

cant believe i faced click bait on other videos like THIS..... THANKS A LOT..subed

This is amazing, what I'd be interested to see is a live ticker application e.g. for a football game

I'm just learning node and express...etc because of my future, then I got a good page finally so I'm really thankful for this opportunity

That's really nice and well explained! You got it straight to the point. My only question is - do you run this over Express server? you browse localhost:5000 yet the IO variable gets the 3000 port as a parameter. This is something you didn't explain.

i am very new to javascript... i didnt understand anything.. but i believe that after 6 months i will be clearly able to understand it... thank you

I keep on getting CORS error in console

That is so awesome! God bless you, man!

This is exactly what i was looking for!

This guy makes node js look so easy..

Your Intro's are pretty cool...👍👍

I need answers for the following questions, can you please answer this (1) Did you observe how it became INSTANT messaging? Is browser client making so many frequent calls to backend to get instant messages? If so, it will be a huge traffic onto the backend server with heavy load. Is this what happening? I am verifying whether you understood the concept, Pavan. (2) Did you try having two different groups having the chat at the same with total isolation from each other? That means you and Varma can have one. On the same server, at the same time, me and another person can have the chatting too. (3) And it should be persisted in database so that it can be always visible when they come back some other day and continue chatting.

Access to XMLHttpRequest at 'localhost:3000/socket.io/?EIO=4&transport=polling&t=NN_PVjI' from origin '127.0.0.1:5500' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. I got this error why?

This was very helpful to start with the basics! I have subscribed to this channel and would go through the rest of the content. Thank you :)

May I ask how the index.html is being views on port 5000

Wow! That was awesome and I loved it! Hoping for more amazing content!!! 🤓🤓

thanks so much for the tutorial, i always had a lot of trouble doing the networking stuff and this helped me a lot!

For the noobies out there like myself, you need to reboot your computer after installing node.js. Otherwise, you will get an error message like the one below after trying to run "npm init" from the terminal: npm : The term 'npm' is not recognized as the name of a cmdlet, function, script file, or operable program.

CORS ERROR FIX: In server.js file "const io = require('socket.io')(3000, ( cors: { origin: "*" } } );"

I'm confused by this. you never actually set up a server that sends the index.html file. How is the page loading in this example ?

Short videos ftw. Cheers buddy, subscribed

Can you please explain the address bar "127.0.01:5500/index.html", that would be helpful." Like where exactly you have kept your (index.html) file/s. And directory structure of the same.

Best Intro EVER!

CORS Problem how to fix it

Best video to understand the basic of socket.io library 💖

Bruh, what the heck you doin in this computer stuff!!! Go get Hollywood contracts!! You look like a god😍

Thank you so much for this. Please make a tutorial video showing how we can create PWA chat app ? Great work dude! I speak for all newbies out there when i say... THANK YOU!

Guys this man is a legend thank u

Thank you dude, that was amazing!

You have explained in a superb way bro.. Keep doing these amazing videos...

I am not getting the mesage in my console when I press send 9:33

Awesome video! Thanks! Can you also make a tutorial on how to deploy it? (On AWS for example)

Great thing is, you've done it in under 20mins.

What do you do about the CORS error?? I've tried to find answers on google but i don't know how to implement it into my code...

Hey Kyle what a great video. I have a running Apache server and a Mysql server running from scratch. Now I want to hook up my Database to this chat server. Then I will have 3 ports all doing something important. LOL I love a challenge.

I always wondered how chatting works... Awesome content and thanks a lot!

I found this easy to follow, however I am having issues with starting the server as well as getting socket-io to import properly. I had to add a http-server command I found online to get the server running. I believe I followed the proper instructions (even downloaded the source code and ran that) but I'm also getting these 'io is not defined' errors, even though I ran npm install socket-io. Any tips? Thank you!

Loved the intro

Great video! after scrolling the comments to see you are using live-server i now seem to be getting lots of CORS errors in the terminal when trying to run in browser

I can not see "Hello world!" on the console :( I also don' t get an error I get this in issues.: "Indicate whether to send a cookie in a cross-site request by specifying its SameSite attribute"

This is great for my school project. I think I now have a better idea of how to do it thanks!

Amazing tutorial, everything was well explained, thanks!

Great topic. It's easy to understand from you. Thank you.

Thanks for this. I was looking for an example to work through to help me learn about connect.io. This has worked well,

Perfect tutorial. Thanks again

I'd love to see a more advance project with socket.io thank u for explaining ! Appreciate it

I have implemented my messaing service using you tutorial thanks alot!! I have a blocker though, I'm trying to create a channel where in a master user can send the message to multiple selected users. I'm not sure how I can create a dynamic channel and listen to it only for the user whom the master user sends the message
