What is pomodoro-timer?

Pomodoro Timer CLI is a terminal-based countdown tool built with TypeScript that runs entirely in your command line. The Pomodoro technique is a time management method where you work in focused blocks (typically 25 minutes) separated by short breaks, and this tool provides a simple timer to facilitate that. You start the timer by running it with a minute and second count as arguments. While counting down, the tool updates a single line in the terminal displaying the remaining time alongside a visual progress bar that shrinks as time elapses. It uses in-place terminal updates rather than printing a new line every second, so the output stays clean. The project is explicitly designed as a TypeScript learning exercise rather than a polished productivity product. The README walks through the programming concepts demonstrated by the codebase: using command-line arguments to accept input, converting between time formats, managing state that changes over time using an interval timer, and rendering dynamic visual output in a terminal by overwriting the current line. The modular code structure is intended to show how to break a problem into small, testable pieces. It runs on Node.js and is written in TypeScript. You start it via npm start followed by a number of minutes and seconds. The timer has second-level accuracy.
