Use Cases

Manual Unread Management

Mark Conversation as Important:

// Mark conversation as having unread messages to draw attention
async function markAsImportant(userId, channelId, channelType) {
    try {
        await setUnreadCount({
            uid: userId,
            channel_id: channelId,
            channel_type: channelType,
            unread: 1
        });
        
        console.log('Conversation marked as important');
        updateUIBadge(channelId, 1);
    } catch (error) {
        console.error('Failed to mark conversation as important:', error);
    }
}

Reset Unread Count:

// Reset unread count to zero
async function resetUnreadCount(userId, channelId, channelType) {
    try {
        await setUnreadCount({
            uid: userId,
            channel_id: channelId,
            channel_type: channelType,
            unread: 0
        });
        
        console.log('Unread count reset to zero');
        updateUIBadge(channelId, 0);
    } catch (error) {
        console.error('Failed to reset unread count:', error);
    }
}

Notification Management

Custom Notification Badges:

// Set custom unread count for special notifications
async function setCustomNotification(userId, channelId, channelType, count) {
    try {
        await setUnreadCount({
            uid: userId,
            channel_id: channelId,
            channel_type: channelType,
            unread: count
        });
        
        // Update UI with custom badge
        updateNotificationBadge(channelId, count);
        
        // Show system notification if count > 0
        if (count > 0) {
            showSystemNotification(`${count} new items in ${channelId}`);
        }
    } catch (error) {
        console.error('Failed to set custom notification:', error);
    }
}

Batch Unread Operations

Batch Set Unread Counts:

// Set unread counts for multiple conversations
async function batchSetUnreadCounts(userId, conversationUpdates) {
    const results = [];
    
    for (const update of conversationUpdates) {
        try {
            await setUnreadCount({
                uid: userId,
                channel_id: update.channelId,
                channel_type: update.channelType,
                unread: update.unreadCount
            });
            
            results.push({
                channelId: update.channelId,
                success: true,
                unreadCount: update.unreadCount
            });
        } catch (error) {
            results.push({
                channelId: update.channelId,
                success: false,
                error: error.message
            });
        }
    }
    
    return results;
}

// Usage
const updates = [
    { channelId: 'group123', channelType: 2, unreadCount: 5 },
    { channelId: 'user456', channelType: 1, unreadCount: 2 },
    { channelId: 'group789', channelType: 2, unreadCount: 0 }
];

const results = await batchSetUnreadCounts('user123', updates);
console.log('Batch update results:', results);

Priority Management

Set Priority-based Unread Counts:

class ConversationPriorityManager {
    constructor(userId) {
        this.userId = userId;
        this.priorityLevels = {
            urgent: 99,
            high: 10,
            normal: 1,
            low: 0
        };
    }
    
    async setPriority(channelId, channelType, priority) {
        const unreadCount = this.priorityLevels[priority] || 1;
        
        try {
            await setUnreadCount({
                uid: this.userId,
                channel_id: channelId,
                channel_type: channelType,
                unread: unreadCount
            });
            
            // Update UI with priority styling
            this.updatePriorityUI(channelId, priority, unreadCount);
            
            console.log(`Set ${channelId} priority to ${priority} (unread: ${unreadCount})`);
        } catch (error) {
            console.error(`Failed to set priority for ${channelId}:`, error);
        }
    }
    
    updatePriorityUI(channelId, priority, unreadCount) {
        const element = document.querySelector(`[data-channel="${channelId}"]`);
        if (element) {
            element.className = `conversation-item priority-${priority}`;
            
            const badge = element.querySelector('.unread-badge');
            if (badge) {
                badge.textContent = unreadCount > 0 ? unreadCount : '';
                badge.style.display = unreadCount > 0 ? 'block' : 'none';
            }
        }
    }
    
    async markAsUrgent(channelId, channelType) {
        await this.setPriority(channelId, channelType, 'urgent');
    }
    
    async markAsNormal(channelId, channelType) {
        await this.setPriority(channelId, channelType, 'normal');
    }
    
    async clearPriority(channelId, channelType) {
        await this.setPriority(channelId, channelType, 'low');
    }
}

// Usage
const priorityManager = new ConversationPriorityManager('user123');

// Mark conversation as urgent
await priorityManager.markAsUrgent('group123', 2);

// Set normal priority
await priorityManager.markAsNormal('user456', 1);

// Clear priority
await priorityManager.clearPriority('group789', 2);

Sync and Recovery

Sync Unread Counts from External Source:

// Sync unread counts from external system
async function syncUnreadFromExternal(userId, externalUnreadData) {
    const syncResults = [];
    
    for (const item of externalUnreadData) {
        try {
            await setUnreadCount({
                uid: userId,
                channel_id: item.channelId,
                channel_type: item.channelType,
                unread: item.unreadCount
            });
            
            syncResults.push({
                channelId: item.channelId,
                synced: true,
                unreadCount: item.unreadCount
            });
        } catch (error) {
            syncResults.push({
                channelId: item.channelId,
                synced: false,
                error: error.message
            });
        }
    }
    
    // Log sync results
    const successful = syncResults.filter(r => r.synced).length;
    const failed = syncResults.filter(r => !r.synced).length;
    
    console.log(`Sync completed: ${successful} successful, ${failed} failed`);
    
    return syncResults;
}

Testing and Development

Test Unread Scenarios:

// Helper function for testing different unread scenarios
async function testUnreadScenarios(userId, channelId, channelType) {
    const scenarios = [
        { name: 'No unread', count: 0 },
        { name: 'Single unread', count: 1 },
        { name: 'Multiple unread', count: 5 },
        { name: 'High unread', count: 99 },
        { name: 'Max unread', count: 999 }
    ];
    
    for (const scenario of scenarios) {
        console.log(`Testing scenario: ${scenario.name}`);
        
        try {
            await setUnreadCount({
                uid: userId,
                channel_id: channelId,
                channel_type: channelType,
                unread: scenario.count
            });
            
            // Wait for UI update
            await new Promise(resolve => setTimeout(resolve, 500));
            
            // Verify UI state
            const badge = document.querySelector(`[data-channel="${channelId}"] .unread-badge`);
            const displayedCount = badge ? badge.textContent : '0';
            
            console.log(`✓ ${scenario.name}: Set ${scenario.count}, displayed ${displayedCount}`);
        } catch (error) {
            console.error(`✗ ${scenario.name}: Failed -`, error.message);
        }
    }
}

Best Practices

1. Validation: Validate unread count values (non-negative integers)
2. UI Consistency: Ensure UI updates match the set unread count
3. Error Handling: Handle API errors gracefully without breaking UI
4. Performance: Batch operations when setting multiple unread counts
5. User Experience: Use meaningful unread counts that help users prioritize
6. Sync Strategy: Implement proper sync mechanisms for unread counts
7. Testing: Test various unread count scenarios during development
