I need a complete, browser-accessible ticket booking system that lets customers choose an event, select seats or ticket quantities, pay online, and instantly receive a digital ticket/confirmation email. The core build should sit entirely on the web—no native mobile work is required—so clean, responsive front-end code and a secure, well-documented back-end are essential. Implement a Node.js server that provides a RESTful API for an event ticket booking system with the following core functionalities: 1. Initialize an event with a set number of available tickets. 2. Allow users to book tickets concurrently. 3. Implement a waiting list for when tickets are sold out. 4. Provide endpoints to view available tickets and the waiting list. 5. Handle ticket cancellations and automatic assignment to waiting list users. 6. Save the order details to a RDBMs. Detailed Requirements 1. Server Setup • Use [login to view URL] to create the server. • Implement proper middleware for parsing JSON requests. • Use a RDBMs to store the order details. 2. Data Management • Use RDBMS or in-memory storage. Use migrations to manage the database schema. • Design efficient data structures for storing event information, bookings, and waiting lists. 3. API Endpoints Implement the following RESTful endpoints: a. POST /initialize • Initialize a new event with a given number of tickets. b. POST /book • Book a ticket for a user. • If sold out, add the user to the waiting list. c. POST /cancel • Cancel a booking for a user. • If there’s a waiting list, automatically assign the ticket to the next user in line. d. GET /status/:eventId • Retrieve the current status of an event (available tickets, waiting list count). 4. Concurrency Handling • Ensure thread-safety for all operations. • Properly handle race conditions, especially for booking and cancellation operations. 5. Error Handling • Implement comprehensive error handling for all possible scenarios. • Provide meaningful error messages in the API responses. 6. Test-Driven Development (TDD) • Write unit tests for all core functionalities before implementing them. • Achieve at least 80% test coverage. • Include integration tests for API endpoints. 7. Code Quality • Follow Node.js and JavaScript best practices. • Use ES6+ features appropriately. • Implement modular and maintainable code structure. Implementation Steps 1. Set up the project structure and install necessary dependencies. 2. Write failing tests for each core functionality (TDD approach). 3. Implement the data structures for in-memory storage. 4. Create the [login to view URL] server and set up basic routing. 5. Implement each API endpoint, making the tests pass as you go. 6. Add concurrency handling and ensure thread-safety. 7. Implement comprehensive error handling. 8. Refactor and optimize your code. 9. Write integration tests for the API endpoints. 10. Document your code and API. Evaluation Criteria 1. Correctness of implementation 2. Proper handling of concurrent requests 3. Effective use of Node.js asynchronous features 4. Comprehensive error handling and edge case management 5. Code organization, modularity, and readability 6. Test coverage and quality of tests 7. RESTful API design principles 8. Performance and scalability considerations Submission Guidelines 1. Provide a GitHub repository with your complete code. 2. Include a [login to view URL] with: • Setup and running instructions • Brief explanation of your design choices • API documentation 3. Ensure all tests are passing and include instructions for running them. Bonus Points • Implement rate limiting for the API endpoints. • Add basic authentication for sensitive operations. • Implement a simple logging system for tracking operations

The biggest challenge here is ensuring a robust, thread-safe ticket booking system that handles concurrent requests flawlessly while maintaining accurate seat/ticket availability and automatically managing waiting lists. Many booking systems fail under simultaneous bookings, leading to overselling or lost data. I specialize in building Node.js/Express.js backends with RESTful APIs for high-concurrency scenarios, implementing in-memory or RDBMS-backed storage, comprehensive error handling, and test-driven development to guarantee reliability, maintainability, and predictable performance. I’ll develop your ticketing system using ES6+ Node.js best practices, modular architecture, and TDD, covering initialization, booking, cancellation, status retrieval, and waiting-list management. Concurrency safeguards will prevent race conditions, while integration tests and 80%+ unit test coverage ensure correctness. I’ll also provide clear documentation, a GitHub repo with setup instructions, and guidance for deployment, with optional rate-limiting, authentication, and logging as needed.

Hello Emmanuel, I’m confident I can build your web-based ticketing platform. I have 6+ years as a full-stack developer specializing in Node.js, Express, RESTful APIs, and RDBMS (PostgreSQL/MySQL), and I’ve implemented concurrent booking and queueing logic before. You need a browser-accessible system that initializes events, handles concurrent bookings, maintains a waiting list when sold out, supports cancellations with automatic reassignment, exposes status endpoints, and persists orders with migrations, all covered by tests and clear docs. I’ll follow a TDD approach (Jest, Supertest), build the API with Express, use migrations (Knex/Sequelize) and PostgreSQL for transactional safety, and handle concurrency via DB transactions/advisory locks and careful error handling. I’ll provide integration tests, API docs, and CI. I can deliver an MVP in 7 days and full delivery with tests and docs in 14 days. Please feel free to contact me so we can discuss more details. I am looking forward to the chance of working together. Best regards, Billy Bryan.

Building a web-based ticketing platform that handles real-time bookings, waiting lists, and concurrency isn’t just complex—it’s risky if the system misses a race condition or lets errors slip through. Without robust concurrency handling and meaningful error messages, ticket sales can be lost or customer trust eroded fast. You’ll get a ready-to-deploy browser-accessible platform with clean, responsive code, a secure and well-documented Node.js API, and test coverage above 80 percent to ensure reliability under real-world load. We’ll start by structuring the database and core API in Express, then implement comprehensive unit and integration tests before building out the endpoints and concurrency logic. After that, I’ll document everything clearly and optimize error handling across the board. What’s the top priority for you: speed to launch, reliability under heavy traffic, or seamless integration with your payment provider?
