Coding Guidelines

• Follow the Airbnb JavaScript Style Guide
• Suggest splitting files into smaller, focused units when appropriate
  • Keep code files under 250 lines, if the file is over 250 lines, split it into multiple files based on the functionality.
• Add comments for non-obvious logic. Keep all text in English
• All new features should have corresponding unit tests

Dependencies and Testing

• Inject dependencies through a deps object parameter for testability
• Example:

  export const functionName = async (
    param1: Type1,
    param2: Type2,
    deps = {
      defaultFunction1,
      defaultFunction2,
    }
  ) => {
    // Use deps.defaultFunction1() instead of direct call
  };

• Mock dependencies by passing test doubles through deps object
• Use vi.mock() only when dependency injection is not feasible
