Task Tracker CLI

A simple command-line task manager built in Go.

Task Tracker allows you to track and manage your tasks directly from the terminal. You can add, update, delete, and manage tasks stored in a JSON file.

This project helps practice:

• Working with the filesystem
• Handling CLI arguments
• Structs and JSON encoding/decoding
• Project structure in Go
• Error handling
• Writing modular code

Features

• Add tasks
• Update tasks
• Delete tasks
• Store tasks in tasks.json
• UUID-based task IDs
• Simple CLI interface

Usage

Run the app using:

./run.sh add "Buy milk"
./run.sh update <id> "New description"
./run.sh delete <id>



bash

go build -o task
./task add "Buy milk"

How It Works

Tasks are stored in tasks.json. Each task has:

    UUID ID

    Description

    Completion status

    CreatedAt timestamp

    UpdatedAt timestamp

The CLI reads user input using os.Args. Tasks are loaded, modified, then saved back to JSON.
Example Task Format (JSON)
json

[
  {
    "id": "c4f1c2e8-8a8e-4e9a-9e0e-6b9b8a7c1d3f",
    "description": "Buy milk",
    "completed": false,
    "created_at": "2026-02-16T10:00:00Z",
    "updated_at": "2026-02-16T10:00:00Z"
  }
]

Future Improvements
