About a month ago, the author wrote about developing RESTful APIs for web applications using Node.js and the Hapi.js framework, with a focus on integrating NoSQL databases like Couchbase Server. Hapi.js is highlighted as a user-friendly framework for creating web APIs efficiently. To enhance the tutorial, the author created a video demonstrating the integration of Couchbase Server into a Node.js application, showcasing the creation of API endpoints with data validation for communication with the NoSQL database. For further details on using Couchbase with Node.js, the author recommends checking the Couchbase Developer Portal.
