# Fiber      **[Fiber](https://github.com/gofiber/fiber)** is an **[Express](https://expressjs.com/en/4x/api.html)** styled HTTP framework implementation running on **[Fasthttp](https://github.com/valyala/fasthttp)**, the **fastest** HTTP engine for **[Go](https://golang.org/doc/)**. The package make use of similar framework convention as they are in express. People switching from **[Node](https://nodejs.org/en/about/)** to **[Go](https://golang.org/doc/)** often end up in a bad learning curve to start building their webapps, this project is meant to **ease** things up for **fast** development, but with **zero memory allocation** and **performance** in mind. See **[API Documentation](https://gofiber.github.io/fiber/)** [](https://gofiber.github.io/fiber/#/benchmarks) ## Features * Optimized for speed and low memory usage. * Rapid Server-Side Programming * Easy routing with parameters * Static files with custom prefix * Middleware with Next support * Express API endpoints * **[API Documentation](https://gofiber.github.io/fiber/)** ## Installing Assuming you’ve already installed **[Go](https://golang.org/doc/)**, install the **[Fiber](https://github.com/gofiber/fiber)** package by calling the following command: ```bash $ go get -u github.com/gofiber/fiber ``` ## Hello world Embedded below is essentially the simplest Fiber app you can create. ```bash $ create server.go ``` ```go package main import "github.com/gofiber/fiber" func main() { app := fiber.New() app.Get("/", func(c *fiber.Ctx) { c.Send("Hello, World!") }) app.Listen(8080) } ``` ```bash $ go run server.go ``` Browse to **http://localhost:8080** and you should see `Hello, World!` on the page. ## Static files To serve static files, use the [Static](https://gofiber.github.io/fiber/#/?id=static-files) method. ```go package main import "github.com/gofiber/fiber" func main() { app := fiber.New() app.Static("./public") app.Listen(8080) } ``` Now, you can load the files that are in the public directory: ```shell http://localhost:8080/hello.html http://localhost:8080/js/jquery.js http://localhost:8080/css/style.css ``` ## Middleware Middleware has never been so easy, just like express you call the Next() matching route function! ```go package main import "github.com/gofiber/fiber" func main() { app := fiber.New() app.Get("/", func(c *fiber.Ctx) { c.Set("random-header", "random-value") c.Write("1st route!\n") c.Next() }) app.Get("/", func(c *fiber.Ctx) { c.Write("2nd route!\n") c.Next() }) app.Get("/", func(c *fiber.Ctx) { c.Write("3rd route!\n") }) app.Listen(8080) } ``` ## API Documentation We created an extended API documentation including examples, **[click here](https://gofiber.github.io/fiber/)** ## License gofiber/fiber is free and open-source software licensed under the [MIT License](https://github.com/gofiber/fiber/edit/master/LICENSE). *Caught a mistake?
