The blog post discusses how to utilize the cURL function within the Couchbase Eventing service to make requests to a remote service, bypassing the need for N1QL, in a development environment. It starts by highlighting the developer preview status of the Eventing service and the changes expected in Couchbase Server 6.5. The post outlines the process of creating a simple Node.js API using Express and BodyParser, serving as a mock endpoint to receive and return data. The tutorial then guides readers to develop a basic Couchbase Function with cURL support, which triggers upon document creation or modification, sending data to the Node.js application. The example emphasizes the experimental nature of the feature, recommending it for development purposes only, and invites readers to explore more about Couchbase Eventing through its Developer Portal.
