Customer Enrollment System

This is a simple customer enrollment system implemented in TypeScript using the Inquirer library for CLI interaction and file system (FS) module for data persistence.

Features

• Enroll a customer with their details including first name, last name, gender, age, and mobile number.
• Set an initial credit amount for the customer's bank account.
• View customer information, including their account balance.
• Data is saved to a JSON file for persistent storage.

Getting Started

1. Clone this repository or download the source code.
2. Navigate to the project directory in your terminal.
3. Install dependencies using npm install.

Usage

Run the program using the command:

tsc myBank.ts && node myBank.js

Follow the prompts to enroll a customer and provide the necessary information, including their initial credit amount.

Functionality

• The program defines an IBankAccount interface with debit and credit methods, which the BankAccount class implements.
• The Customer class represents a customer with properties such as first name, last name, gender, age, mobile number, and a bank account.
• The enrollCustomer function guides the user through enrolling a customer and initializing their bank account.
• The loadCustomerData function reads customer data from the 'customers.json' file.
• The saveCustomerData function saves customer data to the 'customers.json' file.
• The main function provides a menu for enrolling customers or exiting the program.

Data Persistence

Customer data is stored in a 'customers.json' file in the project directory. When a new customer is enrolled, their data is added to the file.

Error Handling

The program includes basic error handling to catch exceptions and display meaningful error messages to the user.

Dependencies

inquirer: Used for user input and interaction.

fs: Used for file system operations.
