This article, published on GeeksforGeeks, provides a comprehensive guide to monitoring and logging in MERN stack applications (MongoDB, Express.js, React.js, Node.js). It emphasizes the critical role of monitoring and logging in maintaining the health, performance, and security of web applications.The article covers key reasons why monitoring and logging are essential, including real-time error tracking, performance optimization, security monitoring, user behaviour insights, and compliance with industry standards. It demonstrates practical approaches for implementing these practices using widely-used tools and libraries:<ul><li>Morgan: Middleware for logging HTTP requests in Express.js applications, enabling detailed request tracking and easier debugging.</li><li>Winston: A flexible logging library for Node.js that supports multiple transports, custom log levels, and comprehensive logging across the application.</li><li>PM2: A Node.js process manager that ensures applications run smoothly, offering features like automatic restarts, load balancing, and detailed monitoring of system resources.</li></ul>By following these techniques, developers can proactively identify issues, optimize performance, and maintain application stability. The article also showcases my ability to explain complex technical concepts clearly while demonstrating hands-on expertise with the MERN stack and real-world application maintenance practices.This work highlights my full-stack development skills, practical knowledge of Node.js, Express, React.js, and MongoDB, and competence in building maintainable, high-performance applications. It is an example of my capability to combine development skills with technical documentation for a professional audience.
