Macaron Build Status

Macaron Logo

Package macaron is a high productive and modular web framework in Go.

Current version: 1.0.0

Getting Started

The minimum requirement of Go is 1.3.

To install Macaron:

go get gopkg.in/macaron.v1

The very basic usage of Macaron:

package main

import "gopkg.in/macaron.v1"

func main() {
	m := macaron.Classic()
	m.Get("/", func() string {
		return "Hello world!"
	})
	m.Run()
}

Features

  • Powerful routing with suburl.
  • Flexible routes combinations.
  • Unlimited nested group routers.
  • Directly integrate with existing services.
  • Dynamically change template files at runtime.
  • Allow to use in-memory template and static files.
  • Easy to plugin/unplugin features with modular design.
  • Handy dependency injection powered by inject.
  • Better router layer and less reflection make faster speed.

Middlewares

Middlewares allow you easily plugin/unplugin features for your Macaron applications.

There are already many middlewares to simplify your work:

  • render - Go template engine
  • static - Serves static files
  • gzip - Gzip compression to all responses
  • binding - Request data binding and validation
  • i18n - Internationalization and Localization
  • cache - Cache manager
  • session - Session manager
  • csrf - Generates and validates csrf tokens
  • captcha - Captcha service
  • pongo2 - Pongo2 template engine support
  • sockets - WebSockets channels binding
  • bindata - Embed binary data as static and template files
  • toolbox - Health check, pprof, profile and statistic services
  • oauth2 - OAuth 2.0 backend
  • switcher - Multiple-site support
  • method - HTTP method override
  • permissions2 - Cookies, users and permissions
  • renders - Beego-like render engine(Macaron has built-in template engine, this is another option)
