Fiber is an Expressjs inspired web framework build 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.
package main
import "github.com/gofiber/fiber"
func main() {
app := fiber.New()
app.Get("/", func(c *fiber.Ctx) {
c.Send("Hello, World!")
})
app.Listen(3000)
}First of all, download and install Go. 1.11 or higher is required.
Installation is done using the go get command:
go get github.com/gofiber/fiberThese tests are performed by TechEmpower and Go Web. If you want to see all results, please visit our Wiki.
- Robust routing
- Serve static files
- Extreme performance
- Low memory footprint
- Express API endpoints
- Middleware & Next support
- Rapid server-side programming

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 follow UNIX way, so that new gophers can quickly enter the world of Go with a warm and trusted welcome.
Fiber is inspired by the Expressjs, the most popular web framework on Internet. We combined the ease of Express and raw performance of Go. If you have ever implemented a web application on Node.js (using Express.js or similar), then many methods and principles will seem very common to you.
Listed below are some of the common examples. If you want to see more code examples, please visit our Recipes repository or visit our API documentation.
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.Listen(3000)
}func main() {
app := fiber.New()
// GET /john
app.Get("/:name", func(c *fiber.Ctx) {
fmt.Printf("Hello %s!", c.Params("name"))
// => Hello john!
})
// GET /john
app.Get("/:name/:age?", func(c *fiber.Ctx) {
fmt.Printf("Name: %s, Age: %s", c.Params("name"), c.Params("age"))
// => Name: john, Age:
})
// GET /api/register
app.Get("/api*", func(c *fiber.Ctx) {
fmt.Printf("/api%s", c.Params("*"))
// => /api/register
})
app.Listen(3000)
}func main() {
app := fiber.New()
// Match any post route
app.Post(func(c *fiber.Ctx) {
user, pass, ok := c.BasicAuth()
if !ok || user != "john" || pass != "doe" {
c.Status(403).Send("Sorry John")
return
}
c.Next()
})
// Match all routes starting with /api
app.Use("/api", func(c *fiber.Ctx) {
c.Set("Access-Control-Allow-Origin", "*")
c.Set("Access-Control-Allow-Headers", "X-Requested-With")
c.Next()
})
// Optional param
app.Post("/api/register", func(c *fiber.Ctx) {
username := c.Body("username")
password := c.Body("password")
// ..
})
app.Listen(3000)
}func main() {
app := fiber.New()
// Serve static files from "public" directory
app.Static("./public")
// Last middleware
app.Use(func (c *fiber.Ctx) {
c.SendStatus(404) // => 404 "Not Found"
})
app.Listen(3000)
}func main() {
app := fiber.New()
type User struct {
Name string `json:"name"`
Age int `json:"age"`
}
// Serialize JSON
app.Get("/json", func (c *fiber.Ctx) {
c.JSON(&User{"John", 20})
})
app.Listen(3000)
