Fiber is an Express inspired web framework built on top of Fasthttp, the fastest HTTP engine for Go. Designed to ease things up for fast development with zero memory allocation and performance in mind.

⚡️ Quickstart

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")
}

�� Philosophy

New gophers that make the switch from Node.js to Go are dealing with a learning curve before they can start building their web applications or microservices. Fiber, as a web framework, was created with the idea of minimalism and follows the UNIX way, so that new gophers can quickly enter the world of Go with a warm and trusted welcome.

Fiber is inspired by Express, the most popular web framework on the Internet. We combined the ease of Express and raw performance of Go. If you have ever implemented a web application in Node.js (using Express or similar), then many methods and principles will seem very common to you.

We listen to our users in issues, Discord channel and all over the Internet to create a fast, flexible and friendly Go web framework for any task, deadline and developer skill! Just like Express does in the JavaScript world.

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.

�� Examples

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 /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"))
}

�� 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/list
    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"

    })

    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 {
        log.Println("write:", err)

什么是fiber Fiber 是一个执行单元。 fiber是react16 对核心算法的依次重写，fiber会使原本同步的渲染过程变成异步的。同步渲染的递归调用栈是非常深的，且是漫长而不可打断的更新过程。因此将会带来很大的风险：同步渲染一旦开始将会牢牢的抓住主线程不放，直到递归完成。这段时间浏览器无法处理任何渲染之外的事情，会进入一种无法处理用户交互的状态 Fiber 是一种数据结构，支撑 Fi
