Fiber是移植NodeJS的Express框架改以Go語言編寫。本套件基於Fasthttp，Fasthttp有不分配記憶體空間和Request Pool的特性，在網路效能方面有著顯著的效能。
## ⚡️ 快速入門
```go
package main
import "github.com/gofiber/fiber"
func main() {
app := fiber.New()
app.Get("/", func(c *fiber.Ctx) {
c.Send("Hello, World 👋!")
})
app.Listen(3000)
}
```
## 🤖 效能

## 💡 理念
不少[Node.js](https://nodejs.org/en/about/)的工程師跳到[Go](https://golang.org/doc/)必須學習一些知識，因此做了一個跟Express一樣的Fiber省這些麻煩。設計還是照原本的**極簡主義**還有遵循**UNIX慣例**，因此新手們可以**無痛**迅速進入Go的世界。
Fiber **受到** 網路上最流行的Web框架ExpressJS**啟發**，結合Express的**易用性**和Go的**高效能**。若你之前用過Node.js寫Web應用(*使用ExpressJS/Koa或類似工具*)，那你已經**上手**了。
有什麼問題請發[issues](https://github.com/gofiber/fiber/issues)或加入Discord [channel](https://gofiber.io/discord)討論，我們想要創造**快速**、**彈性**、**友善**的社群給**任何人**使用！就像Express那樣。
## 👀 範例
以下是一些常見範例。
> 更多程式碼在[範例專案](https://github.com/gofiber/recipes)中或直接看[API文件](https://docs.gofiber.io)。
#### 📖 [**Basic Routing**](https://docs.gofiber.io/#basic-routing)
```go
func main() {
app := fiber.New()
// GET /john
app.Get("/:name", func(c *fiber.Ctx) {
c.Send("Hello, ", c.Params("name"), " 👋!")
// => Hello john 👋!
})
// GET /john/75
app.Get("/:name/:age/:gender?", func(c *fiber.Ctx) {
c.Send(c.Params("name"), " is ", c.Params("age"), " years old 👴")
// => john is 75 years old 👴
})
// GET /dictionary.txt
app.Get("/:file.:ext", func(c *fiber.Ctx) {
c.Send("📃 ", c.Params("file"), ".", c.Params("ext"))
// => 📃 dictionary.txt
})
// GET /flights/LAX-SFO
app.Get("/flights/:from-:to", func(c *fiber.Ctx) {
c.Send("✈ From ", c.Params("from"), ", To: ", c.Params("to"))
// => ✈ From: LAX, To: SFO
})
// GET /api/register
app.Get("/api/*", func(c *fiber.Ctx) {
c.Send("✋ ", c.Params("*"))
// => ✋ /api/register
})
app.Listen(3000)
}
```
#### 📖 [**Serving Static Files**](https://docs.gofiber.io/application#static)
```go
func main() {
app := fiber.New()
app.Static("/", "./public")
// => http://localhost:3000/js/script.js
// => http://localhost:3000/css/style.css
app.Static("/prefix", "./public")
// => http://localhost:3000/prefix/js/script.js
// => http://localhost:3000/prefix/css/style.css
app.Static("*", "/public/index.html")
// => http://localhost:3000/any/path/shows/index/html
app.Listen(3000)
}
```
#### 📖 [**Middleware & Next**](https://docs.gofiber.io/context#next)
```go
func main() {
app := fiber.New()
// Match any route
app.Use(func(c *fiber.Ctx) {
fmt.Println("🥇 First handler")
c.Next()
})
// Match all routes starting with /api
app.Use("/api", func(c *fiber.Ctx) {
fmt.Println("🥈 Second handler")
c.Next()
})
// GET /api/register
app.Get("/api/list", func(c *fiber.Ctx) {
fmt.Println("🥉 Last handler")
c.Send("Hello, World 👋!")
})
app.Listen(3000)
}
```

### 界面引擎
📖 [設定](https://docs.gofiber.io/application#settings)
📖 [引擎](https://github.com/gofiber/template)
📖 [渲染](https://docs.gofiber.io/context#render)
當不指定樣板引擎時Fiber預設用[html/template](https://golang.org/pkg/html/template/)。
如果你想要執行部份或用別的樣板引擎[amber](https://github.com/eknkc/amber)、[handlebars](https://github.com/aymerick/raymond)、[mustache](https://github.com/cbroglie/mustache)、[pug](https://github.com/Joker/jade)之類…請參考符合多樣板引擎的[樣板](https://github.com/gofiber/template)套件。
```go
import (
"github.com/gofiber/fiber"
"github.com/gofiber/template/pug"
)
func main() {
// 你可以在初始化前套用樣板引擎
app := fiber.New(&fiber.Settings{
Views: pug.New("./views", ".pug"),
})
// 或在初始化後任意時間套用:
app.Settings.Views = pug.New("./views", ".pug"),
// 現在，你可以像這樣呼叫樣板 `./views/home.pug`:
app.Get("/", func(c *fiber.Ctx) {
c.Render("home", fiber.Map{
"title": "首頁",
"year": 1999,
})
})
// ...
