Send

Sets the HTTP response body. The Send body can be of any type.

Send doesn’t append like the Write method. 
  1. c.Send(body ...interface{})
  1. app.Get("/", func(c *fiber.Ctx) {
  2.   c.Send("Hello, World!")         // => "Hello, World!"
  3.   c.Send([]byte("Hello, World!")) // => "Hello, World!"
  4.   c.Send(123)                     // => 123
  5. })

Fiber also provides SendBytes ,SendString and SendStream methods for raw inputs.

Use this if you don’t need type assertion, recommended for faster performance. 
  1. c.SendBytes(b []byte)
  2. c.SendString(s string)
  3. c.SendStream(r io.Reader, s ...int)
  1. app.Get("/", func(c *fiber.Ctx) {
  2.   c.SendByte([]byte("Hello, World!"))
  3.   // => "Hello, World!"
  5.   c.SendString("Hello, World!")
  6.   // => "Hello, World!"
  8.   c.SendStream(bytes.NewReader([]byte("Hello, World!")))
  9.   // => "Hello, World!"
  10. })
