Critical fix for Docker deployment where AI features were trying to connect
to localhost:11434 instead of using configured provider (Ollama Docker service
or OpenAI).
Problems fixed:
1. Reformulation (clarify/shorten/improve) failing with ECONNREFUSED 127.0.0.1:11434
2. Auto-labels failing with same error
3. Notebook summaries failing
4. Could not switch from Ollama to OpenAI in admin
Root cause:
- Code had hardcoded fallback to 'http://localhost:11434' in multiple places
- .env.docker file not created on server (gitignore'd)
- No validation that required environment variables were set
Changes:
1. lib/ai/factory.ts:
- Remove hardcoded 'http://localhost:11434' fallback
- Only use localhost for local development (NODE_ENV !== 'production')
- Throw error if OLLAMA_BASE_URL not set in production
2. lib/ai/providers/ollama.ts:
- Remove default parameter 'http://localhost:11434' from constructor
- Require baseUrl to be explicitly passed
- Throw error if baseUrl is missing
3. lib/ai/services/paragraph-refactor.service.ts:
- Remove 'http://localhost:11434' fallback (2 locations)
- Require OLLAMA_BASE_URL to be set
- Throw clear error if not configured
4. app/(main)/admin/settings/admin-settings-form.tsx:
- Add debug info showing current provider state
- Display database config value for transparency
- Help troubleshoot provider selection issues
5. DOCKER-SETUP.md:
- Complete guide for Docker configuration
- Instructions for .env.docker setup
- Examples for Ollama Docker, OpenAI, and external Ollama
- Troubleshooting common issues
Usage:
On server, create .env.docker with proper provider configuration:
- Ollama in Docker: OLLAMA_BASE_URL="http://ollama:11434"
- OpenAI: OPENAI_API_KEY="sk-..."
- External Ollama: OLLAMA_BASE_URL="http://SERVER_IP:11434"
Then in admin interface, users can independently configure:
- Tags Provider (for auto-labels, AI features)
- Embeddings Provider (for semantic search)
Result:
✓ Clear errors if Ollama not configured
✓ Can switch to OpenAI freely in admin
✓ No more hardcoded localhost in production
✓ Proper separation between local dev and Docker production

## Bug Fixes
### Note Card Actions
- Fix broken size change functionality (missing state declaration)
- Implement React 19 useOptimistic for instant UI feedback
- Add startTransition for non-blocking updates
- Ensure smooth animations without page refresh
- All note actions now work: pin, archive, color, size, checklist
### Markdown LaTeX Rendering
- Add remark-math and rehype-katex plugins
- Support inline equations with dollar sign syntax
- Support block equations with double dollar sign syntax
- Import KaTeX CSS for proper styling
- Equations now render correctly instead of showing raw LaTeX
## Technical Details
- Replace undefined currentNote references with optimistic state
- Add optimistic updates before server actions for instant feedback
- Use router.refresh() in transitions for smart cache invalidation
- Install remark-math, rehype-katex, and katex packages
## Testing
- Build passes successfully with no TypeScript errors
- Dev server hot-reloads changes correctly
- Added multi-provider AI infrastructure (OpenAI/Ollama)
- Implemented real-time tag suggestions with debounced analysis
- Created AI diagnostics and database maintenance tools in Settings
- Added automated garbage collection for orphan labels
- Refined UX with deterministic color hashing and interactive ghost tags
