From fd14b43ee72066652c7ba14e310431ea5311a127 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 5 Nov 2025 15:31:02 +0000 Subject: [PATCH 1/5] Add initial Ollama/LLM integration Implement core LLM functionality with Ollama integration to enable AI-powered features in the browser. This establishes the foundation for local model inference, chat capabilities, and vision-based page analysis. Changes: - Create OllamaService for managing Ollama server lifecycle and API communication with support for streaming responses - Add IPC handlers for model management (list, pull, delete) and inference operations (generate, chat) - Update preload script with whitelisted Ollama IPC channels for secure renderer-main communication - Enhance ChatStore with streaming support and message management - Create ModelStore for tracking installed models and Ollama status - Update ChatSidebar with real Ollama integration, model selection, and streaming message display - Add shared TypeScript types for LLM operations (OllamaModel, ChatMessage, PullProgress, etc.) - Add axios dependency for HTTP communication with Ollama API Technical details: - Ollama service auto-starts if not running - Streaming inference via async generators - Proper error handling and validation - Secure IPC with channel whitelisting - Real-time model status checking Related to: TECH_BRIEFING.md sections on LLM Integration and Architecture Philosophy --- package.json | 1 + src/main/ipc/handlers.ts | 134 ++++++++ src/main/preload.ts | 14 +- src/main/services/ollama.ts | 310 +++++++++++++++++++ src/renderer/components/Chat/ChatSidebar.tsx | 138 +++++++-- src/renderer/store/chat.ts | 55 +++- src/renderer/store/models.ts | 51 +++ src/renderer/styles/globals.css | 10 +- src/shared/types.ts | 42 +++ 9 files changed, 717 insertions(+), 38 deletions(-) create mode 100644 src/main/services/ollama.ts create mode 100644 src/renderer/store/models.ts diff --git a/package.json b/package.json index 9b8656a..97e73b7 100644 --- a/package.json +++ b/package.json @@ -65,6 +65,7 @@ "wait-on": "^9.0.1" }, "dependencies": { + "axios": "^1.7.0", "better-sqlite3": "^12.4.1", "react": "^19.2.0", "react-dom": "^19.2.0", diff --git a/src/main/ipc/handlers.ts b/src/main/ipc/handlers.ts index 055cb60..bbf78f7 100644 --- a/src/main/ipc/handlers.ts +++ b/src/main/ipc/handlers.ts @@ -6,6 +6,8 @@ import { validateString, validateBoolean, } from '../utils/validation';

Critical Fixes: 1. Fixed premature listener cleanup in AvailableModels (CRITICAL) - Previously: unsubscribe() called immediately after invoke() - Problem: Progress events were not received during download - Fix: Delayed cleanup with timeout after streaming completes - Impact: Downloads now properly show progress updates 2. Fixed missing Tailwind CSS classes in InstalledModels - Replaced: bg-destructive/10 text-destructive (undefined) - With: bg-red-500/10 text-red-600 dark:text-red-400 - Impact: Delete button now renders correctly 3. Fixed useEffect dependencies in ChatSidebar - Added exhaustive-deps eslint-disable with explanation - Reason: Including all deps would cause infinite re-fetch loop - Impact: Eliminates React warnings, prevents bugs 4. Improved type safety - Replaced: progress: any - With: progress: PullProgress - Impact: Better TypeScript checking, fewer runtime errors 5. Enhanced error handling - Replaced alert() with proper error state management - Added console.error for debugging - Added TODO comments for future toast notifications - Impact: Better user experience and debugging 6. Improved user confirmations - Enhanced confirm() dialog messages - Added window.confirm explicit calls - Added TODO for future modal component - Impact: Clearer user intent confirmation Documentation: - Created IMPLEMENTATION_ISSUES.md documenting all findings - Includes severity ratings and recommended fixes - Serves as technical debt tracker Files Modified: - src/renderer/components/Models/AvailableModels.tsx - src/renderer/components/Models/InstalledModels.tsx - src/renderer/components/Chat/ChatSidebar.tsx - IMPLEMENTATION_ISSUES.md (new) All critical bugs are now fixed.
