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.
logr
- What is the common log library which is industry standard that is used in server applications?
-
Created a small logging library in Go.

Logging Library
How about using https://github.com/go-logr/logr You’ll be able to swap concrete implementation easily which will allow you to try out different libs on the market without refactoring all your logic
-
Have you replaced Sirupsen/logrus, and if so, with what?
I recommend https://github.com/go-logr/logr and you can choose implementation freely but zerolog/zap are optimized for speed.

Version 1.18 Refresh for Go Programmers
For logging, I use https://github.com/go-logr/logr with https://github.com/uber-go/zap

Logger and Clean Architecture
I'd say it depends. If I write a package for others to use I usually don't include a logger at all and let the user decide what he wants to use. For any other project that needs logging I usually skip the interface to not have the struggle with finding one interface that fits all at least logrus and zap. We kinda agreed at the team to just use zap by now. One.thing i wanted to try tho is using sth like logr which provides an interface for the most commonly used loggers.

Go Masterpieces
After writing a lot of libraries I really appreciate logr. There are plenty of times when my library needs to output debugging info, but it's not practical to do things like parse flags for verbosity level. With thus I can just log at a higher V level and be done with it.

Go 1.21 Released
Be aware that there is a performance impact compared to using zerolog directly [0] (my uneducated guess is it is likely due to pointer indirection).

How to start a Go project in 2023
Things I can't live without in a new Go project in no particular order:
- https://github.com/golangci/golangci-lint - meta-linter
- https://goreleaser.com - automate release workflows
- https://magefile.org - build tool that can version your tools
- https://github.com/ory/dockertest/v3 - run containers for e2e testing
- https://github.com/ecordell/optgen - generate functional options
- https://golang.org/x/tools/cmd/stringer - generate String()
- https://mvdan.cc/gofumpt - stricter gofmt
- https://github.com/stretchr/testify - test assertion library
- https://github.com/rs/zerolog - logging
- https://github.com/spf13/cobra - CLI framework
FWIW, I just lifted all the tools we use for https://github.com/authzed/spicedb
We've also written some custom linters that might be useful for other folks: https://github.com/authzed/spicedb/tree/main/tools/analyzers

claim: qlog is faster, simpler and more efficient that slog; and does more practically useful stuff too
Can you compare it against zerolog?

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

Doubt around "Test only public functions" concept
Hovewer it is not bad to export such a function, if it is done purely for convenience. For example github.com/rs/zerolog works on a logger instances, which can be created manually, but they also provide a github.com/rs/zerolog/blob//log package, which provide you access to the global logger which is more convenient in most cases

Tools besides Go for a newbie
IDE: use whatever make you productive. I personally use vscode. VCS: git, as golang communities use github heavily as base for many libraries. AFAIK Linter: use staticcheck for linting as it looks like mostly used linting tool in go, supported by many also. In Vscode it will be recommended once you install go plugin. Libraries/Framework: actually the standard libraries already included many things you need, decent enough for your day-to-day development cycles(e.g. `net/http`). But here are things for extra: - Struct fields validator: validator - Http server lib: chi router , httprouter , fasthttp (for non standard http implementations, but fast) - Web Framework: echo , gin , fiber , beego , etc - Http client lib: most already covered by stdlib(net/http), so you rarely need extra lib for this, but if you really need some are: resty - CLI: cobra - Config: godotenv , viper - DB Drivers: sqlx , postgre , sqlite , mysql - nosql: redis , mongodb , elasticsearch - ORM: gorm , entgo , sqlc(codegen) - JS Transpiler: gopherjs - GUI: fyne - grpc: grpc - logging: zerolog - test: testify , gomock , dockertest - and many others you can find here

What is the common log library which is industry standard that is used in server applications?
I use zerolog myself and have seen it being used in production several times. Also they have a list of who uses zerolog

Log: A minimal, colorful Go logging library 🪵
This would be so awesome if it was extending an awesome logger like https://github.com/rs/zerolog. Personally I love zerolog because of how it handles different data types including structs!

Best Logging Library for Golang
logrus README recommended using other libraries such as Zerolog, Zap, and Apex.
- If you had to choose a logging framework, which one would you use?
What are some alternatives?
zap - Blazing fast, structured, leveled logging in Go.
life
logrus - Structured, pluggable logging for Go.
golog - Golog is a production ready logger which support tracing and other custom behaviours out of the box. Blazing fast and simple to use.
lumberjack - lumberjack is a log rolling package for Go
glog - Leveled execution logs for Go
log15 - Structured, composable logging for Go
Gin - Gin is a HTTP web framework written in Go (Golang). It features a Martini-like API with much better performance -- up to 40 times faster. If you need smashing performance, get yourself some Gin.
log - Structured logging package for Go.
