Fiber is een web framework geïnspireerd door Express gebouwd bovenop Fasthttp, de snelste HTTP-engine voor Go. Ontworpen om snelle ontwikkeling gemakkelijker te maken zonder geheugenallocatie tezamen met hoge prestaties.

⚡️ Bliksemsnelle start

    app := fiber.New()

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

    app.Listen(":3000")
}

💡 Filosofie

Nieuwe gophers die de overstap maken van Node.js naar Go, hebben te maken met een leercurve voordat ze kunnen beginnen met het bouwen van hun webapplicaties of microservices. Fiber, als een web framework, is gebouwd met het idee van minimalisme en volgt de UNIX-manier, zodat nieuwe gophers snel de wereld van Go kunnen betreden met een warm en vertrouwd welkom.\

Fiber is geïnspireerd door Express, het populairste webframework op internet. We hebben het gemak van Express gecombineerd met de onbewerkte prestaties van Go. Als je ooit een webapplicatie in Node.js hebt geïmplementeerd (zoals Express of vergelijkbaar), dan zullen veel methoden en principes heel gewoon voor je lijken.

We luisteren naar onze gebruikers in issues (en overal op het internet) om een snelle, flexibele en vriendelijk Go web framework te maken voor elke taak, deadline en ontwikkelaar vaardigheid! Net zoals Express dat doet in de JavaScript-wereld.

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

    app := fiber.New()

    app.Use(cors.New())

    // ...

}

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")

    })

    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"))
}

        // => {"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 {
