This commit updates the Electron preload script and type definitions to improve
SQLite integration and IPC communication. The changes include:
- Enhanced preload script (electron/src/preload.ts):
* Added detailed logging for SQLite operations and IPC communication
* Implemented retry logic for SQLite operations (3 attempts, 1s delay)
* Added proper type definitions for SQLite connection options
* Defined strict channel validation for IPC communication
* Improved error handling and logging throughout
- Updated type definitions (src/types/electron.d.ts):
* Aligned ElectronAPI interface with actual implementation
* Added proper typing for all SQLite operations
* Added environment variables (platform, isDev)
* Structured IPC renderer interface with proper method signatures
Current Status:
- Preload script initializes successfully
- SQLite availability check works (returns true)
- SQLite ready signal is properly received
- Database operations are failing with two types of errors:
1. "CapacitorSQLite not available" during initialization
2. "Cannot read properties of undefined" for SQLite methods
Next Steps:
- Verify context bridge exposure in renderer process
- Check main process SQLite handlers
- Debug database initialization
- Address Content Security Policy warning
Affected Files:
- Modified: electron/src/preload.ts
- Modified: src/types/electron.d.ts
Note: This is a transitional commit. While the preload script and type
definitions are now properly structured, database operations are not yet
functional. Further debugging and fixes are required to resolve the
SQLite integration issues.
- Assign CapacitorSQLite instance to the global sqlitePlugin variable so it is accessible in IPC handlers.
- Enhance error logging in the IPC handler to include JSON stringification and stack trace for better debugging.
- Reveal that the generic .handle() method is not available on the plugin, clarifying the next steps for correct IPC wiring.
- Added "type": "module" to package.json to support ES module imports for Electron SQLite
- Renamed postcss.config.js to postcss.config.cjs to maintain CommonJS syntax
- This ensures build tools can properly load the PostCSS configuration
- Changed from direct plugin usage to SQLiteConnection pattern
- Matches how platform services use the SQLite plugin
- Removed handle() method dependency
- Added proper method routing in IPC handler
The app now launches without initialization errors. Next steps:
- Test actual SQLite operations (createConnection, query, etc.)
- Verify database creation and access
- Add error handling for database operations
- Enhance electron build configuration with proper asset handling
- Add comprehensive logging and error tracking
- Implement CSP headers for security
- Fix module exports for logger compatibility
- Update TypeScript and Vite configs for better build support
- Improve development workflow with better dev tools integration
- Add web build prerequisite step to electron build docs
- Update electron run command to use npx
- Fix electron asset loading with improved path handling
- Add request interception for proper asset resolution
- Remove service worker files from electron build
- Improve debug logging for electron builds
- Properly disable service workers in electron builds
- Add CSP headers for electron security
- Fix path resolution in electron context
- Improve preload script error handling and IPC setup
- Update build scripts for better electron/capacitor compatibility
- Fix router path handling in electron context
- Remove electron-builder dependency
- Streamline build process and output structure
This change improves the stability and security of electron builds while
maintaining PWA functionality in web builds. Service workers are now
properly disabled in electron context, and path resolution issues are
fixed.
- Add extraResources config to package.json to properly include www directory
- Update path rewriting in build-electron.js to handle all asset types
- Fix modulepreload and stylesheet paths in index.html
- Improve path handling in main.js for packaged app
- Clean up file protocol handling and service worker management
This fixes the issue with assets not loading in the packaged Electron app
by ensuring all paths are correctly rewritten to reference the www directory
in the app resources.
- Add dedicated electron build scripts for each platform
- Configure Vite rollup options for electron builds
- Update electron-builder configuration with proper app metadata
- Add clean script and rimraf dependency
- Set proper appId and build settings for production builds
- Enable asar packaging for better security
