GoTicket

GoTicket is a streamlined e-commerce web application designed for buying and selling tickets. The application leverages a microservices architecture, with distinct services for authentication, orders, tickets, expiration, and payments. Each service operates within its own container, managed by Kubernetes.

The backend is developed using Node.js and Express.js, both written in TypeScript, and utilizes MongoDB for data storage. The frontend is crafted with React.js and Next.js, ensuring a responsive and dynamic user experience.

Features

• Users can list tickets for events, making them available for purchase by other users.
• When a user initiates a ticket purchase, the ticket is locked for 1 minute, providing a window to complete the payment.
• During the lock period, the ticket is unavailable for purchase by others. If the payment is not completed within 1 minute, the ticket is released.
• Ticket prices can be modified as long as the ticket is not locked.

Services

The data mangement between each microservices is done using NATS Streaming Server.
