ACE

Blazing fast Go Web Framework

Installation

go get github.com/plimble/ace

Import

import "github.com/plimble/ace"

Performance

Ace is very fast you can see on this

Usage

Quick Start

a := ace.New()
a.GET("/:name", func(c *ace.C) {
	name := c.Param("name")
	c.JSON(200, map[string]string{"hello": name})
})
a.Run(":8080")

Default Middleware (Logger, Recovery)

a := ace.Default()
a.GET("/", func(c *ace.C) {
	c.String(200,"Hello ACE")
})
a.Run(":8080")

Router

a.DELETE("/", HandlerFunc)
a.HEAD("/", HandlerFunc)
a.OPTIONS("/", HandlerFunc)
a.PATCH("/", HandlerFunc)
a.PUT("/", HandlerFunc)
a.POST("/", HandlerFunc)
a.GET("/", HandlerFunc)

a := ace.New()

a.GET("/", func(c *ace.C){
	c.String(200, "Hello world")
})

a.POST("/form/:id/:name", func(c *ace.C){
	id := c.Param("id")
	name := c.Param("name")
	age := c.Request.PostFormValue("age")
})

Response

data := struct{
	Name string `json:"name"`
}{
	Name: "John Doe",
}
c.JSON(200, data)

c.String(200, "Hello Ace")

//application/octet-stream
c.Download(200, []byte("Hello Ace"))

c.HTML("index.html")

c.Redirect("/home")

Group Router

g := a.Group("/people", func(c *ace.C) {
	fmt.Println("before route func")
	c.Next()
})

// /people/:name
g.GET("/:name", func(c *ace.C) {
	c.JSON(200, map[string]string{"TEST": "GET METHOD"})
})

// /people/:name
g.POST("/:name", func(c *ace.C) {
	c.JSON(200, map[string]string{"TEST": "POST METHOD"})
})

Data

Set/Get data in any HandlerFunc

a.Use(func(c *ace.C){
	c.SetData("isLogin", true)
})

a.Get("/", func(c *ace.C){
	isLogin := c.GetData("isLogin").(bool)
	//or get all data
	//c.GetAllData()
})

Get Post Form and Query

a.Get("/", func(c *ace.C){
	name := c.MustPostString(key, default_value)
	age := c.MustPostInt(key, d)

	q := c.MustQueryString(key, default_value)
	score := c.MustQueryFloat64(key, default_value)
})

Get data From JSON Request

a.Get("/", func(c *ace.C){
	user := struct{
		Name string `json:"name"`
	}{}

	c.ParseJSON(&user)
})

Panic Response

Use panic instead of if err != nil for response error

a.Get("/save", func(c *ace.C){
	user := &User{}

	c.ParseJSON(user)

	//this func return error
	//if error go to panic handler
	c.Panic(doSomething1(user))
	c.Panic(doSomething2(user))

	c.String(201, "created")
}

a.Get("/get", func(c *ace.C){
	id := c.Param("id")

	user, err := doSomeThing()
	//if error go to panic handler
	c.Panic(err)

	c.JSON(200, user)
}

Custom panic response

a := ace.New()
a.Panic(func(c *ace.C, rcv interface{}){
	switch err := rcv.(type) {
		case error:
			c.String(500, "%s\n%s", err, ace.Stack())
		case CustomError:
			log.Printf("%s\n%s", err, ace.Stack())
			c.JSON(err.Code, err.Msg)
	}
})

Middlewares

Ace middleware is implemented by custom handler

type HandlerFunc func(c *C)

a := ace.New()
a.Use(ace.Logger())

Built-in Middlewares

a.Static("/assets", "./img")

You can use store from sessions

import github.com/plimble/sessions/store/cookie

a := ace.New()

store := cookie.NewCookieStore()
a.Use(ace.Session(store, nil))

a.GET("/", func(c *ace.C) {
	//get session name
	session1 := c.Sessions("test")
	session1.Set("test1", "123")
	session1.Set("test2", 123)

	session2 := c.Sessions("foo")
	session2.Set("baz1", "123")
	session2.Set("baz2", 123)

	c.String(200, "")
})

a.GET("/test", func(c *C) {
	session := c.Sessions("test")
	//get value from key test1 if not found default value ""
	test1 := session.GetString("test1", "")
	test2 := session.GetInt("test2", 0)

	c.String(200, "")
})

a.Use(ace.Logger())

HTML Template Engine

Ace built on renderer interface. So you can use any template engine

type Renderer interface {
	Render(w http.ResponseWriter, name string, data interface{})
}
