Using Cobra to build a CLI accounting app

Developers often utilize command-line interfaces (CLIs) for easy configuration, and Cobra is a popular Go library for building such applications. This tutorial details the creation of a simple accounting CLI application using Cobra, which handles billing, receipt recording, and balance tracking for users, storing data in a JSON file. The guide explores the process of installing Cobra, understanding CLI components like commands and flags, and creating specific commands for credit and debit transactions. The tutorial highlights the importance of keeping the main package lean, using a JSON storage layer for data management, and employing functions to perform transactions and update user balances. By leveraging Cobra, developers can efficiently build CLI apps, as demonstrated by the creation of the "accountant" application, which manages user accounts and transactions with ease.
