Getting Started

After installing Go and setting up your GOPATH, create your first .go file.

package main

import (
	"fmt"
	"net/http"

	"github.com/nanoninja/drago"
)

func DemoMiddleware(next http.Handler) http.Handler {
	return http.HandlerFunc(func(rw http.ResponseWriter, r *http.Request) {
		fmt.Println("Demo Middleware Before")
		next.ServeHTTP(rw, r)
        fmt.Println("Demo Middleware After")
	})
}

func main() {
	mux := http.NewServeMux()
	mux.HandleFunc("/", func(rw http.ResponseWriter, r *http.Request) {
		fmt.Fprintf(rw, "Welcome to the home page!")
	})

	handler := drago.New(DemoMiddleware).Handler(mux)

	http.ListenAndServe(":3000", handler)
}

Usage examples

Use

d := drago.New()

d.Use(Middleware1, Middleware2)

handler := d.Handler(http.NewServeMux())

Extend

a := drago.New(Middleware1, Middleware2)
b := drago.New(Middleware3, Middleware4)

a.Extend(b) // a == Middleware1, Middleware2, Middleware3, Middleware4

handler := a.Handler(http.NewServeMux())

HandlerFunc

d := drago.New(Middleware1, Middleware2)

handler := d.HandlerFunc(func(rw http.ResponseWriter, r *http.Request) {
    fmt.Fprintf(rw, "Welcome!")
})
