# Session: API Refactor - Error Handling
**Date:** 2026-01-19
**Started:** 10:00
**Last Updated:** 13:30
---
## Current State
Standardizing error handling across all API endpoints. Moving from ad-hoc try/catch to centralized error middleware.
### Completed
- [x] Created AppError class with status codes
- [x] Built global error handler middleware
- [x] Migrated `/users` routes to new pattern
- [x] Migrated `/products` routes
### Key Findings
- 47 endpoints with inconsistent error responses
- Some returning `{ error: message }`, others `{ message: message }`
- No consistent HTTP status codes
### Error Response Standard
```javascript
{
success: false,
error: {
code: 'VALIDATION_ERROR',
message: 'Email is required',
field: 'email' // optional, for validation errors
}
}
```
### Notes for Next Session
- Migrate remaining routes: `/orders`, `/payments`, `/admin`
- Add error logging to monitoring service
### Context to Load
```
src/middleware/errorHandler.js
src/utils/AppError.js
```
