# Portfolio Improvements Summary
|
|
|
|
**Date**: January 8, 2026
|
|
**Status**: ✅ All Issues Resolved
|
|
|
|
---
|
|
|
|
## 🎉 Issues Fixed
|
|
|
|
### 1. Safari `originalFactory.call` Error ✅
|
|
|
|
**Problem**: Runtime TypeError in Safari when visiting the site during development.
|
|
|
|
**Error Message**:
|
|
```
|
|
Runtime TypeError
|
|
undefined is not an object (evaluating 'originalFactory.call')
|
|
```
|
|
|
|
**Root Cause**:
|
|
- React 19 + Next.js 15.5.9 + Webpack's module concatenation causing factory initialization issues
|
|
- Safari's stricter module handling exposed the problem
|
|
- Mixed CommonJS/ES6 module exports in `next.config.ts`
|
|
|
|
**Solution**:
|
|
1. Fixed `next.config.ts` to use proper ES6 module syntax (`export default` instead of `module.exports`)
|
|
2. Disabled webpack's `concatenateModules` in development mode for Safari compatibility
|
|
3. Added proper webpack optimization settings
|
|
4. Cleared `.next` build cache
|
|
5. Updated Jest configuration for Next.js 15 compatibility
|
|
|
|
**Files Modified**:
|
|
- ✅ `next.config.ts` - Fixed module exports and webpack config
|
|
- ✅ `jest.setup.ts` - Updated for Next.js 15 + React 19
|
|
- ✅ `jest.config.ts` - Modernized configuration
|
|
|

|
|
|
|
### 2. n8n Webhook Integration ✅
|
|
|
|
**Problem**: n8n status endpoint returning HTML error page instead of JSON.
|
|
|
|
**Error Message**:
|
|
```
|
|
Error fetching n8n status: SyntaxError: Unexpected token '<', "<!DOCTYPE "... is not valid JSON
|
|
```
|
|
|
|
**Root Cause**: Missing `/webhook/` prefix in the API URL path.
|
|
|
|
**Solution**:
|
|
Updated all n8n API routes to include the correct `/webhook/` prefix:
|
|
|
|
```diff
|
|
- ${process.env.N8N_WEBHOOK_URL}/denshooter-71242/status
|
|
+ ${process.env.N8N_WEBHOOK_URL}/webhook/denshooter-71242/status
|
|
```
|
|
|
|
**Files Modified**:
|
|
- ✅ `app/api/n8n/status/route.ts` - Fixed webhook URL
|
|
- ✅ `app/api/n8n/generate-image/route.ts` - Fixed webhook URL
|
|
- ✅ `app/api/n8n/chat/route.ts` - Already correct
|
|
- ✅ `env.example` - Added n8n configuration
|
|
|
|
**Test Results**:
|
|
```json
|
|
{
|
|
"status": {"text": "idle", "color": "yellow"},
|
|
"music": null,
|
|
"gaming": null,
|
|
"coding": null,
|
|
"timestamp": "2026-01-08T00:57:20.932Z"
|
|
}
|
|
```

## ⚡ Performance Optimizations
|
|
|
|
### 5. API Request Optimization ✅
|
|
|
|
**Changes**:
|

|
|
- Reduces unnecessary requests by 66%
|
|
- No user-visible impact (data updates at same rate)
|
|
|
|
2. **Smarter Caching**:
|
|
- Changed from `cache: "no-store"` to `cache: "default"`
|
|
- Respects server-side cache headers
|
|
- Reduces server load
|
|
|
|
3. **Request Analysis**:
|
|
- n8n Status: 30s intervals ✅ (optimized)
|
|
- Projects API: Once on load ✅ (already optimal)
|
|
- Chat API: User-triggered only ✅ (already optimal)
|
|
|
|
**Before**: ~360 requests/hour per user
