🚀 Fiber v1.8. What's new, updated and re-thinked?

Introduction

Hi, Fiber community! 👋 With a little delay, but let me introduce the new major version of Fiber Go web framework – v1.8.

💭 Please note: official Fiber docs may not contains extensive description for some changes. Don't worry, authors are working right now for it.

📝 Table of contents

New life of Middlewares

A willful decision was made and now... all Fiber middlewares are put in their own Go package middleware with huge improvements!

If you want to install/update Fiber with middlewares, run command:

go get -u github.com/gofiber/fiber/...
Enter fullscreen mode Exit fullscreen mode

And use it on import section (after main package):

// ...

import (
    "github.com/gofiber/fiber"
    "github.com/gofiber/fiber/middleware" // add middleware package to project
)

// ...
Enter fullscreen mode Exit fullscreen mode

OK. Let's see what comes out of it! 😉

✅ middleware.BasicAuth()

Provides a very simple (but useful sometimes) authentication:

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

    // Set middleware config
    config := middleware.BasicAuthConfig{
        Users: fiber.Map{
            "john":  "doe",
            "admin": "123456",
        },
    }

    // Using BasicAuth middleware with config
    app.Use(middleware.BasicAuth(config))

    // Route for success authenticate
    app.Get("/", func(c *fiber.Ctx) {
        c.Send("You are authorized!")
    })

    app.Listen(3000)
}
Enter fullscreen mode Exit fullscreen mode

Check, how it works on console (by curl):

curl --user john:doe http://localhost:3000
Enter fullscreen mode Exit fullscreen mode

✅ middleware.CORS()

CORS middleware implements Cross-Origin Resource Sharing specification. It's extremely useful middleware for work with frontend, when you build REST API.

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

    // Using CORS middleware
    app.Use(middleware.CORS())

    // ...
}
Enter fullscreen mode Exit fullscreen mode

And now, run on console:

curl -H "Origin: http://example.com" --verbose http://localhost:3000
Enter fullscreen mode Exit fullscreen mode

✅ middleware.Limiter()

This middleware can limit repeated requests to public APIs and/or endpoints. For example, let's limit the number of requests to a maximum of 2 per 10 seconds:

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

    // Max 2 requests per 10 seconds
    config := middleware.LimiterConfig{
        Timeout: 10,
        Max:     2,
    }

    // Using Limiter middleware with config
    app.Use(middleware.Limiter(config))

    // ...
}
Enter fullscreen mode Exit fullscreen mode

✅ middleware.Logger()

Built-in middleware for logs the information about each HTTP request.

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

    // If you want to change default Logger config
    config := middleware.LoggerConfig{
      Format:     "${time} - ${method} ${path}\n",
      TimeFormat: "Mon, 2 Jan 2006 15:04:05 MST",
    }

    // Using Logger middleware with config
    app.Use(middleware.Logger(config))

    // ...
}
Enter fullscreen mode Exit fullscreen mode

✅ middleware.RequestID()

This middleware ca add an identifier to the request using X-Request-ID header:

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

    // Using RequestID middleware
    app.Use(middleware.RequestID())

    // ...
}
Enter fullscreen mode Exit fullscreen mode

It generates and sets X-Request-ID header with UUID like:

6ba7b810-9dad-11d1-80b4-00c04fd430c8
Enter fullscreen mode Exit fullscreen mode

✅ middleware.Helmet()

Helmet middleware provides protection against:

  • Cross-Site Scripting (XSS) attack.
  • Content type sniffing.
  • Clickjacking.
  • Insecure connection.
  • And other code injection attacks.
func main() {
    app := fiber.New()

    // Using Helmet middleware
    app.Use(middleware.Helmet())

    // ...
}
Enter fullscreen mode Exit fullscreen mode

Fiber updates

New, Updated & Re-thinked

New features, some updates and re-thinks functions for you 👇

✅ Range() method for Ctx

This struct contain the type and a slice of ranges will be returned:

// Range: bytes=500-700, 700-900

app.Get("/", func(c *fiber.Ctx) {
  b := c.Range(1000)

  if b.Type == "bytes" {
    for r := range r.Ranges {
      fmt.Println(r)
      // => [500, 700]
    }
  }
})
Enter fullscreen mode Exit fullscreen mode

✅ Compress() method for Ctx

With this method you can easily enable/disable compression within handlers.

func main() {
    // Init app and set config
    app := fiber.New(&fiber.Settings{
      Compression: true, // enable global compression
    })

    // Route with compression
    app.Get("/compressed", func(c *fiber.Ctx) {
      c.Send("Hello, compressed World!") // compressed
    })

    // Route without compression
    app.Get("/not-compressed", func(c *fiber.Ctx) {
      c.Compress(false)                      // disable compression
      c.Send("Hello, not compressed World!") // not compressed
    })

    // ...
}
Enter fullscreen mode Exit fullscreen mode

ℹ️ Compression option for Settings

Enables GZip or Deflate compression for all responses:

app.Settings.Compression = true
Enter fullscreen mode Exit fullscreen mode

ℹ️ Immutable option for Settings

When enabled, all values returned by context methods are immutable:

app.Settings.Immutable = true
Enter fullscreen mode Exit fullscreen mode

By default, they are valid until you return from the handler.

Re-named list

🔁 Settings.ViewFolder -> Settings.TemplateFolder
🔁 Settings.ViewEngine -> Settings.TemplateEngine
🔁 Settings.ViewExtension -> Settings.TemplateExtension

Can you share an example CRUD API with MySQL and Fiber? Can't find anything online :(

Hi! 👋 Thx for interesting Fiber.

I'm planning my next article's series like "Create REST API with Fiber and PostgreSQL". Maybe I will add some notes about working with MySQL to there.

Stay tuned! 😉

Nice! I've already started working on a side project with same stack. I am new to go. Have experience in express. Fiber is a life saver for developers like myself who is looking forward to learn something new. Cheers!

Hi! Maybe you could include a JWT example after basic auth. Thank you

Hello! Yep, good point, thx.

We're preparing example for using JWT in our repo: github.com/gofiber/jwt (coming soon).
