What's the difference between single and singleby here https://github.com/InsertKoinIO/getting-started-koin-ktor/blob/master/src/main/kotlin/org/koin/sample/HelloAppModule.kt#L8

[diesieben07]

It's the bound type. single binds to the type you give it (HelloRepository in the example), singleBy creates the 2nd type (HelloServiceImpl), but binds it as the 1st type (HelloService).

[diesieben07]

The "by" can be used as a hint:
"Provide a HelloService by using `HelloServiceImpl`"

singeBy is a way to declare without any function. It uses reflection here

[diesieben07]

So does the version of single in this example
