Thanks for your effort. I will try it on my computer later.

@KariHall619 KariHall619 force-pushed the feature/ai-plugin-complete branch from 323d02b to b5c7b38 Compare September 29, 2025 12:32
Adds support for multiple AI providers including DeepSeek, Moonshot, Zhipu, and Baichuan, using an OpenAI-compatible interface.

This change enables users to configure and utilize different AI services for SQL generation, improving flexibility and allowing access to a wider range of models. Includes runtime client creation with API key support.

Addresses potential issues with unsupported providers by providing clearer error messages and fallback mechanisms. The UI is updated to reflect the new providers.
Changes the AI response format from JSON to a simpler "sql:\nexplanation:" format.

This simplifies parsing and reduces complexity, while still providing the necessary SQL query and explanation.

Updates the plugin service to return the new format and relevant metadata.
Includes debug logging to assist with troubleshooting.

有点奇怪,为什么考虑直接调用 HTTP 接口,而不是封装好的代码,比如:github.com/tmc/langchaingo

Set up Vue 3 + TypeScript project for AI plugin using deep integration approach.
This configuration enables the plugin to receive and use main app's context.

- package.json: Vue 3.3.4, Element Plus 2.10.4, no vue-i18n (uses main app's)
- vite.config.ts: IIFE build format, outputs to ../dist
- tsconfig.json: TypeScript strict mode with path aliases
- tsconfig.node.json: Node-specific TypeScript config
Define core types for plugin with deep integration approach.
AppContext interface enables plugin to receive and use main app's resources.

- AppContext: Interface for context passed from main app
- AIConfig: AI provider configuration
- Model: AI model metadata
- Message: Chat message structure
- QueryRequest/Response: API request/response types
Core business logic composable that uses main app's context for all operations.
Uses main app's API.DataQuery directly instead of creating separate API layer.

Key features:
- Receives AppContext from main app
- Uses context.API.DataQuery for all backend calls
- Configuration management with localStorage
- Message management for chat interface
- Model discovery and selection
- Connection testing

Deep integration benefits:
- No duplicate API wrapper code
- Direct access to main app's API methods
- Seamless integration with main app's infrastructure
Created all UI components that use injected AppContext for i18n and functionality.
All components inject context and use main app's t() function for translations.

Components:
- App.vue: Main container, receives context from main.ts and provides to children
- AIChatHeader.vue: Header with title, status, and settings button
- AIChatMessages.vue: Message display with SQL syntax highlighting and copy
- AIChatInput.vue: Input area with options and submit
- AIWelcomePanel.vue: Welcome screen for unconfigured state
- AISettingsPanel.vue: Configuration drawer with language sync

Key features:
- All components use inject('appContext') to access i18n
- Language switching in settings updates main app locale
- No duplicate i18n setup - uses main app's translations
- Seamless integration with main app's UI patterns
Created main.ts as plugin entry point that receives context from main app.
Exposes ATestPlugin interface on window with mount(container, context) signature.

Key features:
- Receives AppContext from main app via mount() parameter
- Creates Vue app and passes context as props to App.vue
- Uses Element Plus for UI components
- Provides unmount() for cleanup
- Exposes to window.ATestPlugin for main app access

This completes the deep integration architecture where plugin receives
and uses all resources from main app through the context parameter.
Fixed three TypeScript errors to enable successful build:
1. Removed unused Cache variable from useAIChat
2. Added type assertions to loadConfig return statements
3. Changed App import to type-only import in main.ts

Build output:
- main.js: 1.0MB (327KB gzipped) - Complete Vue app with Element Plus
- style.css: 342KB (47KB gzipped) - All styles bundled

Build successfully generates IIFE format plugin ready for deployment.
CRITICAL FIX: Language should be managed by main app only, not plugin.

Changes:
- Remove 'language' field from AIConfig interface
- Remove language selection UI from AISettingsPanel
- Remove language from localStorage save/load operations
- Remove updateLanguage() function

Correct behavior:
✅ Main app language setting automatically syncs to plugin
✅ Plugin uses context.i18n.locale reactively from main app
✅ Plugin settings focused only on AI-related configuration
❌ No language option in plugin settings (as intended)
CRITICAL BUG FIX:
- Replace DataQuery with direct fetch API calls
- DataQuery is for database queries and transforms request format
- AI plugin expects: {type: 'ai', key: 'operation', sql: 'params_json'}
- Using DataQuery caused incorrect request format to backend

IMPROVEMENTS:
- Add copiedSuccess translation key for better UX
- Fix copy success message to use proper translation
- Add detailed comments explaining API call mechanism
- Keep context parameter for future use (authentication, etc.)

This fixes the API communication between frontend and backend.
CRITICAL IMPROVEMENTS:
1. Eliminate code redundancy by extracting utilities
2. Add complete test coverage with Vitest

Code Refactoring:
- Extract config management functions to utils/config.ts
- Separate concerns: loadConfig, saveConfig, getDefaultConfig, getMockModels, generateId
- Remove 90+ lines of duplicated code from useAIChat.ts
- Better testability and maintainability

Test Infrastructure:
- Add vitest.config.ts with jsdom environment
- Add test setup with localStorage and fetch mocks
- Add test scripts: test, test:ui, test:coverage
- Add testing dependencies: @vue/test-utils, jsdom, @vitest/ui, @vitest/coverage-v8

Test Coverage:
1. utils/config.test.ts - 6 test suites covering:
   - loadConfig with various scenarios
   - saveConfig localStorage persistence
   - getDefaultConfig for all providers
   - getMockModels fallback data
   - generateId uniqueness

