Ejemplos y casos de uso
Copia un prompt de configuración con los pasos de instalación y la guía completa en markdown para este plugin.
Esta guía ofrece ejemplos prácticos de patrones comunes para apps de watch usando @capgo/capacitor-watch. El TypeScript del teléfono funciona tanto para iOS y Android; los siguientes ejemplos de UI del reloj usan SwiftUI (Apple Watch). Replica los mismos payloads en Wear OS con las rutas del Data Layer de la guía de configuración de Wear OS.

Sección titulada “Buenas prácticas”1. Elige el método de transferencia adecuado
Sección titulada “1. Elige el método de transferencia adecuado”| Método | Caso de uso | Entrega |
|---|---|---|
sendMessage | Interactivo, sensible al tiempo | Inmediato (falla si no hay conexión) |
updateApplicationContext | Estado actual de la app | Solo el último valor |
transferUserInfo | Datos importantes | En cola, garantizado |
