When should a developer choose MERN over MEVN or PERN?

This compares MERN (MongoDB, Express, React, Node) versus other JavaScript stacks like MEVN (Vue) and PERN (PostgreSQL), and asks when MERN is the most suitable choice.

• MERN uses MongoDB (NoSQL) and React (UI library). It excels in JSON-driven, document-based apps. • MEVN uses Vue.js instead of React—simpler syntax, ideal for gradual adoption or smaller teams. • PERN replaces MongoDB with PostgreSQL for relational data and strict schemas. Choose MERN when: • You need schema flexibility and dynamic data. • You want full JavaScript flow across client-server-database. • You prefer React’s ecosystem and component-based architecture for rich frontend apps.
