💡 Philosophy

from Node.js Switch to Go Your new gopher needs to Go through a learning process before you start building Web applications or microservices. As a Web framework, Fiber is created according to the minimalist idea and UNIX way, so the new gopher can quickly enter the Go world in a warm and reliable welcome.

Fiber is inspired by Express, the most popular Web framework on the Internet. We combine the ease of use of Express with the raw performance of Go. If you have ever been in node JS (using Express or similar tools), many methods and principles should be very easy for you to understand.

We focus on the whole Internet users in issues And Discord channel In order to create a fast, flexible and friendly Go web framework that meets any task, deadline and developer skills. Just like Express in the JavaScript world.

limit

• Because fiber uses the unsafe feature, it may be incompatible with the latest Go version. Fiber 2.18.0 has been verified on Go 1.14 to 1.17.
• Fiber is incompatible with the net/http interface. This means that you cannot use gqlen, go swagger, or any other project that belongs to the net/http ecosystem.

👀 Example

Some common examples are listed below. If you want to see more code examples, please visit our Recipes Code base or 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"))
}

📖 Static file service

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 and 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"))
}
