FIberは、Expressに触発されたWebフレームワークです。Go 最速のHTTPエンジンであるFasthttpで作られています。ゼロメモリアロケーションとパフォーマンスを念頭に置いて設計されており、迅速な開発をサポートします。
## ⚡️ クイックスタート
```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)
}
```
## ⚙️ インストール
まず、Goを[ダウンロード](https://golang.org/dl/)してください。 `1.11`以降が必要です。
そして、[`go get`](https://golang.org/cmd/go/#hdr-Add_dependencies_to_current_module_and_install_them)コマンドを使用してインストールしてください。
```bash
go get -u github.com/gofiber/fiber/...
```

## 💡 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。

以下に一般的な例をいくつか示します。他のコード例をご覧になりたい場合は、 [Recipesリポジトリ](https://github.com/gofiber/recipes)または[APIドキュメント](https://docs.gofiber.io)にアクセスしてください。
### Routing
📖 [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
📖 [Static](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
📖 [Middleware](https://docs.gofiber.io/routing#middleware)
📖 [Next](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
📖 [Settings](https://docs.gofiber.io/application#settings)
📖 [Render](https://docs.gofiber.io/context#render)
📖 [Template](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
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
📖 [Group](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
📖 [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)
📖 [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
📖 [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) {
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
📖 [JSON](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
📖 [Websocket](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
📖 [Recover](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)
}
```
