Building the Modern Web: A Comparative Study of MERN And FERN Technology Stacks

This paper compares the MERN and FERN technology stacks, focusing on their core components, strengths, and limitations for modern full-stack development. MERN (MongoDB, Express.js, React.js, Node.js) provides flexibility and scalability for large-scale applications requiring robust backend control. FERN (Firebase, Express.js, React.js, Node.js), on the other hand, leverages Firebase’s real-time capabilities, making it ideal for applications requiring real-time functionality with minimal backend setup. Key differences between these stacks include backend complexity, real-time synchronization, scalability, and cost considerations. The comparison aims to help developers select the most appropriate stack based on project requirements
