datum 0.0.9

A powerful, offline-first data synchronization engine for Flutter and Dart, featuring relational data support, real-time queries, and intelligent conflict resolution.

0.0.9

✨ Features

Core

• Implement Sync Request Strategies: Introduced a new system to control how concurrent calls to the synchronize method are handled, preventing race conditions and improving data consistency.
  • Added DatumSyncRequestStrategy as the base for defining execution behavior.
  • Implemented SequentialRequestStrategy to queue and process all synchronize calls in the order they are received. This is the new default behavior.
  • Implemented SkipConcurrentStrategy as an alternative strategy to ignore new synchronize calls if a sync is already in progress.
  • Added syncRequestStrategy to DatumConfig to allow global configuration of this behavior.
  • Added an isSyncing getter to DatumSyncEngine to check the current sync status.

🐛 Bug Fixes

Build

• Correct Conditional Imports: Fixed conditional imports to ensure compatibility across both dart:io and dart:html environments.

0.0.8

• fix conditional import for web and io

0.0.7

🐛 Bug Fixes

• 🐛 Isolate Error Handling & Web Compatibility:
  • Ensured errors during isolate operations are properly caught and sent back to the main thread.
  • Enhanced web compatibility by using compute function for isolate operations.
  • Removed unnecessary newline at end of file for consistency.
  • Removed unused import in supabase_security_dialog.dart.

0.0.6

🚀 Features

• 🚀 Isolate Sync Strategy: Introduced a new IsolateStrategy that runs data synchronization in a background isolate for improved performance and UI responsiveness. This includes platform-specific runners for both mobile/desktop (dart:io) and web (dart:html) via conditional imports, ensuring broad platform support.
• ✨ Sealed Class Migration: Migrated DatumEntity and RelationalDatumEntity to a DatumEntityBase sealed class for enhanced type safety and to remove the need for sampleInstance.
• 🚀 New Facade Methods: Added a suite of new methods to the global Datum facade for easier data interaction:
  • Reactive Watching: watchAll, watchById, watchQuery, watchRelated.
  • One-time Fetching: query, fetchRelated.
  • Data & Sync Management: getPendingCount, getPendingOperations, getStorageSize, watchStorageSize, getLastSyncResult, checkHealth.
  • Sync Control: pauseSync, resumeSync.

✅ Tests

• 🧪 Enhanced Core Tests: Added test cases for uninitialized state errors, statusForUser, allHealths, and relational method behavior. Introduced a CustomManagerConfig for easier mock manager injection in tests.

♻️ Refactors & 🧹 Chores

• ♻️ Isolate Helper Improvements:
  • Replaced conditional imports with platform-specific implementations.
  • Removed isolate_helper.dart and isolate_helper_unsupported.dart.
  • Added _isolate_helper_io.dart for IO platforms.
  • Updated _isolate_helper_web.dart to use synchronous JSON encoding.
  • Updated datum_sync_engine.dart to use the new isolate helper.
  • Removed unused imports in test.dart, adapter_test.dart, relational_data_test.dart, relational_data_integration_test.dart, mock_adapters.dart, and test_entity.dart.
  • Updated isolate_helper_test.dart to use the new isolate helper.
• 🗑️ Removed sampleInstance: The sampleInstance property on LocalAdapter is no longer needed due to the sealed class migration and has been removed.
• 🩺 Renamed AdapterHealthStatus.ok to AdapterHealthStatus.healthy for better clarity.
• 📦 Refactored internal imports to use the datum package consistently.
• ⚙️ Made MigrationExecutor generic to improve type safety during migrations.
• 🗺️ Added DataSource enum to explicitly specify the source for query operations.
