## 💡 Philosophy

New gophers that make the switch from [Node.js](https://nodejs.org/en/about/) to [Go](https://golang.org/doc/) are dealing with a learning curve before they can start building their web applications or microservices. Fiber, as a **web framework**, was created with the idea of **minimalism** and follows the **UNIX way**, so that new gophers can quickly enter the world of Go with a warm and trusted welcome.

Fiber is **inspired** by Express, the most popular web framework on the Internet. We combined the **ease** of Express and **raw performance** of Go. If you have ever implemented a web application in Node.js (_using Express or similar_), then many methods and principles will seem **very common** to you.

We **listen** to our users in [issues](https://github.com/gofiber/fiber/issues), Discord [channel](https://gofiber.io/discord) _and all over the Internet_ to create a **fast**, **flexible** and **friendly** Go web framework for **any** task, **deadline** and developer **skill**! Just like Express does in the JavaScript world.

## 👀 Examples

Listed below are some of the common examples. 

> If you want to see more code examples, please visit our [Recipes repository](https://github.com/gofiber/recipes) or visit our [API documentation](https://docs.gofiber.io).

### 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)
}
```
