Fiber é um framework web inspirado no Express, construído sobre o Fasthttp, o motor HTTP mais rápido do Go. Projetado para facilitar e acelerar o desenvolvimento, com zero de alocação de memória e desempenho em mente.
## ⚡️ Início 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")
}
```
## 🤖 Benchmarks
Esses testes são realizados pelo [TechEmpower](https://www.techempower.com/benchmarks/#section=data-r19&hw=ph&test=plaintext) e [Go Web](https://github.com/smallnest/go-web-framework-benchmark). Se você quiser ver todos os resultados, visite nosso [Wiki](https://docs.gofiber.io/benchmarks) .
## ⚙️ Instalação
Primeiro de tudo, faça o [download](https://golang.org/dl/) e instale o Go. É necessário a versão `1.14` ou superior.
A instalação é feita usando o comando [`go get`](https://golang.org/cmd/go/#hdr-Add_dependencies_to_current_module_and_install_them) :
```bash
go get github.com/gofiber/fiber/v2/...

## 💡 Filosofia
Os novos gophers que mudaram do [Node.js](https://nodejs.org/en/about/) para o [Go](https://golang.org/doc/) estão tendo que lidar com uma curva de aprendizado antes que possam começar a criar seus aplicativos web ou microsserviços. O Fiber, como um **framework web**, foi criado com a ideia de ser **minimalista** e seguindo a **filosofia UNIX**, para que novos gophers possam, rapidamente, entrar no mundo do Go com uma recepção calorosa e confiável.
O Fiber é **inspirado** no Express, o framework web mais popular da Internet. Combinamos a **facilidade** do Express e com o **desempenho bruto** do Go. Se você já implementou um aplicativo web com Node.js ( _usando Express.js ou similar_ ), então muitos métodos e princípios parecerão **muito familiares** para você.
## 👀 Exemplos
Listados abaixo estão alguns exemplos comuns. Se você quiser ver mais exemplos de código,

a [documentação da API](https://docs.gofiber.io).
#### 📖 [**Roteamento básico**](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
})
// GET /api/register
app.Get("/api/*", func(c *fiber.Ctx) error {
msg := fmt.Sprintf("✋ %s", c.Params("*"))
return c.SendString(msg) // => ✋ register
})
log.Fatal(app.Listen(":3000"))
}
```
#### 📖 [**Servindo arquivos estáticos**](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
log.Fatal(app.Listen(":3000"))
}
```
#### 📖 [**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 {
fmt.Println("🥈 Second handler")
return c.Next()
})
// GET /api/register
app.Get("/api/list", func(c *fiber.Ctx) error {

### Engines de visualização
📖 [Config](https://docs.gofiber.io/fiber#config)
📖 [Engines](https://github.com/gofiber/template)
📖 [Render](https://docs.gofiber.io/context#render)
O Fiber usa por padrão o [html/template](https://golang.org/pkg/html/template/) quando nenhuma engine é selecionada.
Se você quiser uma execução parcial ou usar uma engine diferente como [amber](https://github.com/eknkc/amber), [handlebars](https://github.com/aymerick/raymond), [mustache](https://github.com/cbroglie/mustache) ou [pug](https://github.com/Joker/jade) etc.. Dê uma olhada no package [Template](https://github.com/gofiber/template) que suporta multiplas engines de visualização.
```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"))
}
```
### Agrupamento de rotas
📖 [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(cors.New())
// ...
log.Fatal(app.Listen(":3000"))
}
```
Verifique o CORS passando qualquer domínio no header `Origin`:
```bash
curl -H "Origin: http://example.com" --verbose http://localhost:3000
```

// Last middleware to match anything
app.Use(func(c *fiber.Ctx) error {
return c.SendStatus(404)
// => 404 "Not Found"
})
log.Fatal(app.Listen(":3000"))
}
```

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
}
}
}))
