Michael Aboagye, a backend software and security engineer in Ghana, presents a tutorial on building a simple diary web application using the Flask framework and Couchbase as the backend server. The guide covers the installation and configuration of the necessary components, including Flask, Jinja templates, and Couchbase Server, and emphasizes the use of Docker to run Couchbase Server. It details the creation of a virtual environment, the installation of required packages, and the setup of Couchbase Server, including the configuration of clusters and buckets. The tutorial also provides code snippets for creating server-side routes to handle user data submission and retrieval, and guides users through setting up HTML templates for the application's user interface. The project can be cloned from GitHub, offering a practical introduction to integrating Flask with Couchbase for secure backend service development.
