Crypto-Coindex

This project is a Node.js CLI tool for checking cryptocurrency prices. It utilizes various Node.js packages and the CoinAPI to provide real-time cryptocurrency data.

Description

• Modules Used: The modules used in the project are commander for handling CLI commands, inquirer for user input prompts, config store for configuration management, axios for API requests, and colors for CLI output styling.

• Command Functionality: Organized command functionality into separate files and folders for maintainability and modularity.

• API Key Handling: Implemented a "key manager" class to handle set, get, and delete operations for API keys using config store.

• User Input Validation: Utilized inquirer for prompting the user for an API key and implemented custom validation to ensure the key is not empty.

• Error Handling: Implemented error handling for scenarios such as missing API keys or API request failures.
