Fiber es un framework web inspirado en Express construido sobre Fasthttp, el motor HTTP más rápido para Go. Diseñado para facilitar las cosas y tener un menor tiempo de desarrollo con cero asignación de memoria y pensado para un mejor rendimiento.
## ⚡️ 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://go.dev/doc/) están lidiando con una curva de aprendizaje antes de que puedan comenzar a construir sus aplicaciones web o micro-servicios. 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** .
## ⚠️ Limitantes
* Debido a que Fiber utiliza unsafe, la biblioteca no siempre será compatible con la última versión de Go. Fiber 2.40.0 ha sido probado con las versiones de Go 1.17 a 1.20.
* Fiber no es compatible con interfaces net/http. Esto significa que no lo podrá usar en proyectos como qglgen, go-swagger, u otros que son parte del ecosistema net/http.

### Motores de Vistas
📖 [Configuración](https://docs.gofiber.io/api/fiber#config)
📖 [Motores](https://github.com/gofiber/template)
📖 [Renderizado](https://docs.gofiber.io/api/ctx#render)
El motor por defecto de Fiber, cuando no es especificado, es [html/template](https://pkg.go.dev/html/template/).
Si quiere ejecutar vistas parciales, o usar un motor diferente (como [amber](https://github.com/eknkc/amber), [handlebars](https://github.com/aymerick/raymond), [mustache](https://github.com/cbroglie/mustache) o [pug](https://github.com/Joker/jade), etc).
Revise nuestro paquete para [Plantillas](https://github.com/gofiber/template) que soporta múltiples motores de vistas.
```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/api/app#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
📖 [Logger](https://docs.gofiber.io/api/middleware/logger)

// => 404 "Not Found"
})
log.Fatal(app.Listen(":3000"))
}
```
