## Cliente WebSockets { #websockets-client }

### En producción { #in-production }

En tu sistema de producción, probablemente tengas un frontend creado con un framework moderno como React, Vue.js o Angular.

Y para comunicarte usando WebSockets con tu backend probablemente usarías las utilidades de tu frontend.
