Key Challenges
Real-time Synchronization
One of the biggest challenges was ensuring data consistency across multiple devices. I implemented optimistic updates to make the UI feel snappy while maintaining data integrity.
const updateTask = async (taskId: string, updates: Partial<Task>) => {
// Optimistic update
dispatch(taskUpdated({ id: taskId, changes: updates }));
try {
await firestore.collection('tasks').doc(taskId).update(updates);
} catch (error) {
// Revert on error
dispatch(taskUpdateFailed(taskId));
}
};
Performance Optimization
With potentially thousands of tasks, performance was critical. I implemented:
- Virtual scrolling for long task lists
- Memoization with React.memo
- Code splitting for faster initial loads
- Service workers for offline functionality
