## 💡 哲学
[Node.js](https://nodejs.org/en/about/)から[Go](https://golang.org/doc/) に乗り換えようとしている新しいGopherはWebフレームワークやマイクロサービスの構築を始める前に多くを学ばなければなりません。
しかし、 **Webフレームワーク**であるFiberは**ミニマリズム**と**UNIX哲学**をもとに作られているため、新しいGopherはスムーズにGoの世界に入ることができます。
Fiberは人気の高いWebフレームワークであるExpressjsに**インスパイア**されています。
わたしたちは Expressの**手軽さ**とGoの**パフォーマンス**を組み合わせました。
もしも、WebアプリケーションをExpress等のNode.jsフレームワークで実装した経験があれば、多くの方法や原理がとても**馴染み深い**でしょう。

### Views engines
📖 [Settings](https://docs.gofiber.io/application#settings)
📖 [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"))
}
```
### Grouping routes into chains
📖 [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
📖 [Logger](https://github.com/gofiber/fiber/blob/master/middleware/logger.md)
```go
package main

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

app := fiber.New()
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
```
### Custom 404 response
📖 [HTTP Methods](https://docs.gofiber.io/application#http-methods)
```go
func main() {
app := fiber.New()
app.Static("/", "./public")
app.Get("/demo", func(c *fiber.Ctx) error {
return c.SendString("This is a demo!")
})
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"))
}
```

"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
}
```
