The new Eventing service in Couchbase Server allows developers to write JavaScript functions that respond to documents getting created, updated, or deleted, and can execute a curl function to make requests to HTTP endpoints. A proof of concept example was created using Functions (part of Eventing) to send a text message when a customer's ticket is scanned at the gate. The example uses Twilio for sending text messages and demonstrates how to create a concierge service that assigns VIP customers to specific concierges and notifies them via text message when a new ticket scan document is created or modified. The function reads documents from a bucket, gets the Twilio credentials, constructs a message, and sends it using the curl construct, which is still in development and intended for development purposes only. The service can be used to create a system that scans tickets at the gate and notifies VIP customers' concierges via text message.
