Import func from subfolder

I'm trying to import a func from a subfolder.

I have a main package

package main

import (
    ...
)

func handleRequests() {
    http.HandleFunc("/health", health)
    ...
}

func main() {
    handleRequests()
}

And then I have a folder called health in which I have a file called health.go.

package health

import (
    ...
)

func health(writer http.ResponseWriter, _ *http.Request) {
    ...
}

What shall my import look like and how do I call my health func?

At this point, your import statement doesn't mean anything, because it health package has no exported function or variable. You should check out the scoping in Go from the language spec. From here

Maybe consider checking out go modules, since it is now the suggested way to handle any go program that has more than a file.

The quick answer is,

your health.go

package health

import (
    ...
)

func Handler(writer http.ResponseWriter, _ *http.Request) {
    ...
}

your main.go

package main

import (
    github.com/blablabla/yourproject/health
)

func handleRequests() {
    http.HandleFunc("/health", health.Handler)
    ...
}

func main() {
    handleRequests()
}

You must name function starting from uppercase symbol ("Health" instead of "health").

For example: health (your case) is private declaration, and Health would be public.

The same principle with types and variables naming.
