Goa is under construction, if you are familiar with [koa](https://github.com/koajs/koa) or go and interested in this project, please join us.

## What is goa?

goa = go + [koa](https://github.com/koajs/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

```bash

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

```

##  Hello Goa

```go

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.

```go

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.
