Hook Usage

import { useBroadcastClient } from './hooks/useBroadcastClient';

function App() {
  const { messages, unreadCount, markRead, markDismissed } = useBroadcastClient({
    pollingInterval: 60000
  });

  return (
    <div>
      {messages.map(msg => (
        <Banner
          key={msg.id}
          title={msg.title}
          body={msg.body}
          onDismiss={() => markDismissed(msg.id)}
          onClick={() => markRead(msg.id)}
        />
      ))}
    </div>
  );
}

Provider Pattern

// BroadcastProvider.tsx
import { createContext, useContext, useEffect, useState } from 'react';
import { createBroadcastClient, BroadcastClient, InAppMessage } from '@bytelyst/broadcast-client';

const BroadcastContext = createContext<BroadcastContextType | null>(null);

export function BroadcastProvider({ children, config }: { children: React.ReactNode; config: BroadcastConfig }) {
  const [client] = useState(() => createBroadcastClient(config));
  const [messages, setMessages] = useState<InAppMessage[]>([]);

  useEffect(() => {
    client.startPolling(60000, setMessages);
    return () => client.stopPolling();
  }, [client]);

  const value = {
    messages,
    unreadCount: messages.filter(m => m.status === 'unread').length,
    markRead: client.markRead.bind(client),
    markDismissed: client.markDismissed.bind(client),
    trackClick: client.trackClick.bind(client),
  };

  return (
    <BroadcastContext.Provider value={value}>
      {children}
    </BroadcastContext.Provider>
  );
}

export const useBroadcast = () => {
  const ctx = useContext(BroadcastContext);
  if (!ctx) throw new Error('useBroadcast must be used within BroadcastProvider');
  return ctx;
};

Types

interface InAppMessage {
  id: string;
  broadcastId: string;
  title: string;
  body?: string;
  style: 'banner' | 'modal' | 'fullscreen' | 'toast';
  priority: 'low' | 'normal' | 'high' | 'urgent';
  ctaText?: string;
  ctaUrl?: string;
  imageUrl?: string;
  deepLink?: {
    screen: string;
    params: Record<string, string>;
  };
  status: 'unread' | 'read' | 'dismissed';
  createdAt: string;
}

interface BroadcastConfig {
  baseURL: string;
  productId: string;
  getAuthToken: () => Promise<string>;
}

Error Handling

All methods return a result tuple [data, error]:

const [data, error] = await client.getMessages();

if (error) {
  console.error('Failed to fetch messages:', error.message);
  return;
}

// Use data.messages
