Technical Details

Tab Switching

Uses React state to track active tab:

const [ activeTab, setActiveTab ] = React.useState( 'chat' );

Auto-Scroll Implementation

Uses refs and useEffect:

const messagesContainerRef = React.useRef( null );

React.useEffect( () => {
    if ( messagesContainerRef.current ) {
        const container = messagesContainerRef.current;
        container.scrollTop = container.scrollHeight;
    }
}, [ messages, isLoading ] );

Timeline Updates

Timeline entries update in-place instead of creating new entries:

setMessages( prev => {
    const newMessages = [ ...prev ];
    const lastTimelineIndex = newMessages.findIndex( m => m.type === 'timeline' && m.status !== 'complete' );
    if ( lastTimelineIndex !== -1 ) {
        newMessages[lastTimelineIndex] = {
            ...newMessages[lastTimelineIndex],
            status: data.status,
            message: data.message,
            icon: data.icon
        };
    }
    return newMessages;
} );
