App init and graceful watch lib recommendations ?

• appctl

  1 20 4.0 Go

  Application Controller

Is there any lib to init the app (read config from yaml, db.. ) and control it's gracefully shutdown? I found this one https://github.com/iv-menshenin/appctl - which doesn't have init thing, but instead has ping service. Was wondering are there any de facto standard libs to do that ?

• fx

  31 5,284 8.3 Go

  A dependency injection based application framework for Go. (by uber-go)

  

I’m not sure of much that can do all of that - maybe it’s a use case for https://github.com/uber-go/fx

• run

  7 1,477 4.5 Go

  A universal mechanism to manage goroutine lifecycles (by oklog)

  

What I’ve done in the past is use a run group (like https://github.com/oklog/run ) and one of the goroutines in the group is just listening for a SIGINT/SIGTERM/etc. When it sees that it throws an error which cancels the root context and let’s each component handle its own graceful shutdown
