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.
Which packages do you recommend for building cli tools?

Cobra and Viper.

I've mostly been using https://github.com/spf13/viper of late for my go projects. It supports the standard config formats, (json, yaml, toml etc) and lets you override any value with a ENV value.
Two ways to provide configuration: command-line, yaml file.

Not only that, the "unmarshall to struct" method doesn't work at all for environment variables. https://github.com/spf13/viper/issues/188
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
Ultimate config for Go applications

Is this sufficiently better than https://github.com/spf13/viper to warrant a switch?
[QUESTION] - How would I Read from multiple config files and environment variables?

Ya, I think this issue explains one of the problems: https://github.com/spf13/viper/issues/761

How To Work With Multiple Go Files?
2 projects | reddit.com/r/golang | 2 Feb 2023
There are some Go packages that can make config easy such as Viper or what I'll do in some of my quick/simple projects is to have a Config struct that I load from a JSON file. You can .gitignore the JSON file, and have your program on first startup write a default JSON file with some sensible default settings (like randomized secret keys for your cookies or JWT tokens and await only your database and email credentials to be filled in).
In NodeJS I can encapsulate different start-up command for different mode (dev, production) with package.json. then after that it will get the .env file for the correct environment mode. How to archive the same things in golang ?

I'll also add that we set our configuration as structs, and use https://github.com/spf13/viper to load the structure from TOML.
We haven't tracked posts mentioning config yet.
Tracking mentions began in Dec 2020.
