🎯 Usage Examples

Customer Support Chat

function SupportPage() {
	return (
		<div>
			<header>Customer Support</header>
			<main>Your support content...</main>

			<ChatSDK
				userId={currentUser.id}
				authToken={authToken}
				config={{
					mode: "floating",
					showHelpChat: true,
					theme: {
						mode: "light",
						primaryColor: "#059669", // Green for support
						background: "#ffffff",
					},
				}}
			/>
		</div>
	);
}

Dark Theme Chat

function DarkChatApp() {
	return (
		<div className="dark">
			<ChatSDK
				userId="user123"
				authToken="token"
				config={{
					mode: "full",
					showHelpChat: false,
					theme: {
						mode: "dark",
						primaryColor: "#8b5cf6", // Purple
						background: "#0f172a",
					},
				}}
			/>
		</div>
	);
}

Custom Brand Colors

function BrandedChat() {
	return (
		<ChatSDK
			userId="user123"
			authToken="token"
			config={{
				mode: "floating",
				showHelpChat: true,
				theme: {
					mode: "light",
					primaryColor: "#dc2626", // Red brand color
					background: "#fefefe",
				},
			}}
		/>
	);
}

🔧 Integration with Backend

The SDK is UI-only and uses mock data by default. To integrate with your backend:

1. Replace ChatProvider with your own context
2. Connect message handlers to your API
3. Add real-time updates with WebSocket or polling
4. Implement authentication in your app

Example integration:

// Custom provider with real API
function CustomChatProvider({ children, theme }) {
	const [messages, setMessages] = useState([]);
	const [conversations, setConversations] = useState([]);

	const sendMessage = async (content) => {
		const response = await fetch("/api/messages", {
			method: "POST",
			body: JSON.stringify({ content }),
			headers: { Authorization: `Bearer ${authToken}` },
		});
		const newMessage = await response.json();
		setMessages((prev) => [...prev, newMessage]);
	};

	return (
		<ChatContext.Provider
			value={{
				messages,
				conversations,
				sendMessage,
				// ... other values
			}}
		>
			{children}
		</ChatContext.Provider>
	);
}

🎨 Customization

Styling with Tailwind

The SDK uses Tailwind CSS classes that you can override:

/* Custom styles */
.tjchatjs-floating-button {
	@apply shadow-2xl;
}

.tjchatjs-message-bubble {
	@apply rounded-xl;
}

Theme Variables

Customize CSS variables for advanced theming:

:root {
	--tjchatjs-primary: #3a8289;
	--tjchatjs-background: #ffffff;
	--tjchatjs-text: #1f2937;
}

📋 TypeScript Support

Full TypeScript support with exported types:

import {
	ChatSDK,
	ChatUser,
	ChatMessage,
	ChatConversation,
	ChatTheme,
	ChatConfig,
} from "tjchatjs";

// Use types in your code
const user: ChatUser = {
	id: "user123",
	name: "John Doe",
	avatar: "https://example.com/avatar.png",
	isOnline: true,
};
