🎯 Key Corrections Made

Event Flow Accuracy

  • Before: Documentation showed incorrect event sequences
  • After: Event flows now match the actual implementation in E2E tests

Event Names

  • Before: Used outdated event names like DepositBusinessValidationEvent, DepositConversionDoneEvent, DepositRequestedEvent (camelCase without dots)
  • After: All event names use correct format: Deposit.Requested, Deposit.Validated, Deposit.CurrencyConverted, Payment.Initiated, etc. (with dots)

Handler Structure

  • Before: Referenced non-existent handlers or incorrect responsibilities
  • After: Accurately describes current handler implementations in pkg/handler/

File Paths

  • Before: Incorrect paths to source files (e.g., pkg/domain/account/events/)
  • After: All paths point to actual files in the current codebase (e.g., pkg/domain/events/)

API Endpoints

  • Before: Some endpoints documented incorrectly (e.g., /account/transfer, /login)
  • After: All endpoints match actual routes (e.g., /account/:id/transfer, /auth/login)

Implementation Details

  • Before: Generic or outdated code examples
  • After: Actual code patterns and structures from current implementation

🧪 Verification

All documentation updates were verified against:

  1. Current source code in pkg/domain/events/
  2. Handler implementations in pkg/handler/
  3. E2E test flows in pkg/handler/e2e_event_flow_test.go
  4. Actual project structure and file organization

7. Event Name Synchronization (Latest Sync)

  • Issue: Multiple documentation files used outdated event names without dot notation
  • Fix: Updated all event names to use correct format with dots (e.g., Deposit.Requested, Deposit.Validated, Deposit.CurrencyConverted)
  • Files Updated:
  • docs/refactoring/event-driven-lessons.md
  • docs/refactoring/event-driven-deposit-flow.md
  • docs/refactoring/event-driven-withdraw-flow.md
