Overview

Package echo implements a fast and unfancy HTTP server framework for Go (Golang).

Example: 

package main

import (
  "net/http"

  "github.com/labstack/echo"
  "github.com/labstack/echo/middleware"
)

// Handler
func hello(c echo.Context) error {
  return c.String(http.StatusOK, "Hello, World!")
}

func main() {
  // Echo instance
  e := echo.New()

  // Middleware
  e.Use(middleware.Logger())
  e.Use(middleware.Recover())

  // Routes
  e.GET("/", hello)

  // Start server
  e.Logger.Fatal(e.Start(":1323"))
}
