Fiber — is an Express.js inspired web framework build on Fasthttp 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() {
// Create new Fiber instance
app := fiber.New()
// Create new route with GET method
app.Get("/", func(c *fiber.Ctx) {
c.Write("Hello, World!")
})
// Start server on http://localhost:3000
app.Listen(3000)
}First of all, download and install Go.
Go
1.11(with enabled Go Modules) 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

People switching from Node.js to Go having a heard time on how to 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, but with a warm welcome.
Fiber is inspired by the Express framework, 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 Fiber community Cookbook repository or API documentation.
// ...
app := fiber.New()
