React Best Practices Every Developer Has to Follow (Lessons From My Journey)
When I wrote my first React component, I treated it like “just another front-end library.” Years later, after building production apps in React, Vue, Angular, Laravel, Flutter, and more, I’ve come to see React as an ecosystem where discipline matters more than syntax.
In this article, I’ll walk through the React best practices every developer has to follow, not as theory, but as patterns I’ve learned (sometimes the hard way) while shipping real products: from e‑commerce and admin panels to mobile apps and notification libraries.
- Start With a Scalable Project & Folder Structure
One of the biggest early mistakes I made with React was letting the project structure “grow organically.” It always started fine and always ended as a mess.
Now, I start every React project with a scalable, predictable structure that supports growth from day one.
A pattern that has served me well is component‑centric structure:
- Group each component with everything it needs:
- JSX/TSX file
- styles
- tests
- API helpers (if they’re tightly coupled)
For example:
- components/Login/Login.jsx
- components/Login/Login.scss
- components/Login/Login.test.js
- components/Login/LoginAPI.js
On some projects, especially larger ones, I invert the structure and group by type instead of feature:
components/– all UI components (Login, Profile, User)- apis/ – all API wrappers (LoginAPI, ProfileAPI, UserAPI)
Both approaches can work. The key is: pick one, document it, and stick to it. When teams don’t agree on structure, React projects decay quickly.
- Write Reusable Components and Respect DRY
