Fiber es un framework web inspirado en Express construido sobre Fasthttp, el motor HTTP más rápido para Go. Diseñado para facilitar las cosas para un desarrollo rápido con cero asignación de memoria y rendimiento en mente.
## ⚡️ Inicio rápido
```go
package main
import "github.com/gofiber/fiber/v2"
func main() {
app := fiber.New()
app.Get("/", func(c *fiber.Ctx) error {
return c.SendString("Hello, World 👋!")
})
app.Listen(":3000")
}
```

## 💡 Filosofía
Los nuevos gophers que hacen el cambio de [Node.js](https://nodejs.org/en/about/) a [Go](https://golang.org/doc/) están lidiando con una curva de aprendizaje antes de que puedan comenzar a construir sus aplicaciones web o microservicios. Fiber, como un **marco web** , fue creado con la idea del **minimalismo** y sigue el **camino de UNIX** , para que los nuevos gophers puedan ingresar rápidamente al mundo de Go con una cálida y confiable bienvenida.
Fiber está **inspirado** en Expressjs, el framework web más popular en Internet. Combinamos la **facilidad** de Express y **el rendimiento bruto** de Go. Si alguna vez ha implementado una aplicación web en Node.js ( _utilizando Express.js o similar_ ), muchos métodos y principios le parecerán **muy comunes** .
## 👀 Ejemplos
A continuación se enumeran algunos de los ejemplos comunes. Si desea ver más ejemplos de código, visite nuestro [repositorio de Recetas](https://github.com/gofiber/recipes) o nuestra [documentación de API](https://docs.gofiber.io) .
#### 📖 [**Basic Routing**](https://docs.gofiber.io/#basic-routing)
```go
func main() {
app := fiber.New()
// GET /john
app.Get("/:name", func(c *fiber.Ctx) error {
msg := fmt.Sprintf("Hello, %s 👋!", c.Params("name"))
return c.SendString(msg) // => Hello john 👋!
})
// 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 /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 /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

app.Get("/api/*", func(c *fiber.Ctx) error {
msg := fmt.Sprintf("✋ %s", c.Params("*"))
return c.SendString(msg) // => ✋ register
})
log.Fatal(app.Listen(":3000"))
}
```
#### 📖 [**Serving Static Files**](https://docs.gofiber.io/application#static)
```go
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")

```
#### 📖 [**Middleware & Next**](https://docs.gofiber.io/context#next)
```go
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 {

### Views engines
📖 [Config](https://docs.gofiber.io/fiber#config)
📖 [Engines](https://github.com/gofiber/template)
📖 [Render](https://docs.gofiber.io/context#render)
Fiber defaults to the [html/template](https://golang.org/pkg/html/template/) when no view engine is set.
If you want to execute partials or use a different engine like [amber](https://github.com/eknkc/amber), [handlebars](https://github.com/aymerick/raymond), [mustache](https://github.com/cbroglie/mustache) or [pug](https://github.com/Joker/jade) etc..
Checkout our [Template](https://github.com/gofiber/template) package that support multiple view engines.
```go
package main
import (
"github.com/gofiber/fiber/v2"
"github.com/gofiber/template/pug"
)
func main() {
// You can setup Views engine before initiation app:
app := fiber.New(fiber.Config{
Views: pug.New("./views", ".pug"),
})
// And now, you can call template `./views/home.pug` like this:
app.Get("/", func(c *fiber.Ctx) error {
return c.Render("home", fiber.Map{
"title": "Homepage",
"year": 1999,
})
})
log.Fatal(app.Listen(":3000"))
}
```
### Agrupando rutas en cadenas
📖 [Group](https://docs.gofiber.io/application#group)
```go
func middleware(c *fiber.Ctx) error {
fmt.Println("Don't mind me!")
return c.Next()
}
func handler(c *fiber.Ctx) error {
return c.SendString(c.Path())
}
func main() {
app := fiber.New()
// Root API route
api := app.Group("/api", middleware) // /api
// API v1 routes
v1 := api.Group("/v1", middleware) // /api/v1
v1.Get("/list", handler) // /api/v1/list
v1.Get("/user", handler) // /api/v1/user
// API v2 routes
v2 := api.Group("/v2", middleware) // /api/v2
v2.Get("/list", handler) // /api/v2/list
v2.Get("/user", handler) // /api/v2/user
// ...
}
```
### Middleware logger

app.Use(logger.New())
// ...
log.Fatal(app.Listen(":3000"))
}

app.Use(cors.New())
// ...
log.Fatal(app.Listen(":3000"))
}
```
Check CORS by passing any domain in `Origin` header:
```bash
curl -H "Origin: http://example.com" --verbose http://localhost:3000
```
### Respuesta 404 personalizada
📖 [HTTP Methods](https://docs.gofiber.io/application#http-methods)
```go
func main() {

})
app.Post("/register", func(c *fiber.Ctx) error {
return c.SendString("Welcome!")
})
// Last middleware to match anything
app.Use(func(c *fiber.Ctx) error {
return c.SendStatus(404)
// => 404 "Not Found"
})
log.Fatal(app.Listen(":3000"))
}
```
### Respuesta JSON
📖 [JSON](https://docs.gofiber.io/ctx#json)

"message": "Hi John!",
})
// => {"success":true, "message":"Hi John!"}
})
log.Fatal(app.Listen(":3000"))
}
```

)
func main() {
app := fiber.New()
app.Get("/ws", websocket.New(func(c *websocket.Conn) {
for {
mt, msg, err := c.ReadMessage()
if err != nil {
log.Println("read:", err)
break
}
log.Printf("recv: %s", msg)
err = c.WriteMessage(mt, msg)
if err != nil {
log.Println("write:", err)
break
}
}
}))
log.Fatal(app.Listen(":3000"))
// ws://localhost:3000/ws
}
```
### Recover middleware
