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)
Example
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
JSON
data := struct{
Name string `json:"name"`
}{
Name: "John Doe",
}
c.JSON(200, data)
String
c.String(200, "Hello Ace")
Download
//application/octet-stream
c.Download(200, []byte("Hello Ace"))
HTML
c.HTML("index.html")
Redirect
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)
Example
a := ace.New()
a.Use(ace.Logger())
Built-in Middlewares
Serve Static
a.Static("/assets", "./img")
Session
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, "")
})
Logger
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{})
}
