Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Go 1.22 Release Notes
On the other hand, I advise you NOT to use this kind of library and write simple, fast go code most of the time, with the occasional generics helper. Why the hell would I clutter my code with, for example: https://github.com/samber/lo?tab=readme-ov-file#fromentries-...

Go is not an easy language (2021)
This wasn't feasable without generics, and now with generics they're already adding some convenience functions to the stdlib, like in the slices package.
For map, reduce etc it's not in the stdlib yet, but you can use https://pkg.go.dev/github.com/samber/lo
- I wrote a for loop so you don't have to. Parallel Map, Filter, Reduce library

What is your recommendation for a package beyond std?
In particular, I'd like recommend samber/lo, this is a lodash generic tool for golang.

What 3rd-party libraries do you use often/all the time?
What are some 3rd-party libraries for Go that you use often/all the time? Instead of "just implement everything yourself", I would really like to get some tips. For instance, a few days ago I discovered https://github.com/samber/lo , which looks very good if I want to have list comprehensions (Python) / LINQ methods (C#). https://pkg.go.dev/github.com/atotto/clipboard is also good for clipboard operations. What else do you suggest and for what task?

Functional Programming Library for Golang by IBM
A simple alternative is the combination of:
- https://github.com/samber/lo
- https://github.com/samber/mo
The split is also nice as you can choose to just use the generic convenience functions from lo without the more FP related things from mo.

In what ways are channels are better than the traditional await?
Some packages offer utilities to gather results from goroutines, such as multierror.Group or parallel.Map in samber/lo.

samber/lo utility package based on generics
I came across samber/log a package based on generics for providing utility methods.

Finding unreachable functions with deadcode – The Go Programming Language
One of the checkers in golangci-lint does this. I forget which one.
golangci-lint rolls up lot of linters and checkers into a single binary.
There is a config file too.

Using Private Go Modules with golangci-lint in GitHub Actions
golangci-lint is an amazing open-source tool for CI in Go projects. Basically, it's an aggregator and a Go linters runner that makes life easier for developers. It includes all the well-known liners by default but also provides an easy way to integrate new ones.

Show HN: Error return traces for Go, inspired by Zig
The "standard linter" in Go is https://golangci-lint.run/ , which includes [1] the absolutely-vital errcheck which will do that for you.
For an Advent of Code challenge you may want to turn off a lot of other things, since the linter is broadly tuned for production, public code by default and you're creating burner code and don't care whether or not you have godoc comments for your functions, for instance. But I suggest using golangci-lint rather than errcheck directly because there's some other things you may find useful, like ineffassign, exportloopref, etc.

Hacking Go to give it sum types
golangci-lint recently integrated go-check-sumtype. I recommend using golangci-lint as a pre-commit hook, but if you're in a real hurry you can replace "go build" with a shell script that runs go-check-sumtype instead. This is probably better than a weird hack, not that you're saying that the weird hack is a good idea anyhow.

Structured Logging with Slog
This is such an infuriating problem. I'm convinced I'm using Go wrong, because I simply can't understand how this doesn't make it a toy language. Why the $expletive am I wasting 20-30 and more minutes per week of my life looking for the source of an error!?
Have you seen https://github.com/tomarrell/wrapcheck? It's a linter than does a fairly good job of warning when an error originates from an external package but hasn't been wrapped in your codebase to make it unique or stacktraced. It comes with https://github.com/golangci/golangci-lint and can even be made part of your in-editor LSP diagnostics.
But still, it's not perfect. And so I remain convinced that I'm misunderstanding something fundamental about the language because not being able to consistently find the source of an error is such an egregious failing for a programming language.
