Building an Interactive Terminal Application with Go & Dragonfly

In this article, Annu Singh shares her experience in building a terminal application using Go and Dragonfly. The application features an engaging user interface with a colorful Kanban board for personal task management. It allows adding, editing, and deleting tasks interactively from the terminal, updates task status with a single button press, persists data to Dragonfly, and lists tasks according to their approaching deadlines using a sorted-set data structure. The application's state is stored in models (an interface type in Go) and updated based on user commands via the model's Update method. The BubbleTea framework creates event-driven TUI apps that can listen to user inputs and respond to them accordingly, making them interactive. To render tasks on a priority basis according to their deadlines, Dragonfly's sorted-set is used to store and retrieve tasks.
