React

The @saytv/chat-react package provides a typed React component and hook for integrating the chat widget.

Installation

npm install @saytv/chat-react

Peer dependencies: React 17+ and react-dom 17+.

Basic Usage

import { SayTVChat } from '@saytv/chat-react';

function App() {
  return (
    <SayTVChat
      appId="your-app-id"
      theme="light"
      height={700}
      width="100%"
    />
  );
}

With External Auth

import { SayTVChat } from '@saytv/chat-react';

function App() {
  const [token, setToken] = useState<string | undefined>();

  useEffect(() => {
    // Fetch your user's JWT token
    fetchUserToken().then(setToken);
  }, []);

  return (
    <SayTVChat
      appId="your-app-id"
      authToken={token}
      builtInAuth={false}
      theme="light"
      height={700}
      width="100%"
    />
  );
}

useSayTVChat Hook

The useSayTVChat hook provides imperative access to the widget:

import { SayTVChat, useSayTVChat } from '@saytv/chat-react';

function App() {
  const { chatRef, getElement, setToken, setTheme } = useSayTVChat();

  return (
    <>
      <SayTVChat
        ref={chatRef}
        appId="your-app-id"
        theme="light"
        height={700}
        width="100%"
      />

      <button onClick={() => setTheme('dark')}>Dark Mode</button>
      <button onClick={() => setToken(newToken)}>Update Token</button>
    </>
  );
}

Hook Return Values

Property	Type	Description
chatRef	RefObject<SayTVChatRef>	Pass to <SayTVChat ref={chatRef}>
getElement()	() => HTMLElement | null	Returns the underlying <saytv-chat> element
setToken(token)	(token: string) => void	Updates the auth-token attribute
setTheme(theme)	(theme: 'light' | 'dark') => void	Switches the color theme

Event Handling

function App() {
  return (
    <SayTVChat
      appId="your-app-id"
      onReady={() => console.log('Widget ready')}
      onUserLogin={(e) => console.log('Logged in:', e.detail.user)}
      onMessageSent={(e) => console.log('Sent:', e.detail.message)}
      onMessageReceived={(e) => console.log('Received:', e.detail.message)}
      onEpisodeChanged={(e) => console.log('Episode:', e.detail.episode)}
      onError={(e) => console.error('Error:', e.detail.error)}
    />
  );
}

Custom Theming

Pass CSS custom properties via the style prop:

<SayTVChat
  appId="your-app-id"
  theme="light"
  style={{
    '--stv-color-primary': '#4f46e5',
    '--stv-color-accent': '#10b981',
    '--stv-border-radius-md': '12px',
  } as React.CSSProperties}
/>

See Theming for all available CSS variables.

Localization

Set the UI language with locale and supply your own translation catalogs via translations. Catalogs are keyed by locale and merged over the built-in English, so untranslated keys fall back to English. RTL languages lay out automatically.

<SayTVChat
  appId="your-app-id"
  locale="ar"
  translations={{
    ar: {
      'auth.login.title': 'مرحبا بعودتك',
      'chat.input.placeholder': 'اكتب رسالة…',
    },
  }}
/>

Alternatively, point translationsUrl at a hosted flat JSON catalog and the widget fetches and registers it for the active locale, no object needed. A failed fetch falls back to English.

<SayTVChat
  appId="your-app-id"
  locale="ar"
  translationsUrl="https://your-cdn.com/locales/ar.json"
/>

See Localization for the full guide and available keys.
