Iris is a fast, simple yet fully featured and very efficient web framework for Go.

It provides a beautifully expressive and easy to use foundation for your next website or API.

package main

import ""

func main() {
  app := iris.New()

  app.Get("/", func(ctx iris.Context) {
    ctx.HTML("Hello <strong>%s</strong>!", "World")
