Gzip

El middleware Gzip comprime la response HTTP usando el esquema de compresión gzip.

Uso

e.Use(middleware.Gzip())

Configuración personalizada

e := echo.New()
e.Use(middleware.GzipWithConfig(middleware.GzipConfig{
  Level: 5,
}))

Consejo

Pasa un skipper para deshabilitar gzip en ciertas URLs.

e := echo.New()
e.Use(middleware.GzipWithConfig(middleware.GzipConfig{
  Skipper: func(c *echo.Context) bool {
    return strings.Contains(c.Path(), "metrics") // change "metrics" to your own path
  },
}))

Configuración

type GzipConfig struct {
  // Skipper defines a function to skip middleware.
  Skipper Skipper

  // Level is the gzip compression level.
  // Optional. Default value -1.
  Level int

  // MinLength is the length threshold before gzip compression is applied.
  // Optional. Default value 0.
  //
  // Most of the time the default is fine. Compressing a short response might increase
  // the transmitted data because of gzip's format overhead, and compression consumes
  // CPU and time on both server and client. Depending on your use case such a
  // threshold can be useful.
  MinLength int
}
