The post serves as an introduction to the technical architecture of a demo project involving a web application and a mobile/IoT application, both utilizing Couchbase technologies. The web application employs a typical setup with a Vue.js client and a Node.js server, which handles REST endpoints and communication with Couchbase Server, while incorporating Server Sent Events and Couchbase Eventing Service to push data to clients efficiently. On the mobile/IoT front, a Texas Instruments NFC patch is used to capture temperature data, which is stored in the Couchbase Lite database on a mobile app and synced via Couchbase Sync Gateway to the cloud. The post highlights the ease of schema changes and data synchronization, driven by the Couchbase ecosystem, and invites readers to explore further through a demo video, Couchbase Connect conferences, and various online resources.
