How to use Zap in init()?

[albert-csms]

I have initialized Zap's SugaredLogger in cmd/server.go, and have been passing sugar to other files like so

	router.Handle(
		"/special_request",
		xray.Handler(
			xray.NewFixedSegmentNamer("my_service/special_request"),
			http.HandlerFunc(endpoint.SpecialRequestWrapper(sugar)),
		))

However, in one of my endpoints, I need to use zap in init(). I cannot use Go's log package because it does not provide logging at the warning level. How can zap be used in an init() function?

Hello! To use Zap in init, you'll have to initialize Zap before that init runs—probably in a module that imports it.

Following that, you need to have the logger available globally. You can have your initialization logic put it in a global variable, or use Zap's global loggers.

To use Zap's global loggers, call zap.ReplaceGlobals with your initialized logger. You can then access the SugaredLogger at zap.S().
