fiber/.github/README_de.md

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("Hello, World 👋!")
    })

    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 ein Web-Framework, wurde erschaffen mit der Idee von Minimalismus und folgt dem UNIX Weg damit neue Gophers mit einem herzlichen und vertrauenswürdigen Willkommen schnell in die Welt von Go eintreten können.

Fiber ist inspiriert von Expressjs, 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.

👀 Beispiele

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

Listed below are some of the common examples. If you want to see more code examples , please visit our Recipes repository or visit our hosted API documentation.

📖 Basic Routing

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

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

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

    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"))
}

Cross-Origin Resource Sharing (CORS)

📖 CORS

import (
    "log"

    app := fiber.New()

    app.Use(cors.New())

    // ...

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

Check CORS by passing any domain in Origin header:

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

Custom 404 response

📖 HTTP Methods

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

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

        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 Response

📖 JSON

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

        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)
