Welcome to the Module Best Practices guide! Whether you're developing software, organizing code, or designing systems, modules are essential for scalability and maintainability. Here are key principles to follow:

1. Single Responsibility Principle (SRP) 🧠

Each module should have one and only one reason to change. Focus on encapsulating a single functionality, like data handling or business logic.

Single Responsibility Principle

2. Avoid Global State ⚠️

Minimize reliance on global variables. Instead, pass dependencies explicitly to keep modules predictable and testable.

📌 For deeper insights, check our Chinese version of module design for localized examples.

3. Use Clear Naming 📝

Name modules descriptively (e.g., auth_utils, data_fetcher). Avoid vague terms like helper or utils without context.

Clear Naming Convention

4. Version Control 🔄

Tag modules with semantic versioning (e.g., v1.2.3). This ensures compatibility and simplifies updates.

  • Major version: Breaking changes
  • Minor version: New features
  • Patch version: Bug fixes

5. Optimize Performance ⚡

  • Lazy load non-critical modules
  • Minify module assets (JavaScript/CSS)
  • Use caching strategies for frequently accessed modules

6. Security First 🔒

  • Validate inputs in all modules
  • Restrict module access via authentication/authorization
  • Regularly audit dependencies for vulnerabilities
