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.

Visualizing Diffs The Myers difference algorithm
This made me think of a couple other interesting things:
1. you can change which algorithm is used in git diff as multiple are supported
https://luppeng.wordpress.com/2020/10/10/when-to-use-each-of...
2. Google has an edit graph implementation in Go in the cmp package

How do you do DB preparation in e2e tests?
Assertion libraries that people seem to love: - testify (my favorite) - go-cmp is a more barebones library - gotest.tools -- I have never used this but some swear by it
-
alecthomas/assert: A minimalist type-safe drop-in replacement for testify/require
it uses https://github.com/google/go-cmp instead of reflect.DeepEqual

What annoys you about Go?
When I use functional arguments, I either prefix all of the options with the same prefix or put them in a dedicated package (like cmpopts) to help the IDE.

Migrating from PHP to Go

What are your favorite packages to use?
oklog/ulid to generate IDs. coreos/go-oidc for validating JWTs I get from auth. google/go-cmp for comparing structs in tests (unless the project is already using Testify). spf13/pflag because life's too short for Go's flag handling. getkin/kin-openapi for validating reqests/responses against my OpenAPI spec (in tests).

Go Package for Equality: github.com/google/go-cmp
One thing to keep in mind about reflect.DeepEqual is because of the way it is implemented you could get positive results when the values are not actually the same, see this comment for reference.

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?
Testify - A toolkit with common assertions and mocks that plays nicely with the standard library
zap - Blazing fast, structured, leveled logging in Go.
ginkgo - A Modern Testing Framework for Go
logrus - Structured, pluggable logging for Go.
go-testdeep - Extremely flexible golang deep comparison, extends the go testing package, tests HTTP APIs and provides tests suite
lumberjack - lumberjack is a log rolling package for Go
JSON-to-Go - Translates JSON into a Go type in your browser instantly (original)
glog - Leveled execution logs for Go
godog - Cucumber for golang
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.
assert - A simple assertion library using Go generics
log - Structured logging package for Go.
