TCollectionService<T extends TWriteableId, API extends TFirestoreApi<T>> class abstract

A service for managing a collection of Firestore documents with synchronized local state.

The TCollectionService provides a robust foundation for managing collections of documents that need to be synchronized between Firestore and local state. It handles:

  • Local state management with optimistic updates
  • Remote state synchronization
  • Batch operations
  • Transaction support
  • Error handling
  • Automatic user authentication state sync

Type Parameters:

  • T - The document type, must extend TWriteableId
  • API - The Firestore API type, must extend TFirestoreApi

Example:

class UserService extends TurboCollectionService<User, UserApi> {
  UserService({required super.api});

  Future<void> updateUserName(String userId, String newName) async {
    final user = findById(userId);
    final updated = user.copyWith(name: newName);
    await updateDoc(doc: updated);
  }
}

Features:

  • Automatic local state updates before remote operations
  • Optimistic UI updates with rollback on failure
  • Batch operations for multiple documents
  • Transaction support for atomic operations
  • Automatic stream update blocking during mutations
  • Error handling and logging
  • User authentication state synchronization
