# Examples

#### Multiple File Upload
```go

package main

import "github.com/fenny/fiber"

func main() {
  // lol
  app := fiber.New()
  app.Post("/", func(c *fiber.Ctx) {
    // Parse the multipart form
    if form := c.MultipartForm(); form != nil {
      // => *multipart.Form

      // Get all files from "documents" key
      files := form.File["documents"]
      // => []*multipart.FileHeader

      // Loop trough files
      for _, file := range files {
        fmt.Println(file.Filename, file.Size, file.Header["Content-Type"][0])
        // => "tutorial.pdf" 360641 "application/pdf"

        // Save the files to disk
        c.SaveFile(file, fmt.Sprintf("./%s", file.Filename))
      }
    }
  })
  app.Listen(8080)
}
```
#### 404 Handling
```go
package main

import "github.com/fenny/fiber"

func main() {
  app := fiber.New()

  app.Get("./static")
  app.Get(notFound)

  app.Listen(8080)
}

func notFound(c *fiber.Ctx) {
  c.Status(404).Send("Not Found")
}
```
#### Static Caching
```go
package main

import "github.com/fenny/fiber"

func main() {
  app := fiber.New()
  app.Get(cacheControl)
  app.Get("./static")
  app.Listen(8080)
}

func cacheControl(c *fiber.Ctx) {
  c.Set("Cache-Control", "max-age=2592000, public")
  c.Next()
}
```
#### Enable CORS
```go
package main

import "./fiber"

func main() {
  app := fiber.New()

  app.All("/api", enableCors)
  app.Get("/api", apiHandler)

  app.Listen(8080)
}

func enableCors(c *fiber.Ctx) {
  c.Set("Access-Control-Allow-Origin", "*")
  c.Set("Access-Control-Allow-Headers", "X-Requested-With")
  c.Next()
}
func apiHandler(c *fiber.Ctx) {
  c.Send("Hi, I'm API!")
}
```
#### Returning JSON
```go
package main

import "./fiber"

type Data struct {
  Name string
  Age  int
}

func main() {
  app := fiber.New()
  app.Get("/json", func(c *fiber.Ctx) {
    data := SomeData{
      Name: "John",
      Age:  20,
    }
    c.Json(data)
    // or
    err := c.Json(data)
    if err != nil {
      c.Send("Something went wrong!")
    }
  })
  app.Listen(8080)
}
```
