Love that you go in showing the concepts without a bunch of libraries. Keep it simple and then abstract later if needed!

this channel is hidden gold

I have never looked into sockets and always thought they would be really complicated - thanks for this!

You've just single handedly motivated me to learn Golang more than I usually did. This series of tutorials are awesome and I really appreciate this simplicity and minimalism of using standard libraries as much as possible.

Like your style! Speed of speech and simplicity of explanation make it lit! Awesome!

One thing I love about your videos is that you're going right to the point

All great videos and not just that your a very funny chap, which makes the videos more relatible then someone just saying do this and that. Keep it up!

This channel is a gold mine.

Great video. Big Thanks!

You have a new subscriber. Thanks Anthony!

Amazing Stuff, Let's Go😎

I have subscribed. You make it look easy. I have no idea how it works because I come from TypeScript. The function syntax sort of is a little new to me. The map, create whatever is also all new to me. But will be studying this code. Thanks for this. Hope you make more useful content! Thanks!

I don’t know Go but I don’t need to. I learned so much from this video, thank you!

Good stuff!

Great tutorial. A bit fast for my liking but it gave me good insights. Would've like to see a thread-safe implementation of the connection map, but I'll research that on my own

Bro you doing great

So helpful, thank you. 10/10

Awesome stuff

oh thank you very much for making this tutorial, I had been looking for a good one, and you explain it quite well, and the best thing taught by Jhony sins

thanks for the sharing

Fantastic

Netflix for Software Developers, proven content creator!

but REALLY you SHOULD get the Nobel Simplification Prize bc you explained so well! Thank you, sir :)

Thank you Anthony

thank you.

appreciate the zoom

very awesome tutorial GG, but i may have some problems with the websocket Write() method. Since I do it step by step with your video(just SAME as your code), i can't figure out that why the server can't write to the browser, no matter the first /ws or the later /orderbookfeed, it turns out the console don't print the message from the server after setting up the onmessage method, what's wrong?🥺

awesome

Could anyone tell me where you get info on the errors returned by library methods? In the video, he talks about Conn.Write returning EOF, but I can't seem to find the info on the golang site

respect

Again, very nice. Could the actor model (e.g. your Hollywood library) be used with websockets, or would it be unnecessary?

Hello, I have a question. My server response 200, and seems all working fine, however in my browser I got 403 error... Any ideas how to fix it?

Brother can we get some architecture style vids? Or your opinions on them (hex, clean) or even ddd in golang? Maybe some design patterns that you think work well specifically with go?

hello. this video is very good. how to create tcp socket chat client / server custom protocol

GG, I appriciate when you care about the blind homies. 🤓

Coould you please introduce tuntap packet reception and transmission for user space programs? TIA

Excellent tutorial! How do I remove clients that have disconnected, as now they are still on the conns map after disconnecting and the next broadcast gives an error for use of closed network connection?

Oh yeah, a golang websockets online class with johnny sins.

This video made me feel old 😂

He can easily make joke about high-end industry topics, as he has full control over the topics.

there is a subtle bug, will take you hours to find it if you dont know whats happening underneath.. basically, you are not guaranteed that your messages come unchopped! just implement a message terminator and read until you encounter a message terminator, which may require 5 reads, for example and once you have all the fragments of 1 message, you can process the message! otherwise its incomplete, probably not a big issue in a chat app, but very problematic when you are transferring structured data!

lmao the 1337 😂

Thanks for your videos, very useful. My only tip is to slow down with your typing, to make less typos. Slower typing will also help the viewer have some more time to understand what you are doing and take in what you saying. I know, it might be difficult to slow down if you are naturally a quick typist.

You can't fool me Johnny Sins, you typed something else at 2:06

Didn't know Johnny Sins is into coding

code link ?

my Holy Grail port: 81

how would I connect to this server from another computer?

your furiously fast typing + all the mistakes == me every time i know what i am actually trying to do my heart when i'm programming and just trying to do it fast af lol. When i don't know what i'm doing by heart i make 0 mistakes

I was searching for silver & found gold

:8080. Definitely 8080!

ah huh you could have deleted the connection from conns on EOF

Age, sex, location.

Age, sex, location?

Dafuq is heish

what about Content-Security-Policy?

I think that can be improved your current implementation does not work: i did this: err = websocket.Message.Send(ws, "gracias amigo for el mensaje!!") if err != nil { log.Printf("write error: %s", err.Error()) return }
