+# Node.js Backend Project Guidelines
+---
+
+### Project Setup
+- Use **Node.js (v18+)** and **Express.js** for building APIs.
+- Store configuration in environment variables (`.env`), and use the config files already present, if they exist.
+- follow ES6+ JavaScript conventions.
+
+### Style & Formatting
+- Use **camelCase** for variables and function names.
+- Apply **2-space indentation**.
+- Prefer **single quotes** for strings.
+- Always use **async/await** for asynchronous operations.
+- Use **ESLint** with the **Airbnb Base** style guide (see `.eslintrc` or `package.json`).
+
+
+### Architecture & Patterns
+- Organize code into clear layers: `routes/`, `controllers/`, `services/`, `models/`.
+- Keep business logic in services; route handlers should be thin.
+
+### Error Handling & Security
+- Implement centralized error handling middleware (must include status codes and JSON error messages), or adhere to existing code that handles it
+- Always validate and sanitize inputs.
+- For cookies or sessions, ensure `httpOnly`, `secure` (in prod), and `sameSite: 'strict'`.
+
+### Testing
+- Use **Mocha** for unit tests, always look for /tests/*/*.js or /test/*.js to learn the styling and test formats
+- Maintain ≥80% test coverage.
+
+### Build & Deployment
+- Build command: `npm run build`.
+- Start server with `npm start`;
+
+### Documentation & Maintenance
+- Tag PRs with [FEATURE], [BUGFIX], or [REFACTOR].

+
+# Test File Guidelines
+- Write clear, descriptive test names.
+- Use `describe` and `it` blocks from Jest.
+- Clean up any test data or mocks after each test.
