Emmanuel

Emmanuel is a high performance fork of Macaron, a modular web framework in Go.

Getting Started

The minimum requirement of Go is 1.6.

To install Emmanuel:

go get github.com/go-emmanuel/emmanuel

The very basic usage of Emmanuel:

package main

import "github.com/go-emmanuel/emmanuel"

func main() {
	e := emmanuel.Classic()
	e.Get("/", func() string {
		return "Hello world!"
	})
	e.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.

Credits

Changes from Macaron

This framework is a fork of Macaron.

The following are changes made:

  • Use sync.Pool for Context
  • Use Fasthttp (in progress)
  • Other performance tweaks
