Usage

1. Development Mode

Run the app with Nodemon for auto-reloading:

npm run dev

Access the application at: http://localhost:8000

2. Build for Production

Compile the TypeScript files to JavaScript:

npm run build

Run the compiled app:

npm start

---

Scripts

• npm run dev: Start the app in development mode with Nodemon.
• npm run build: Compile TypeScript to JavaScript.
• npm start: Run the compiled app in production mode.
• npm run lint: Check for linting issues.
• npm run lint:fix: Fix linting issues automatically.

---

Best Practices

• Type Annotations: Use TypeScript’s powerful type system to avoid runtime errors.
• Folder Organization: Keep your business logic separate from your route definitions.
• Environment Variables: Use .env files for managing secrets (e.g., database URLs).
• Error Handling: Implement consistent error responses using middleware.
• Testing: Add unit and integration tests using a framework like Jest.
