How To Build A Custom TCP Server In Golang!?

In this Golang tutorial, I will teach you how to build a custom TCP server that can read from and write to incoming connections by just using the standard library.

Holy Shit...Just few days before your Subs. Were 2k now it's 3k .. Congratulations Anthony for This Badass videos🍻

Good example, but there is a major bug in the code: The "buf" slice is being reused, but the buf is not copied before it's sent to the channel (msgch). buf[n:] only creates a new slice pointing to the same address but with a different length.

TCP already comes with backpressure so I'm not sure how much use there is for the extra channel. But if you want to use a channel, allocate a new slice (buf) each iteration.

"I dont know how to close telnet"

It literally hints you how each you make a connection.

"Escape character is '^]'."

that is "control-]"

Then you will get a telnet> prompt ... type "quit"

Hi, I want to thank you by providing this tutorial, It helps me a lot. May I confirm something? Is the reason you put goroutine of readloop() inside acceptloop() is for handling multiple message in the same connection?

So lets say you send a request to the server, but the server still can receive another request while processing the first request isn't it?

Please make video about your programming environment setup.

hey man, i loved the video, thanks a lot !

[regionkaz]

Thanks a lot! I like your style.
It would be interesting to watch about vim shortkeys that you use.

I didn't know GSP had a youtube channel about programming xD

[lokthar]

love your content again, when will you bring some Rust stuff? Also when would you pick Rust over Go and vice versa?

i have a question
at 07:15
as i understand, the for loop inside readLoop function will keep reading data from connection by using conn.Read
can we put read message process to goroutine?
what will be the different between using goroutine and not using goroutine at this situation?
thanks,

Quick off-topic question. Is it a good to idea to use TCP for my backend app so I can build native desktop GUI and use it? GUI connects to my go backend app via localhost tcp. Anyway, great video, will use it for my pet-project as an example. Thanks!

how about creating alternative open source for openssh

I got my channel back Anthony! Let’s do one where you teach me go and I teach you functional js

You didn't show how to use the quitch

[Scratchmex]

why do you keep moving your pointer when you are writing? it is very distracting haha. Apart from that good video!
