How To Build A Chat And Data Feed With WebSockets In Golang?

In this Golang tutorial, I'm going to teach you how to build a simple chat application and data feed by building our own custom WebSockets server in Golang.

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

[manofqwerty]

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

[nefrace]

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.

[VitaminessBlues]

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

[matthewthomas]

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!

You have a new subscriber. Thanks Anthony!

[gadgetboyplaysmc]

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!

[sweetphilly]

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

[crisgomez]

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

[raspberrysans]

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

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?🥺

[Cryoxia]

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

[michelemendel]

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

[AssyrianMuscle]

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?

[sumonsutrodhar]

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

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

[TheNickeHallgren]

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?
