import * as ReactDOM from "react-dom";

function App() {
    const currentUserModel: UserModel = {
        id: "user1",
        user: "Albert"
    };

    const otherUserModel: UserModel = {
        id: "user2",
        user: "Michale Suyama"
    };

    return (
        <ChatUIComponent user={currentUserModel} headerText="Chat Support">
            <MessagesDirective>
                <MessageDirective text="Hello, how can I help?" author={currentUserModel} />

Common Patterns

Create a Support Chat Interface

<ChatUIComponent 
  user={currentUser}
  headerText="Support Chat"
  enableAttachments={true}
  showTimeStamp={true}
  showHeader={true}
  messageToolbarSettings={{ items: ['Copy', 'Reply', 'Delete'] }}
>
  <MessagesDirective>
    {/* messages populate here */}
  </MessagesDirective>
</ChatUIComponent>

Add Message Dynamically

const chatRef = useRef<ChatUIComponent>(null);

const addNewMessage = () => {
  chatRef.current.addMessage({
    author: userModel,
    text: "Your message here",
    timeStamp: new Date()
  });
};

Configure Multiple Templates

Implement messageTemplate, emptyChatTemplate, timeBreakTemplate, and suggestionTemplate for complete customization.
