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.
The preload script (src/electron/preload.js) was removed as part of a refactor to
separate web and electron builds. This script was previously responsible for:
- Secure IPC communication between electron main and renderer processes
- SQLite database access bridge for the renderer process
- Context isolation and API exposure for electron-specific features
Current state:
- Web app builds successfully without preload script
- Electron builds fail due to missing preload script
- SQLite initialization works in main process but renderer can't access it
- Database operations fail with "Cannot read properties of undefined"
This commit is a breaking change for electron builds. The preload script will need
to be recreated to restore electron database functionality.
Affected files:
- Deleted: src/electron/preload.js
- Modified: src/main.electron.ts (removed DatabaseManager import)
- Modified: src/utils/logger.ts (simplified logging implementation)
- Modified: src/types/electron.d.ts (updated ElectronAPI interface)
- Modified: src/types/global.d.ts (updated window.electron type definition)
Next steps:
- Recreate preload script with proper SQLite bridge
- Update electron build configuration
- Restore database access in renderer process
- 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
- Remove worker thread approach in favor of direct plugin initialization
- Initialize CapacitorSQLiteElectron in main process
- Set up IPC handler to forward SQLite operations
- Remove unused worker files and build config
This reverts to a simpler, more reliable approach for SQLite in Electron,
using the plugin as intended in the main process.
- 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
Split monolithic vite.config.mjs into separate config files:
- vite.config.web.mts
- vite.config.electron.mts
- vite.config.capacitor.mts
- vite.config.pywebview.mts
- vite.config.common.mts
- vite.config.utils.mts
Updates:
- Modify package.json scripts to use specific config files
- Add electron-builder as dev dependency
- Update electron build configuration
- Fix electron resource paths
- Remove old vite.config.mjs and utils.js
This change improves maintainability by:
- Separating concerns for different build targets
- Making build configurations more explicit
- Reducing complexity in individual config files
