When should you choose MERN instead of MEVN or PERN?

Explains differences among MERN, MEVN, and PERN stacks, and when utilizing MERN makes strategic sense.

• MERN (MongoDB, Express, React, Node.js) is preferred when you need React’s rich component ecosystem, state management flexibility, and React Native compatibility. • MEVN uses Vue instead—more lightweight and easier for rapid prototyping. • PERN utilizes PostgreSQL for structured relational data needs. Choose MERN when building scalable SPAs with rich UI and unified JavaScript workflows across frontend and backend. Tags: mern-stack, mevn-stack, pern-stack, javascript, full-stack, react, vue
