From Monoliths to Modules: The React Revolution Your Codebase Desperately Needs

Why Codebases Don’t Age Gracefully

Every React project starts the same way: small, focused, and nimble. You spin up a new component, maybe a HomePage.jsx, add a few hooks, mix in some CSS, and you’re off to the races.

This is the monolithic component problem: where a single file tries to do too much. It works for MVPs and hackathons but becomes a nightmare as the application grows. Modular components, on the other hand, promote clean architecture, scalability, and developer sanity.

Here are some of the most common issues developers face with monolithic components:
