Online Event Ticket Booking System

A full-stack event ticketing platform (MERN) supporting three roles — attendees who buy tickets, organizers who create and manage events, and admins who oversee the platform — with real payment processing and QR-coded digital tickets.

Stack

Backend: Node.js, Express 5, MongoDB + Mongoose, JWT auth, bcryptjs, Nodemailer

Frontend: React 19 + Vite, React Router 7, Axios, Tailwind CSS 4, Recharts, react-qr-code, react-toastify

Features

• Multi-tier ticketing — organizers define ticket types per event (e.g. General, VIP, Early Bird) with independent pricing and inventory; attendees can buy multiple types in a single order
• Payment processing — integrated with PayHere (Sri Lanka), including MD5 hash-signed transactions so payment callbacks can be verified server-side rather than trusted blindly
• QR-coded tickets — each completed purchase generates a unique QR payload embedding event/ticket data, emailed to the buyer for entry scanning
• Role-based access control — attendee / organizer / admin middleware on top of JWT auth; the token is re-checked against the live user record on every request, so a deleted or deactivated account is denied even with a still-valid token
• Organizer dashboard — event management and sales analytics (Recharts)
• Email notifications — booking confirmations and account flows via Nodemailer

Architecture

Routes → Service layer → Mongoose models, kept deliberately separate so request handling, business logic, and data access don't blur together (e.g. TicketService owns purchase/payment logic and QR generation; routes stay thin).
