I write HTTP services in Go after 13 years (Mat Ryer, 2024)
I found fx(https://github.com/uber-go/fx) to be a super simple yet versatile tool to design my application around.
All the advice in the article is still helpful, but it takes the "how do I make sure X is initialized when Y needs it" part completely out of the equation and reduces it from an N*M problem to an N problem, ie I only have to worry about how to initialize individual pieces, not about how to synchronize initialization between them.
I've used quite a few dependency injection libraries in various languages over the years (and implemented a couple myself) and the simplicity and versatility of fx makes it my favorite so far.

Gorilla,wow
any take on https://github.com/uber-go/fx?

App init and graceful watch lib recommendations ?
I’m not sure of much that can do all of that - maybe it’s a use case for https://github.com/uber-go/fx

How normal is it to stare at your screen, getting nothing done when stuck and waiting for help?
If I still find myself stuck/waiting, I switch over to studying more about our team's main language Go. Currently looking around at Fx ( https://github.com/uber-go/fx ). Which is interesting, though I doubt we'll actually migrate anything for it, but might make a neat lunch and learn topic.

Zerolog printing logs multiple times
Hello gophers, I am using https://github.com/uber-go/fx and https://github.com/rs/zerolog for logging.

Does this project structure make sense?
Also, I like to use Uber FX for my DI stuff. You can check it out here:https://github.com/uber-go/fx

As a Go programmer, what design pattern, programming techniques have you actually used, implemented regularly in your workplace which made your life much easier?
I only have private and work repos... But I use Uber fx. https://github.com/uber-go/fx

Does Golang has any framework like Springboot?
Spring Boot is notable for its dependency injection / inversion of control. The closest Go has to this is Uber's Fx which also includes some lifecycle management.

Config for production and mocking (db connections, http parsers etc)
If you have such a complex and deep dependency graph, and you don't want to manually maintain it, you could use some DI library to handle that for you. Something like https://github.com/google/wire for small-medium size stuff, or https://github.com/uber-go/fx for larger scale, more enterprise projects.

Good Books for a GO Beginner in 2023/24
Go never changed as much as Java does in each major release, so old books are still relevant. https://www.gopl.io/ is fine if you read about generics and some new standard library modules somewhere else later.

Is go worth studying as first language?
The GOPL book is good one to start with, if you prefer reading books. https://www.gopl.io/

Does anyone have any good resources to practice channel, context, and goroutine?
Not that they are leet code style, but some exercises from "The Go Programming Language" are really worth having a look at, also most solutions are available at https://github.com/adonovan/gopl.io
- Best way to learn GoLang for Java Developers?
- How similar is GO to C?
-
is go still simple?
What part(s) are you struggling with and how are you learning? The Go Programming Language is slightly outdated but is an excellent intro. You can read the first chapter free. Also the resources on https://go.dev/learn/ are great. If I were you, I would come up with an idea you're excited about and build it.

Learning about concurrency
For a deeper dive, I’d recommend The Go Programming Language - a fantastic resource covering a broader landscape of the language than just concurrency.

If you want to learn Golang - please go through "Go Programming Language" by Brian Kernighan and Alan Donovan
"Low-level programming" is chapter 13, both in the version I have and on https://www.gopl.io/ -- the rest is all somewhat crucial stuff, except for maybe reflection.
