App init and graceful watch lib recommendations ?
For configuration, I like Koanf.
-
Two ways to provide configuration: command-line, yaml file.
Of course. You should always use a good config package. caarlos0/env is okay but https://github.com/knadh/koanf is a better all around solution imo.

Golang equivalent of Python’s click (CLT framework)
You can also use Viper with urfave/cli, or you can replace Viper with knadh/koanf, which I personally prefer.

Viper – Go Configuration with Fangs
Use viper with care. It has some dangerous fundamental flaws [1]. We got bitten hard, submitted a PR [2] and followed up for a year and a half to no avail, before I went ahead and reinvented the wheel and wrote koanf (plug), specifically to avoid viper's flaws.
Most importantly:
- Breaks JSON, YAML, TOML etc. language specs by forcibly lowercasing all keys internally. Dangerous because it can silently merge differently cased config keys into lowercase.
- Hard codes big unnecessary dependencies into the core, significantly bloating build sizes. No separation or abstraction.
- What are some good open source project to read when learning Go?
-
Coral, a friendly Cobra fork with nearly all its features, but only 4 dependencies
Came across this the other day https://github.com/knadh/koanf as an alternative to Viper.
-
What are your favorite packages to use?
https://github.com/knadh/koanf for config management. Readme contains why it's a good alternative to viper.
-
Is Viper necessary if my app is only using environment variables?
I use Koanf, much simpeler with the same options https://github.com/knadh/koanf

I've been using "caarlos0/env" for nearly 4 years? Anything better?
Personally I like: https://github.com/knadh/koanf
