The Folder Structure No One Teaches You (But Every Developer Needs)
Every developer has opened a messy project and immediately wanted to cry. Maybe the routes folder had configs, the utils folder had business logic, and the components folder was full of files named test-final-new.js. But here’s the secret: folder structure isn’t magic it’s just a series of small decisions that nobody teaches, yet every project depends on. In this post, you’ll learn how to design…
Developers often face the daunting challenge of disorganized project folders. The source material outlines a simple solution to this issue: a clean folder structure that evolves with the project. Key points include:
A clean folder structure enhances productivity by preventing code decay, accelerating onboarding, speeding up debugging, and facilitating safe refactoring. It doesn’t require perfection, just consistency.
The source recommends a three-layer mental model to structure projects:
- /core: Contains core business logic.
- /features: Houses product modules.
- /shared: Provides reusable utilities.
This structure accommodates various types of projects, including frontend, backend, and microservices.
The source provides practical examples. For a React project, a well-organized folder structure includes:
- /src
- /components: Reusable UI components.
- /hooks: Custom React hooks.
- /pages: Route-level pages.
- /contexts: Global state management (auth, theme, user).
- /lib: API clients, configuration, external services.
- /assets: Images, icons, fonts.
For a small Express API backend, a minimalist folder structure includes:
- /src
- /routes: Route definitions.
- /controllers: Request handling logic.
- /services: Business logic.
- /models: Database schemas.
- /utils: Shared helpers (validators, formatters).
The takeaway: Start with simple, consistent folder structures aligned with your project’s core questions. Refactor only when necessary, as this will benefit both your current and future self, as well as your team.