2. composables/useAIChat.test.ts - 6 test suites covering:
   - Initialization and configuration
   - handleQuery with success/error cases
   - handleTestConnection status management
   - refreshModels API and fallback
   - Config persistence with localStorage
   - Loading states

3. components/AIChatHeader.test.ts - Component tests:
   - Rendering with i18n context
   - Status display variations
   - Event emission
   - Integration with provide/inject

Benefits:
✅ 100% test coverage for utility functions
✅ Comprehensive composable testing
✅ Component integration tests
✅ Mock localStorage and fetch for isolation
✅ CI-ready test infrastructure
✅ Better code organization and reusability
- Create aiService to centralize all API calls
- Refactor useAIChat to use aiService instead of direct fetch
- Update tests to mock aiService for better testability
- Fix component test stubs for proper event handling
- All 27 tests passing
- Copy latest built files from dist/ to pkg/plugin/assets/
- Frontend now uses aiService for all API calls
- All 27 tests passing
- Ready for backend recompilation
- Change output directory from dist/ to pkg/plugin/assets/
- Update filenames to match Go embed expectations (ai-chat.js/css)
- Remove need for manual file copying after build
- Add clear comments explaining the configuration

Benefits:
- One-step build process: npm run build is all you need
- Eliminates manual copy step and potential errors
- Frontend changes immediately ready for backend rebuild
Changed plugin socket path from /tmp/atest-ext-ai.sock to
~/.config/atest/atest-ext-ai.sock to align with main server's
GetExtensionSocketPath() function. This resolves the "not Ready"
status issue in Store Manager.
This critical fix addresses an architectural flaw where the plugin's
Ready status depended on AI service availability, preventing cloud-only
users (who don't run local Ollama) from using the plugin.

Backend changes:
- Refactored Verify() method to only check core component initialization
  (aiEngine, config, providerManager) instead of AI service health
- Added health_check endpoint for separate AI service health checking
- Implemented handleHealthCheck() method with configurable timeout

Frontend changes:
- Added checkHealth() method in aiService to call health_check endpoint
- Fixed generateSQL() to correctly parse "sql:xxx\nexplanation:xxx" format
- Added explanation field to query response

Build improvements:
- Added build-frontend target to Makefile
- Made install-local depend on build-frontend for automated builds
- Updated help documentation

Infrastructure:
- Changed default socket path to /tmp to match stores.yaml configuration

This allows the plugin to be "Ready" even without active AI services,
enabling users to configure cloud providers (OpenAI, DeepSeek) without
requiring local Ollama installation.
Root cause: IIFE format generated `this.ATestPlugin` which failed to
properly expose the plugin to window when dynamically injected via
script tags in Extension.vue.

Solution: Changed Vite build format from IIFE to UMD, which automatically
handles global object detection (globalThis/window/self) and ensures
proper exposure in all browser contexts.

Changes:
- Updated vite.config.ts to use UMD format instead of IIFE
- Rebuilt frontend assets with correct UMD wrapper
- UMD provides better compatibility for dynamic script injection

This ensures window.ATestPlugin is properly available for Extension.vue
to mount the plugin UI.
The UMD build was failing in browser with "process is not defined" error
because Vue/Vite code references process.env.NODE_ENV.

Solution:
- Add Rollup output.intro to inject process polyfill at UMD start
- Polyfill defines: var process = { env: { NODE_ENV: "production" } }
- This prevents ReferenceError when plugin loads in browser

This allows window.ATestPlugin to be properly defined and the plugin UI
to load successfully.
## Chat Interface Improvements

- Added user/AI avatars with gradient icons
- Improved message layout with proper left/right alignment
- Smooth fade-in animations for messages
- Dark-themed SQL code blocks with better contrast
- Optimized spacing and padding throughout
- Added gradient background for chat area

## Settings Panel Redesign
- Reorganized into tabs: Local Services vs Cloud Services
- Local tab: Ollama configuration with endpoint and models
- Cloud tab: OpenAI and DeepSeek with radio selection
- Card-based provider UI with icons and descriptions
- Conditional field display (API Key only for cloud services)
- Provider-specific form fields with collapse animations
- Visual indicators for selected providers
- Enhanced model selection with size info

## Input Area Polish
- Rounded input box with focus effects
- Gradient button with hover animations
- Box shadows and modern styling
- Better visual hierarchy

## Technical Changes
- New icon imports from Element Plus
- Tab navigation with computed active state
- Collapse transitions for better UX
- Improved CSS organization and deep selectors
- Enhanced responsive layouts

This update transforms the plugin from basic functionality to a
polished, production-ready interface that clearly distinguishes
local and cloud AI services.
- Replace single availableModels ref with modelsByProvider map
- Use computed property to expose models for current provider
- Add model validation when switching providers
- Auto-select appropriate model when switching if needed
- Return detailed result object from testConnection with message and error
- Update handleTestConnection to return full result instead of boolean
- Display helpful error messages and troubleshooting tips for Ollama
- Show errors for 5 seconds for better readability
OpenAI models:
- Add GPT-5 series (gpt-5, gpt-5-mini, gpt-5-nano)
- Add GPT-4.1 series with version dates
- Add GPT-4o series with version dates
- Organize models in option groups

DeepSeek models:
- Add deepseek-reasoner as recommended model
- Reorder models with reasoner first
Prevent "[object Object] is not valid JSON" error by checking
the type before attempting to parse. The meta field could already
be parsed as an object by callAPI function.
- Add empty state with icon and message when no conversations
