Folder Structure Matters More Than You Think

You write clean code.
You use good naming conventions.
Your logic is solid.

But… your project still feels messy, unscalable, and hard to onboard others into?

👉 The culprit? Your folder structure.

Sounds boring? It’s not.

Think of it like your kitchen — you could have all the spices and tools, but if everything is dumped into one drawer, you’ll hate cooking in there.
It’s the same with your codebase.

Let’s break this down.

Why Folder Structure Is a Silent Power Move

  • Scalability: Good structure makes your project grow without becoming chaotic.
  • Onboarding: New devs can start contributing fast.
  • Maintenance: Finding bugs and files becomes painless.
  • Separation of concerns: You reduce dependency hell and cognitive overload.
  • Team collaboration: Everyone follows the same system, minimizing merge conflicts and confusion.

Imagine This Scenario 👇

You're joining a new project. You open the repo, and this greets you:

/src
  /components
  /utils
  /helpers
  /pages
  App.js
  index.js
  routes.js
  config.js
Enter fullscreen mode Exit fullscreen mode

Looks okay, right? But as the app grows, you get:

  • utils.js, utils_v2.js, utilsFinal.js
  • Components used once but living in global components/
  • Repeated logic scattered across unrelated files

You spend more time finding code than writing it.


Let’s Talk Real-World Folder Patterns (With Examples)

1. Feature-Based Structure (Recommended for Scale)

/src
  /features
    /auth
      AuthPage.jsx
      authSlice.js
      authAPI.js
    /dashboard
      Dashboard.jsx
      dashboardSlice.js
  /shared
    /components
    /hooks
    /utils
Enter fullscreen mode Exit fullscreen mode

👉 Group everything related to a feature in one place.

2. Domain-Driven Structure

Helpful for larger, backend-heavy apps.

/src
  /domains
    /user
      UserService.js
      UserController.js
      UserRoutes.js
    /product
      ProductService.js
Enter fullscreen mode Exit fullscreen mode

Pro Tips to Get It Right ✅

  • 📁 Group by feature, not type (no more components/, styles/, utils/ dumps)
  • 🧠 Think from the future — "What happens when I add 5 more modules?"
  • 🔄 Be consistent — once you pick a pattern, stick to it
  • 📦 Keep shared code in a separate /shared or /common folder
  • 🧪 Tests should live next to the file they test (Button.test.js beside Button.js)
  • 🔍 Name folders clearly (auth, dashboard, products, not misc or stuff)
  • 🛠️ Use index files for clean imports:
// Instead of:
import AuthPage from '../../features/auth/AuthPage'

// Do this:
import { AuthPage } from '../../features/auth'
Enter fullscreen mode Exit fullscreen mode

Bonus: Use a CLI Template Generator

Tools like Plop.js let you automate consistent folder and file creation.

Set it up once and avoid manual boilerplate forever:

plop.setGenerator('component', {
  description: 'Create a new component',
  prompts: [/* name, type, etc */],
  actions: [/* generate folder + files */]
})
Enter fullscreen mode Exit fullscreen mode

Super handy in teams and production setups.

Remember: Structure Is Invisible Until It Hurts

No one notices good folder structure — until it’s gone.

But when it’s bad?

  • Everything breaks.
  • Team slows down.
  • Deadlines slip.
  • New devs quit.

It's not "just folders."
It’s how you architect your brain into the app.
