KZfaq API Overview - developers.google.com/youtube...
Text Tutorial: tutorialedge.net/golang/build...
Hi Everyone! In this tutorial, we are going to be having a bit of fun and we are going to be creating a real-time KZfaq stats monitoring system in Go.
So, we are going to be looking at a number of different topics within this tutorial such as creating a WebSocket server and using WebSockets to communicate in real-time with a frontend application, as well as how you can interact with an existing REST API to get the subscriber stats we need.

Hope you all enjoy this latest tutorial! I missed explaining how you set environment variables! You can do this using the export CHANNEL_ID=UCwFl9Y49sWChrddQTD9QhRA export KZfaq_KEY=YOUR-KZfaq-API-KEY on MacOS or using the set command on Windows!

Awesome tutorial, thanks... quick question: when are you going to create a Go video course? so you can show us the potential in real world backends.

Hey thanks for the video. Does the for range on the ticker no block? So why do you need the infinite for loop? What you could improve on as far as the videos is adding some camera movement focusing content you are talking about. Right now there is almost half the screen just sitting there and the code is a little small. A great example would be watching the laracasts tutorials

Hi! Thanks for the insightful tutorial! One issue I found that the final part (client accesses to the ws), it currently returns 400 status and the message is like this: "websocket: the client is not using the websocket protocol: 'upgrade' token not found in 'Connection' header", is there any configuration required to start handshaking? or do you know what is causing this status error? (I believe func Upgrade returns nil but not sure why) Thanks in advance!

Hey, I believe it is called cobalt2 by Wes Bos! I am out and can’t double check at the moment unfortunately

Hi, the official documentation has a lot of steps to integrate with KZfaq api, can u tell why is it so if it can be accessible with API key only?

I wish you'd have stuck to the standard library and not Gorilla so I could maybe understand a bit more about websockets, but thumbs up for sure!

Hi, I am a beginner. It'd be helpful to see what is inside go.mod file?

@BNakato 5 жыл бұрын

I am a newbie to Go and this might be Go syntax but is it necessary to check for error on each function call or is there some sort of try catch.

@joaofnds 5 жыл бұрын

Basically yes, that's the "idiomatic" way of doing it in go. Everyone has some mixed feelings about it when learning Go, but if you think about it if something is telling you that it may fail, why wouldn't you deal with the error?

At 12:58 you should really check the length of Items. It is possible that the API is broken or hits and error and you are returned with zero items.

@Tutorialedge 5 жыл бұрын

good catch! Ideally you would also catch the status of the response as well to ensure you weren't hit with a 403 unauthorized response or something else outwith the "happy path"

Is it just me, or did you forget to explain how to set up the environment variables?

I did, check out my pinned comment for this video! :)

Did not like that you do not explain why you pass which parameter :) "I forgot to add nil here" - well, why is nil needed here? Of course, I could look up the documentation, but in a tutorial, I'd expect this to be told. But otherwise interesting tutorial!
