// This example is equivalent to the
// https://github.com/kataras/iris/blob/master/_examples/hello-world/main.go
//
// It seems that additional code you
// have to write doesn't worth it
// but remember that, this example
// does not make use of iris mvc features like
// the Model, Persistence or the View engine neither the Session,
// it's very simple for learning purposes,
// probably you'll never use such
// as simple controller anywhere in your app.
//
// The cost we have on this example for using MVC
// on the "/hello" path which serves JSON
// is ~2MB per 20MB throughput on my personal laptop,
// it's tolerated for the majority of the applications
// but you can choose
// what suits you best with Iris, low-level handlers: performance
// or high-level controllers: easier to maintain and smaller codebase on large applications.

app := iris.New()
// Optionally, add two built'n handlers
// that can recover from any http-relative panics
// and log the requests to the terminal.
