Service Locator App Using MERN Stack: A Comprehensive Solution for Connecting Service Providers and Households

In the evolving landscape of web application development, service management patterns play a crucial role in building scalable, maintainable, and efficient systems. This research focuses on implementing the Service Locator design pattern within the MERN (MongoDB, Express.js, React, Node.js) stack, but introduces a significant modification: replacing MongoDB with Hygraph, a headless CMS powered by GraphQL. The goal is to study how centralizing the access and management of services impacts the system’s modularity, scalability, and performance. By leveraging Hygraph’s flexible and dynamic schema capabilities, the architecture allows applications to adapt quickly to content changes without heavy backend modifications. This research shows that combining a Service Locator with a modern CMS like Hygraph creates a decoupled, efficient architecture suitable for content-heavy, dynamic applications
