Fiber是一个基于Express的 Web框架，建立在Go语言写的 最快的FasthttpHTTP引擎的基础上。皆在简化 零内存分配和提高性能，以便快速开发。
## ⚡️ 快速入门
```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)
}
```
## 🤖 性能

## 💡 哲学
从[Node.js](https://nodejs.org/en/about/)切换到[Go的](https://golang.org/doc/)新gopher在开始构建Web应用程序或微服务之前正在应对学习过程。 Fiber作为一个**Web框架** ，是按照**极简主义**的思想并遵循**UNIX方式创建的**，因此新的gopher可以以热烈和可信赖的欢迎**方式**迅速进入Go的世界。
Fiber **受** Internet上最流行的Web框架Expressjs的**启发** 。我们结合了Express的**易用**性和Go的**原始性能** 。如果您曾经在Node.js上实现过Web应用程序(*使用Express.js或类似工具*)，那么许多方法和原理对您来说似乎**非常易懂**。

### 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
import (
"github.com/gofiber/fiber"
"github.com/gofiber/template/pug"
)
func main() {
// You can setup Views engine before initiation app:
app := fiber.New(&fiber.Settings{
Views: pug.New("./views", ".pug"),
})
// OR after initiation app at any convenient location:
app.Settings.Views = pug.New("./views", ".pug"),
// And now, you can call template `./views/home.pug` 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://github.com/gofiber/fiber/blob/master/middleware/logger.md)
```go
import (
"github.com/gofiber/fiber"
"github.com/gofiber/fiber/middleware"
)
func main() {
app := fiber.New()
// Default
app.Use(middleware.Logger())
// Custom logging format
app.Use(middleware.Logger("${method} - ${path}"))
// Custom Config
app.Use(middleware.LoggerWithConfig(middleware.LoggerConfig{
Next: func(ctx *fiber.Ctx) bool {
return ctx.Path() != "/private"
},
Format: "${method} - ${path}",
Output: io.Writer,
}))
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://github.com/gofiber/fiber/blob/master/middleware/recover.md)
```go
import (
"github.com/gofiber/fiber"
"github.com/gofiber/fiber/middleware"
)
func main() {
app := fiber.New()
app.Use(middleware.Recover())
app.Get("/", func(c *fiber.Ctx) {
panic("normally this would crash your app")
})
app.Listen(3000)
}
```
