Fiber ist ein von Expressjs inspiriertes Web-Framework, aufgebaut auf Fasthttp - die schnellste HTTP engine für Go. Kreiert, um Dinge zu vereinfachen, für schnelle Entwicklung mit keinen Speicherzuweisungen und Performance im Hinterkopf.

⚡️ Schnellstart

package main

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

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

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

    app.Listen(":3000")
}

💡 Philosophie

Neue Gopher, welche von Node.js zu Go umsteigen, müssen eine Lernkurve durchlaufen, bevor sie ihre Webanwendungen oder Microservices erstellen können. Fiber als Web-Framework, wurde mit der Idee von Minimalismus erschaffen und folgt dem UNIX Weg, damit neue Gophers mit einem herzlichen und vertrauenswürdigen Willkommen schnell in der Welt von Go durchstarten können.

Fiber ist inspiriert von Express.js, dem beliebtesten Web-Framework im Internet. Wir haben die Leichtigkeit von Express und die Rohleistung von Go kombiniert. Wenn du jemals eine Webanwendung mit Node.js implementiert hast (mit Express.js oder ähnlichem), werden dir viele Methoden und Prinzipien sehr vertraut vorkommen.

⚠️ 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.

👀 Beispiele

Nachfolgend sind einige der gängigsten Beispiele aufgeführt. Wenn du weitere Codebeispiele sehen möchtest, besuche bitte unser "Recipes Repository" oder besuche unsere API Dokumentation.

📖 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"))
}

📖 Middleware & Next

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

	// Match any route
	app.Use(func(c *fiber.Ctx) error {
		fmt.Println("🥇 First handler")
		return c.Next()
	})

	// Match all routes starting with /api
	app.Use("/api", func(c *fiber.Ctx) error {
		fmt.Println("🥈 Second handler")
		return c.Next()
	})

	// GET /api/register
	app.Get("/api/list", func(c *fiber.Ctx) error {
		fmt.Println("🥉 Last handler")
		return c.SendString("Hello, World 👋!")
	})

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

Views engines

📖 Config 📖 Engines 📖 Render

Fiber defaults to the html/template when no view engine is set.

If you want to execute partials or use a different engine like amber, handlebars, mustache or pug etc..

Checkout our Template package that support multiple view engines.

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

    // ...
}

Middleware 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"))
}

    })

    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"))
}

        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 Upgrade

📖 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)
