EventBridge esempi che utilizzano SDK for JavaScript (v3)

Importa i moduli SDK e client e chiama ilAPI.

Mostra come creare un evento EventBridge pianificato da Amazon che richiami una AWS Lambda funzione. Configura EventBridge per utilizzare un'espressione cron per pianificare quando viene richiamata la funzione Lambda. In questo esempio, si crea una funzione Lambda utilizzando il runtime Lambda. JavaScript API Questo esempio richiama diversi AWS servizi per eseguire un caso d'uso specifico. Questo esempio dimostra come creare un'app che invia un messaggio di testo via mobile ai tuoi dipendenti che si congratula con loro alla data dell'anniversario di un anno.

Questo esempio è anche disponibile nella Guida per lo sviluppatore di AWS SDK for JavaScript v3 .
