Course Manager CLI

A simple, interactive command-line application for managing your courses with persistent JSON storage.

✨ Features

• Add Courses - Interactive prompts to add new courses with title and price
• Persistent Storage - Courses are saved to courses.json
• Interactive CLI - User-friendly command-line interface
• Auto-reload - Development mode with Nodemon for quick iteration

🚀 Quick Start

Prerequisites

• Node.js (v14 or higher)
• npm (comes with Node.js)

Installation

npm install

Running the Application

npm run index

This will start the Course Manager CLI with auto-reload enabled.

📝 Usage

Once the application is running, use the following commands:

Add a Course

add
# or use the alias
a

You'll be prompted to enter:

• Course Title: Name of the course
• Course Price: Price as a number

The course will be saved to courses.json.

Example Session

$ npm run index
> nodemon index

📦 Project Structure

CLI/
├── index.js           # Main CLI application
├── courses.json       # Course data storage (auto-generated)
├── package.json       # Project dependencies and scripts
└── README.md          # This file

🛠️ Dependencies

• commander (v14.0.3) - CLI framework for command parsing
• inquirer (v13.3.2) - Interactive command-line prompts
• nodemon (v3.1.14, dev) - Auto-reload during development

🔧 npm Scripts

| Script | Purpose | |--------|---------| | npm run index | Run the app with Nodemon (development) | | npm test | Test runner (not yet configured) |

📊 Data Format

Courses are stored in courses.json as a JSON array:

[
  {
    "title": "JavaScript Basics",
    "price": 49.99
  },
  {
    "title": "React Advanced",
    "price": 79.99
  }
]

💡 How It Works

1. Commander parses CLI commands and options
2. Inquirer displays interactive prompts for user input
3. Node.js fs module handles file operations (read/write)
4. JSON stores and retrieves course data persistently

🎯 Future Enhancements

• View all courses
• Delete a course
• Update course information
• Filter courses by price range
• Export to CSV
• Database integration
