Hi Fellow Devs! In this tutorial, we are going to be looking at how we can use WebSockets within our own Go-based programs to do some cool real-time stuff.
By the end of this tutorial, we should have covered the following:
* What WebSockets are
* How we can build simple WebSocket Applications in Go
For the purpose of this tutorial, we’ll be working with the gorilla/websocket package as I’ve used it personally in a few production applications to great success.

A slight update to the code - Move the CheckOrigin check to the upgrader struct so that there isn't a data race: var upgrader = websocket.Upgrader{ ReadBufferSize: 1024, WriteBufferSize: 1024, CheckOrigin: func(r *http.Request) bool { return true }, }

Didnt watched it right now, but currently am into this topic. Next video, please incorporate gRPC protocol buffers. Like.. receive nested JSON from WebSocket and Unmarshall into ProtoBuf and back - feed protobuf into websocket as JSON. :)

Thanks for your comment! I will certainly look into doing a gRPC video in the near future!

Hello, thank you so much for this tutorial, can you please extend it to validate clients, authorization and some kind of identification for passing json between? Could be so nice.

Thanks for the tutorial, i have a error, when I run command "live-server" its shows an error command not recognize. Thanks in advance

@Ankitbalyansf 3 жыл бұрын

you need to install it as npm package as `npm install live-server -g` www.npmjs.com/package/live-server or you can simply use ` python -m SimpleHTTPServer` but it won't reload automatically, you'll reload you browser on changes.

Hey, I tried to implement websockets into my existing go web app but when the client browser attempts to connect the server issues this error message: Endpoint Error: websocket: response does not implement http.Hijacker. A bit more about the web app ... I'm using scs (Session Manager) with all routes. However if I take out the scs, the client connects without error. So my issue seems to be with the scs SessionManager. Any ideas as to how I implement HiJack? I cannot find any solid demonstration.

This isn't a tutorial. You just keep telling us what you're writing, everyone saying thanks for the tutorial means thanks for the code that does what I want - not thanks for the lesson. There aren't any. Why are you logging fatal to listen on the port? why are you passing nil as the second parameter? what are the pages functions parameters for? what's the siginificance of read/write buffer sizes? A tutorial isn't just a continuous announcement of what you're writing. Thanks for the try anyway bud, i'll be keeping an eye on these, see if the recent ones etc have gotten better :)

When creating educational videos, there is a fine line between offering too much detail and offering too little detail. I could go into far too much detail and lose the majority of my audience by spending an hour discussing how to build a WebSocket service, or I could provide the fundamentals needed to get up and running and cater to a far wider audience. Some videos are indeed too much for novices to the language and that's fine, I won't be able to cater to every specific person's needs, but the goal is to provide the most help possible to as many people as possible. If you would like to know more about these topics then I am always open to suggestions for new content in the future.

@sean You're a big boy mate, obviously if you're doing websockets that means you already have an OK level in that language and you can follow along with the basic explanation. The majority here are happy about this tutorial (including me) so I think the video does its job correctly!
