package main

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

    ctx.HTML("Hello <strong>%s</strong>!", "World")
  })

  app.Listen(":8080")
}

With your help, we can improve Open Source web development for everyone!

The only requirement is the Go Programming Language.

$ mkdir myapp
$ cd myapp
$ go mod init myapp
$ go get github.com/kataras/iris/v12@latest # or @v12.2.10

$ cd myapp
$ go get github.com/kataras/iris/v12@latest

$ go mod tidy -compat=1.21 # -compat="1.21" for windows.
$ go run .

Iris contains extensive and thorough documentation making it easy to get started with the framework.
