Gzip

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

Todo el middleware principal reside en el paquete middleware:

import "github.com/labstack/echo/v5/middleware"

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
  },
}))

Campos del código fuente

Campo	Tipo	Descripción	Fuente
Skipper	Skipper	Skipper defines a function to skip middleware.	L27
Level	int	Gzip compression level. Optional. Default value -1.	L31
MinLength	int	Length threshold before gzip compression is applied. Optional. Default value 0. Most of the time you will not need to change the default. Compressing a short response might increase the transmitted data because of the gzip format overhead. Compressing the response will also consume CPU and time on the server and the client (for decompressing). Depending on your use case such a threshold might be useful.
