04 - Code Structure and Organization

Organize code for maintainability: folder structure, naming conventions, separation of concerns and configuration management with Copilot.

What you'll learn

• Feature-Based Structure: Organize by feature, not by file type
• Naming Conventions: kebab-case for files, PascalCase for classes
• Separation of Concerns: Controller -> Service -> Repository
• Config Management: Centralize with schema validation (Zod)
• Barrel Exports: Index.ts for clean imports
