Booking-App-CLI

The Go CLI (Command-Line Interface) Ticket Generator is a robust and efficient application designed to streamline the process of booking and managing event tickets. This tool provides an easy-to-use interface for users to input their details and receive their event tickets promptly via email.

Key Feature

1. User Input Collection:

Name: Collects the full name of the user.

• Email: Gathers the user's email address to send the ticket.
• Number of Tickets: Captures the quantity of tickets the user wants to purchase.
• Event Date: Records the date of the event for which the tickets are being booked.

2. Unique Ticket ID Generation:

Each ticket is assigned a unique identifier to ensure proper tracking and validation.

• Ticket Creation: The application processes the inputs to generate a digital ticket containing all the necessary details, including the unique ticket ID.

3. Email Notification:

Automated Email Sending: Once the ticket is generated, the application automatically sends an email to the provided address. This email contains the ticket with all relevant details and the unique ticket ID

Technical Overview:

• Programming Language: The application is built using Go, known for its simplicity, performance, and concurrency capabilities, making it ideal for handling input/output operations and email notifications efficiently.
• Input Handling: Utilizes Go’s flag package to parse command-line arguments, ensuring a seamless user experience.
• Unique ID Generation: Implements a UUID generation library to create unique ticket identifiers.
• Email Sending: Integrates with an SMTP library to handle email delivery, ensuring the tickets reach the users promptly and reliably.
