Goa

Goa is under construction, if you are familiar with koa or go and interested in this project, please join us.

What is goa?

goa = go + koa

Just like koa, goa is also not bundled with any middleware. But you can expand functionality to meet your needs at will by middlware. It is flexible, light, high-performance and extensible.

Installation

$ go get -u github.com/goa-go/goa

Hello Goa

func main() {
  app := goa.New()

  app.Use(func(c *goa.Context) {
    c.String("Hello Goa!")
  })
  log.Fatal(app.Listen(":3000"))
}

Middleware

Goa is a web framework based on middleware. Here is an example of using goa-router and logger.

package main

import (
  "fmt"
  "log"
  "time"

  "github.com/goa-go/goa"
  "github.com/goa-go/router"
)

func logger(c *goa.Context) {
  start := time.Now()

  fmt.Printf(
    "[%s] <-- %s %s\n",
    start.Format("2006-01-02 15:04:05"),
    c.Method,
    c.URL,
  )
  c.Next()
  fmt.Printf(
    "[%s] --> %s %s %d %s\n",
    time.Now().Format("2006-01-02 15:04:05"),
    c.Method,
    c.URL,
    time.Since(start).Nanoseconds()/1e6,
    "ms",
  )
}

func main() {
  app := goa.New()
  r := router.New()

  r.GET("/", func(c *goa.Context) {
    c.String("Hello Goa!")
  })

  app.Use(logger)
  app.Use(r.Routes())
  log.Fatal(app.Listen(":3000"))
}

If you are unwilling to use goa-router, you can make a custom router middleware as you like.
