📘 Taskflow CLI (Go • Fully Type-Safe)

🧠 Overview

Taskflow is a lightweight CLI todo manager built in Go. It follows a clean architecture:

CLI (cmd) → Service → Repository → JSON storage

Each command flows through these layers, keeping responsibilities separated and easy to maintain.

A sample solution for the Task Tracker CLI challenge from roadmap.sh.

This project demonstrates a fully type-safe command-line application built in Go, capable of managing tasks (add, update, delete, mark status, and list) with persistent JSON storage.

Challenge: https://roadmap.sh/projects/task-tracker