}
```
### Grouping routes into chains
📖 [Group](https://docs.gofiber.io/application#group)
```go
func main() {
app := fiber.New()
// Root API route
api := app.Group("/api", cors()) // /api
// API v1 routes
v1 := api.Group("/v1", mysql()) // /api/v1
v1.Get("/list", handler) // /api/v1/list
v1.Get("/user", handler) // /api/v1/user
// API v2 routes
v2 := api.Group("/v2", mongodb()) // /api/v2
v2.Get("/list", handler) // /api/v2/list
v2.Get("/user", handler) // /api/v2/user
// ...
}
```
### 中介器logger
📖 [Logger](https://github.com/gofiber/fiber/blob/master/middleware/logger.md)
```go
import (
"github.com/gofiber/fiber"
"github.com/gofiber/fiber/middleware"
)
func main() {
app := fiber.New()
// 預設
app.Use(middleware.Logger())
// 客制格式
app.Use(middleware.Logger("${method} - ${path}"))
// 客制設定
app.Use(middleware.LoggerWithConfig(middleware.LoggerConfig{
Next: func(ctx *fiber.Ctx) bool {
return ctx.Path() != "/private"
},
Format: "${method} - ${path}",
Output: io.Writer,
}))
app.Listen(3000)
}
### 跨網域資源共享 (CORS)
📖 [CORS](https://docs.gofiber.io/middleware#cors)
```go
import (
"github.com/gofiber/fiber"
"github.com/gofiber/cors"
)
func main() {
app := fiber.New()
// 預設的CORS
app.Use(cors.New())
app.Listen(3000)
}
```
在`Origin` header中放網域來檢查CORS:
```bash
curl -H "Origin: http://example.com" --verbose http://localhost:3000
```
### 客制404回應
📖 [HTTP Methods](https://docs.gofiber.io/application#http-methods)
```go
func main() {
app := fiber.New()
app.Static("./public")
app.Get("/demo", func(c *fiber.Ctx) {
c.Send("This is a demo!")
})
app.Post("/register", func(c *fiber.Ctx) {
c.Send("Welcome!")
})
// 用最後一個中介器攔截剩餘的case
app.Use(func(c *fiber.Ctx) {
c.SendStatus(404)
// => 404 "Not Found"
})
app.Listen(3000)
}
```
### JSON 回應
📖 [JSON](https://docs.gofiber.io/context#json)
```go
type User struct {
Name string `json:"name"`
Age int `json:"age"`
}
func main() {
app := fiber.New()
app.Get("/user", func(c *fiber.Ctx) {
c.JSON(&User{"John", 20})
// => {"name":"John", "age":20}
})
app.Get("/json", func(c *fiber.Ctx) {
c.JSON(fiber.Map{
"success": true,
"message": "Hi John!",
})
// => {"success":true, "message":"Hi John!"}
})
app.Listen(3000)
}
```
### WebSocket 升級
📖 [Websocket](https://docs.gofiber.io/middleware#websocket)
```go
import (
"github.com/gofiber/fiber"
"github.com/gofiber/websocket"
)
func main() {
app := fiber.New()
app.Get("/ws", websocket.New(func(c *websocket.Conn) {
for {
mt, msg, err := c.ReadMessage()
if err != nil {
log.Println("read:", err)
break
}
log.Printf("recv: %s", msg)
err = c.WriteMessage(mt, msg)
if err != nil {
log.Println("write:", err)
break
}
}
}))
app.Listen(3000)
// ws://localhost:3000/ws
}
```
### Recover 中介器
📖 [Recover](https://github.com/gofiber/fiber/blob/master/middleware/recover.md)
```go
import (
"github.com/gofiber/fiber"
"github.com/gofiber/fiber/middleware"
)
func main() {
app := fiber.New()
app.Use(middleware.Recover())
app.Get("/", func(c *fiber.Ctx) {
panic("normally this would crash your app")
})
app.Listen(3000)
}
```
