🚀 Quick Start

Option 1: Simple Chat (No Authentication Required)

Perfect for testing and simple integrations:

import React from 'react';
import { SimpleChat, SimpleUser } from 'react-firebase-chat';

const MyApp = () => {
  const currentUser: SimpleUser = {
    id: 'user-123',
    name: 'John Doe',
    avatar: 'https://example.com/avatar.jpg'
  };

  return (
    <SimpleChat
      roomId="my-chat-room"
      currentUser={currentUser}
      onSend={(messages) => console.log('Sent:', messages)}
      placeholder="Type your message..."
    />
  );
};

Option 2: Full Featured Chat (With Firebase & Context)

For production applications with full cross-platform sync:

Basic Usage

1. Initialize with ChatProvider

import React from 'react';
import { ChatProvider, ChatScreen } from 'react-firebase-chat';

const firebaseConfig = {
  apiKey: "your-web-api-key",
  authDomain: "your-project.firebaseapp.com", 
  projectId: "your-project-id",
  storageBucket: "your-project.appspot.com",
  messagingSenderId: "123456789",
  appId: "1:123456789:web:abcdef123456"
};

const currentUser = {
  _id: 'web-user-123',
  name: 'John Doe',
  avatar: 'https://example.com/avatar.jpg'
};

function App() {
  return (
    <ChatProvider 
      currentUser={currentUser} 
      firebaseConfig={firebaseConfig}
      encryptionKey="optional-encryption-key"
    >
      <ChatApp />
    </ChatProvider>
  );
}

function ChatApp() {
  const partnerInfo = {
    id: 'partner-123',
    name: 'Jane Smith',
    avatar: 'https://example.com/jane.jpg',
  };

  return (
    <ChatScreen 
      conversationId="conversation-123"
      memberIds={[partnerInfo.id]} 
      partners={[partnerInfo]}
      onSend={(messages) => console.log('Messages sent:', messages)}
      showCamera={true}
      showFileUpload={true}
      showGallery={true}
    />
  );
}

export default App;

2. Advanced Usage with Custom Components

import { ChatProvider, useChat, useChatContext } from 'react-firebase-chat';

const CustomChatApp: React.FC = () => {
  const { currentUser } = useChatContext();
  const { messages, sendMessage, loading } = useChat({
    userId: currentUser._id.toString(),
    conversationId: 'conversation-123'
  });

  const handleSendMessage = async (text: string) => {
    await sendMessage({
      text,
      user: {
        _id: currentUser._id,
        name: currentUser.name,
        avatar: currentUser.avatar,
      },
    });
  };

  return (
    <div className="custom-chat">
      {/* Your custom UI implementation */}
    </div>
  );
};
  return (
    <AuthProvider>
      <ChatProvider>
        <YourChatComponent />
      </ChatProvider>
    </AuthProvider>
  );
}

3. Use the Chat component:

import React from 'react';
import { Chat, useAuthContext } from 'react-firebase-chat';

function ChatRoom() {
  const { user } = useAuthContext();

  if (!user) {
    return <div>Please sign in to use chat</div>;
  }

  return (
    <div style={{ height: '500px' }}>
      <Chat
        roomId="general"
        currentUser={{
          uid: user.uid,
          email: user.email || '',
          displayName: user.displayName || 'Anonymous',
          photoURL: user.photoURL,
          isOnline: true,
          lastSeen: new Date(),
        }}
      />
    </div>
  );
}

Authentication

The library provides built-in authentication hooks:

import { useAuth } from 'react-firebase-chat';

function LoginForm() {
  const { signIn, signUp, loading, error } = useAuth();

  const handleSignIn = async (email: string, password: string) => {
    try {
      await signIn(email, password);
    } catch (error) {
      console.error('Sign in failed:', error);
    }
  };

  const handleSignUp = async (email: string, password: string, displayName: string) => {
    try {
      await signUp(email, password, displayName);
    } catch (error) {
      console.error('Sign up failed:', error);
    }
  };

  // Render your login form...
}

Configuration

Configure the chat behavior with the ChatProvider:

<ChatProvider
  config={{
    enableTypingIndicator: true,
    enableReadReceipts: true,
    maxMessageLength: 500,
    maxFileSize: 5 * 1024 * 1024, // 5MB
    theme: 'light'
  }}
  events={{
    onMessageSent: (message) => console.log('Message sent:', message),
    onError: (error) => console.error('Chat error:', error)
  }}
>
  <App />
</ChatProvider>

Advanced Usage

Custom Message Handling

import { useChat } from 'react-firebase-chat';

function CustomChatRoom() {
  const { messages, sendMessage, loading } = useChat('room-id', 'user-id');

  const handleSendMessage = async (text: string) => {
    await sendMessage(text);
    // Custom logic after sending
  };

  return (
    <div>
      {messages.map(message => (
        <div key={message.id}>{message.text}</div>
      ))}
    </div>
  );
}

Typing Indicators

import { useTyping } from 'react-firebase-chat';

function TypingExample() {
  const { typingUsers, setTyping } = useTyping('room-id', 'user-id');

  const handleInputChange = (value: string) => {
    setTyping(value.length > 0);
  };

  return (
    <div>
      {typingUsers.length > 0 && (
        <div>{typingUsers.map(u => u.displayName).join(', ')} typing...</div>
      )}
    </div>
  );
}
