Global Best Practices

Priority: P0 (FOUNDATIONAL)

🏗 Core Principles

  • SOLID: Follow SRP (One reason to change), OCP (Open to extension), LSP, ISP, DIP.
  • KISS/DRY/YAGNI: Favor readability. Abstract repeated logic. No "just in case" code.
  • Naming: Intention-revealing (isUserAuthenticated > checkUser). Follow language casing.

🧹 Code Hygiene

  • Size Limits: Functions < 30 lines. Services < 600 lines. Utils < 400 lines.
  • Early Returns: Use guard clauses to prevent deep nesting.
  • Comments: Explain why, not what. Refactor instead of commenting bad code.
  • Sanitization: Validate all external inputs.

Anti-Patterns

  • No hardcoded constants: Use named config/env vars.
  • No deep nesting: Guard clauses eliminate the Pyramid of Doom.
  • No global state: Prefer dependency injection.
  • No empty catches: Always handle, log, or rethrow.
