Exemples et cas d'utilisation

GitHub

Ce guide fournit des exemples pratiques pour les modèles d'application d'horloge courants en utilisant @capgo/capacitor-watch. Le TypeScript côté téléphone fonctionne pour les deux iOS et Android; les exemples de UI d'horloge ci-dessous utilisent SwiftUI (Apple Watch). Réfléchissez les mêmes payloads sur Wear OS avec les chemins de la couche de données de la rubrique de configuration de Wear OS.

Sync workout data between watch and phone.

Envoyez des notifications personnalisées à votre montre.

2. Gérer l'État Hors Ligne

Gérer l'arrêt en ligne avec grâce
async function smartSend(data: any, important: boolean) {
const info = await CapgoWatch.getInfo();
if (info.isReachable) {
// Send immediately
await CapgoWatch.sendMessage({ data });
} else if (important) {
// Queue for later
await CapgoWatch.transferUserInfo({ userInfo: data });
} else {
// Update context (will be available when watch opens app)
await CapgoWatch.updateApplicationContext({ context: data });
}
}
// Bad - sending large objects
connector.sendMessage(["user": fullUserObject])
// Good - send only what's needed
connector.sendMessage([
"userId": user.id,
"name": user.displayName,
"avatarUrl": user.avatarUrl
])
