Eternal Blue Esport using PERN stack

The growing market for eSports is fueling demand for robust, highly scalable, interactive ecosystems to support competitive gaming, community interaction, and real-time data processing. The authors will present an eSports platform named Eternal Blue, a full-stack eSports web application that was built using the PERN stack (PostgreSQL, Express.js, React, and Node.js). The system contains several modules to support organizing eSports tournaments, tracking, live scoring, user authentication, matchmaking functions, and dynamic leaderboards with real-time updates. These platform modules use advanced web technologies to provide high throughput, modular design, and scalability, supporting thousands of concurrent users the site can provide performance activity based on user load. The back-end was developed using Node.js and Express for handling RESTful API requests and secure communication while the front-end experience was designed using React, which enabled a high-quality user experience for a scalable and highly-interactive browser web application. PostgreSQL was the database also for relational data storage and complex data queries. The software also had socket-based functions for live communications with other players. This paper examines the architecture of the application, challenges in implementation, and performance assessment of the PERN stack for the development of new eSports applications.
