Dependency Injection Graph Example
This example illustrates how package go.uber.org/fx/dig can be used to inject
a dependency.
struct HelloHandler exposes a dependency on hello.Sayer but does not
provide any guidance of when or where to get it. On the other side package sayer
injects an implementation of hello.Sayer interface into the graph.
When the application is initialized, dig is asked to resolve the dependencies
of the HelloHandler and create an instance.
Run the example
$ go build
$ ./dig
$ curl localhost:8080
Well hello there DIG. How are you?
