Here's a neutral and interesting summary of the text: Developing an application that requires storing files in a NoSQL database like Couchbase can be beneficial, especially when storage space is limited or replication features are desired to prevent data loss. To achieve this, we need to set up Couchbase Server with a primary index using the Couchbase Query (CBQ) Client, and then configure a basic Node.js application that accepts file uploads, converts them into base64 strings, and stores these strings in Couchbase along with necessary metadata. The application uses Express.js for routing, Multer for handling file uploads, and N1QL queries to interact with the Couchbase database. By using this approach, we can efficiently store and manage files in a scalable and secure manner.
