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"
func main() {
app := fiber.New()
app.Get("/", func(c *fiber.Ctx) {
c.Send("Hello, World!")
})
app.Listen(3000)
}
```
## ⚙️ Instalación
En primer lugar, [descargue](https://golang.org/dl/) e instale Go. Se requiere `1.11` o superior.
La instalación se realiza con el comando [`go get`](https://golang.org/cmd/go/#hdr-Add_dependencies_to_current_module_and_install_them) :
```bash
go get github.com/gofiber/fiber/...
```

## 💡 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) .
### Routing
📖 https://docs.gofiber.io/#basic-routing
```go
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)
}
```
### Serve 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")
// => http://localhost:3000/any/path/shows/index/html
app.Listen(3000)
}
```
### Middleware & Next
📖 https://docs.gofiber.io/routing#middleware
📖 https://docs.gofiber.io/context#next
```go
func main() {
app := fiber.New()
// Match any route
app.Use(func(c *fiber.Ctx) {
fmt.Println("First middleware")
c.Next()
})
// Match all routes starting with /api
app.Use("/api", func(c *fiber.Ctx) {
fmt.Println("Second middleware")
c.Next()
})
// GET /api/register
app.Get("/api/list", func(c *fiber.Ctx) {
fmt.Println("Last middleware")
c.Send("Hello, World!")
})
app.Listen(3000)
}
```

### Template engines
📖 https://docs.gofiber.io/application#settings
📖 https://docs.gofiber.io/context#render
📖 https://docs.gofiber.io/middleware#template
Fiber supports the default [Go template engine](https://golang.org/pkg/html/template/)
But if you want to use another template 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).
You can use our [Template Middleware](https://docs.gofiber.io/middleware#template).
```go
package main
import (
"github.com/gofiber/fiber"
"github.com/gofiber/template"
)
func main() {
// You can setup template engine before initiation app:
app := fiber.New(&fiber.Settings{
TemplateEngine: template.Mustache(),
TemplateFolder: "./views",
TemplateExtension: ".tmpl",
})
// OR after initiation app at any convenient location:
app.Settings.TemplateEngine = template.Mustache()
app.Settings.TemplateFolder = "./views"
app.Settings.TemplateExtension = ".tmpl"
// And now, you can call template `./views/home.tmpl` like this:
app.Get("/", func(c *fiber.Ctx) {
c.Render("home", fiber.Map{
"title": "Homepage",
"year": 1999,
})
})
// ...
}
```
### Grouping routes into chains
📖 https://docs.gofiber.io/application#group
```go
func main() {
app := fiber.New()
// Root API route
api := app.Group("/api", cors()) // /api
// API v1 routes
v1 := api.Group("/v1", mysql()) // /api/v1
v1.Get("/list", handler) // /api/v1/list
v1.Get("/user", handler) // /api/v1/user
// API v2 routes
v2 := api.Group("/v2", mongodb()) // /api/v2
v2.Get("/list", handler) // /api/v2/list
v2.Get("/user", handler) // /api/v2/user
// ...
}
```
### Middleware logger
📖 https://docs.gofiber.io/middleware#logger
```go
import (
"github.com/gofiber/fiber"
"github.com/gofiber/logger"
)
func main() {
app := fiber.New()
// Optional logger config
config := logger.Config{
Format: "${time} - ${method} ${path}\n",
TimeFormat: "Mon, 2 Jan 2006 15:04:05 MST",
}
// Logger with config
app.Use(logger.New(config))
app.Listen(3000)
}
```
### Cross-Origin Resource Sharing (CORS)
📖 https://docs.gofiber.io/middleware#cors
```go
import (
"github.com/gofiber/fiber"
"github.com/gofiber/cors"
)
func main() {
app := fiber.New()
// CORS with default config
app.Use(cors.New())
app.Listen(3000)
}
```
Check CORS by passing any domain in `Origin` header:
```bash
curl -H "Origin: http://example.com" --verbose http://localhost:3000
```
### Custom 404 response
📖 https://docs.gofiber.io/application#http-methods
```go
func main() {
app := fiber.New()
app.Static("/public")
app.Get("/demo", func(c *fiber.Ctx) {
c.Send("This is a demo!")
})
app.Post("/register", func(c *fiber.Ctx) {
c.Send("Welcome!")
})
// Last middleware to match anything
app.Use(func(c *fiber.Ctx) {
c.SendStatus(404)
// => 404 "Not Found"
})
app.Listen(3000)
}
```
### JSON Response
📖 https://docs.gofiber.io/context#json
```go
type User struct {
Name string `json:"name"`
Age int `json:"age"`
}
func main() {
app := fiber.New()
app.Get("/user", func(c *fiber.Ctx) {
c.JSON(&User{"John", 20})
// => {"name":"John", "age":20}
})
app.Get("/json", func(c *fiber.Ctx) {
c.JSON(fiber.Map{
"success": true,
"message": "Hi John!",
})
// => {"success":true, "message":"Hi John!"}
})
app.Listen(3000)
}
```
### WebSocket Upgrade
📖 https://docs.gofiber.io/middleware#websocket
```go
import (
"github.com/gofiber/fiber"
"github.com/gofiber/websocket"
)
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
}
}
}))
app.Listen(3000)
// ws://localhost:3000/ws
}
```
### Recover middleware
📖 https://docs.gofiber.io/middleware#recover
```go
import (
"github.com/gofiber/fiber"
"github.com/gofiber/recover"
)
func main() {
app := fiber.New()
// Optional recover config
config := recover.Config{
Handler: func(c *fiber.Ctx, err error) {
c.SendString(err.Error())
c.SendStatus(500)
},
}
// Logger with custom config
app.Use(recover.New(config))
app.Listen(3000)
}
```
