A Study on MERN Stack and Role in Web Application Development

Abstract: This research paper shows how to create a complete web application using the MERN stack which includes MongoDB and Express.js and React and Node.js. The research study aims to evaluate how effective and scalable and efficient MERN applications function in contemporary web development. Previous studies have shown that using a single JavaScript environment benefits developers by making their work easier and their code more understandable. The paper introduces a task management system that provides user authentication and role-based access control and real-time task tracking and file management. The system aims to address limitations identified in earlier works, including lack of real- time synchronization and limited user interaction capabilities. The results show that MERN stack applications create web applications which perform well and adapt to different requirements and handle increased user traffic. The research study shows that the MERN stack serves as an effective and practical solution to develop contemporary web applications which scale effectively for task management and group work.
