The blog post outlines the author's journey in developing a Node.js application using Couchbase as the database, detailing the process over a series of posts. Initially, it covers the installation of the Couchbase Node SDK, noting that Windows users receive pre-built components while others may need additional tools like node-gyp. The post explains three methods to input data into Couchbase—insert, replace, and upsert—and focuses on creating a simple demo using the upsert method. The author describes setting up the environment with Express.js, body-parser, and a local Couchbase Server, and details the steps to connect to the Couchbase cluster and create a basic form to capture and handle data input. The process includes setting up routes to manage form submissions, converting the submitted data to JSON, and storing it in a Couchbase document. The author hints at future posts that will explore building a more functional application and structuring data representation in Couchbase.
