🧾 Task Tracker (Built with Go)

Task Tracker is a simple, zero-dependency command-line application to help you manage your daily tasks efficiently. Built in Go, it stores your tasks locally in a JSON file and allows you to add, update, delete, and track statuses like todo, in-progress, and done — all from your terminal.

🚀 Features

• ✅ Add new tasks with descriptions
• ✏️ Update task descriptions
• ❌ Delete tasks
• 🔄 Mark tasks as in-progress or done
• 📋 List all tasks or filter by status: todo, in-progress, done
• 📁 Stores tasks persistently in a local tasks.json file
• 🧱 No external libraries or frameworks used — just the Go standard library

📦 Installation

1. Make sure you have Go installed: Install Go
2. Clone the repository:

git clone https://github.com/yash27007/task-tracker.git

🛠 Usage

The CLI uses positional arguments to perform different operations.

➕ Add a Task

./task-cli add "Buy groceries"
# Output: Task added successfully (ID: 1)

✏️ Update a Task

./task-cli update 1 "Buy groceries and cook dinner"
# Output: Task updated successfully

❌ Delete a Task

./task-cli delete 1
# Output: Task deleted successfully

🔄 Mark as In-Progress

./task-cli mark-in-progress 1
# Output: Task marked as in-progress

✅ Mark as Done

./task-cli mark-done 1
# Output: Task marked as done

📋 List All Tasks

./task-cli list

📌 List Tasks by Status

./task-cli list todo
./task-cli list in-progress
./task-cli list done

📂 Task Structure

Each task is stored in tasks.json and has the following structure:

{
  "id": 1,
  "description": "Buy groceries",
  "status": "todo",
  "createdAt": "2025-05-15T14:34:00Z",
  "updatedAt": "2025-05-15T14:34:00Z"
}

---

📁 File Storage

• All tasks are stored in a JSON file named tasks.json in the current working directory.
• The file is automatically created if it does not exist.

---

⚙️ Error Handling

• Gracefully handles invalid commands, missing files, incorrect IDs, and malformed inputs.
• Provides user-friendly error messages and status updates.

🧪 Example Workflow

./task-cli add "Write documentation"
./task-cli add "Fix bug #102"
./task-cli list

./task-cli delete 1
