How I Structure My Fullstack Projects in 2025

🧠 Why Project Structure Matters in 2025

As projects scale, a messy folder structure becomes a major roadblock debugging gets tougher, onboarding becomes a nightmare, and features take longer to ship. In 2025, I follow a modular, layered approach across both frontend and backend to maintain clarity and speed.

✨ Key Principles I Follow

1. Frontend follows “feature-first” design

Rather than stuffing everything under /components, I use /features to group logic by domain. Each feature contains its own:

• Local state

• API interactions

• Reusable components

✅ Example:
/features/auth/ may have Login.tsx, useLogin.ts, and authAPI.ts.

2. Backend is layered: Routes → Controller → Service → Model

This separation allows easy testing and prevents bloated route files.

✅ Example Flow:
POST /api/users/register → userRoutes.js → userController.registerUser() → userService.createUser() → UserModel.save()

3. Shared types via TS config aliases

By defining @types and @constants in the shared/ folder, I eliminate duplication across frontend and backend.

4. .env and config separation

All sensitive keys are managed via .env, and structured inside server/config or client/src/config.
