// It seems that additional code you

// 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.
