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

package main

import "github.com/gofiber/fiber/v2"

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

    app.Get("/", func(c *fiber.Ctx) error {
        return c.SendString("Hello, World 👋!")
    })

    app.Listen(":3000")
}

🤖 效能

💡 理念

不少Node.js的工程師跳到Go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或加入 Discord channel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。

⚠️ Limitations

Due to Fiber's usage of unsafe, the library may not always be compatible with the latest Go version. Fiber 2.18.0 has been tested with Go versions 1.14 to 1.17.
Fiber is not compatible with net/http interfaces. This means you will not be able to use projects like gqlgen, go-swagger, or any others which are part of the net/http ecosystem.

👀 範例

以下是一些常見範例。

更多程式碼在範例專案中或直接看API 文件。

📖 Basic Routing

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

    // GET /api/register
    app.Get("/api/*", func(c *fiber.Ctx) error {
        msg := fmt.Sprintf("✋ %s", c.Params("*"))
        return c.SendString(msg) // => ✋ register
    })

    // GET /flights/LAX-SFO
    app.Get("/flights/:from-:to", func(c *fiber.Ctx) error {
        msg := fmt.Sprintf("💸 From: %s, To: %s", c.Params("from"), c.Params("to"))
        return c.SendString(msg) // => 💸 From: LAX, To: SFO
    })

    // GET /dictionary.txt
    app.Get("/:file.:ext", func(c *fiber.Ctx) error {
        msg := fmt.Sprintf("📃 %s.%s", c.Params("file"), c.Params("ext"))
        return c.SendString(msg) // => 📃 dictionary.txt
    })

    // GET /john/75
    app.Get("/:name/:age/:gender?", func(c *fiber.Ctx) error {
        msg := fmt.Sprintf("👴 %s is %s years old", c.Params("name"), c.Params("age"))
        return c.SendString(msg) // => 👴 john is 75 years old
    })

    // GET /john
    app.Get("/:name", func(c *fiber.Ctx) error {
        msg := fmt.Sprintf("Hello, %s 👋!", c.Params("name"))
        return c.SendString(msg) // => Hello john 👋!
    })

    log.Fatal(app.Listen(":3000"))
}

📖 Route Naming

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

    // GET /api/register
    app.Get("/api/*", func(c *fiber.Ctx) error {
        msg := fmt.Sprintf("✋ %s", c.Params("*"))
        return c.SendString(msg) // => ✋ register
    }).Name("api")

    data, _ := json.MarshalIndent(app.GetRoute("api"), "", "  ")
    fmt.Print(string(data))
    // Prints:
    // {
    //    "method": "GET",
    //    "name": "api",
    //    "path": "/api/*",
    //    "params": [
    //      "*1"
    //    ]
    // }


    log.Fatal(app.Listen(":3000"))
}

📖 Serving Static Files

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

    log.Fatal(app.Listen(":3000"))
}

界面引擎

📖 設定 📖 引擎 📖 渲染

當不指定樣板引擎時 Fiber 預設用html/template。

如果你想要執行部份或用別的樣板引擎amber、handlebars、mustache、pug之類…請參考符合多樣板引擎的樣板套件。

package main

import (
    "github.com/gofiber/fiber/v2"
    "github.com/gofiber/template/pug"
)

func main() {
    // You can setup Views engine before initiation app:
    app := fiber.New(fiber.Config{
        Views: pug.New("./views", ".pug"),
    })

    // And now, you can call template `./views/home.pug` like this:
    app.Get("/", func(c *fiber.Ctx) error {
        return c.Render("home", fiber.Map{
            "title": "Homepage",
            "year":  1999,
        })
    })

    log.Fatal(app.Listen(":3000"))
}

Grouping routes into chains

📖 Group

func middleware(c *fiber.Ctx) error {
    fmt.Println("Don't mind me!")
    return c.Next()
}

func handler(c *fiber.Ctx) error {
    return c.SendString(c.Path())
}

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

    // Root API route
    api := app.Group("/api", middleware) // /api

    // API v1 routes
    v1 := api.Group("/v1", middleware) // /api/v1
    v1.Get("/list", handler)           // /api/v1/list
    v1.Get("/user", handler)           // /api/v1/user

    // API v2 routes
    v2 := api.Group("/v2", middleware) // /api/v2
    v2.Get("/list", handler)           // /api/v2/list
    v2.Get("/user", handler)           // /api/v2/user

    // ...
}

中介器 logger

📖 Logger

package main

import (
    "log"

    "github.com/gofiber/fiber/v2"
    "github.com/gofiber/fiber/v2/middleware/logger"
)

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

    app.Use(logger.New())

    // ...

    log.Fatal(app.Listen(":3000"))
}

跨網域資源共享 (CORS)

📖 CORS

import (
    "log"

    "github.com/gofiber/fiber/v2"
    "github.com/gofiber/fiber/v2/middleware/cors"
)

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

    app.Use(cors.New())

    // ...

    log.Fatal(app.Listen(":3000"))
}

在Origin header 中放網域來檢查 CORS:

curl -H "Origin: http://example.com" --verbose http://localhost:3000

客制 404 回應

📖 HTTP Methods

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

    app.Static("/", "./public")

    app.Get("/demo", func(c *fiber.Ctx) error {
        return c.SendString("This is a demo!")
    })

    app.Post("/register", func(c *fiber.Ctx) error {
        return c.SendString("Welcome!")
    })

    // Last middleware to match anything
    app.Use(func(c *fiber.Ctx) error {
        return c.SendStatus(404)
        // => 404 "Not Found"
    })

    log.Fatal(app.Listen(":3000"))
}

JSON 回應

📖 JSON

type User struct {
    Name string `json:"name"`
    Age  int    `json:"age"`
}

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

    app.Get("/user", func(c *fiber.Ctx) error {
        return c.JSON(&User{"John", 20})
        // => {"name":"John", "age":20}
    })

    app.Get("/json", func(c *fiber.Ctx) error {
        return c.JSON(fiber.Map{
            "success": true,
            "message": "Hi John!",
        })
        // => {"success":true, "message":"Hi John!"}
    })

    log.Fatal(app.Listen(":3000"))
}

WebSocket 升級

📖 Websocket

import (
    "github.com/gofiber/fiber/v2"
    "github.com/gofiber/fiber/v2/middleware/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
      }
    }
  }))

  log.Fatal(app.Listen(":3000"))
  // ws://localhost:3000/ws
}

Recover 中介器

📖 Recover

import (
	"github.com/gofiber/fiber/v2"
	"github.com/gofiber/fiber/recover"
)

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

	app.Use(recover.New())

	app.Get("/", func(c *fiber.Ctx) error {
		panic("normally this would crash your app")
	})

	log.Fatal(app.Listen(":3000"))
}
