withLightbotMessenger HOC

Lightbot.js provides a React HOC which can be used to provide a communication interface to your React components.

withLightbotMessenger<ComponentProps>(options: { agentId: string; hostURL: string; })(Component)

How to use

React components are exported from lib/lightbot-react.

import {
  LightbotMessage,
  LightbotMessengerDecoratedProps,
  withLightbotMessenger
} from "lightbot/lib/lightbot-react";

type AppProps = LightbotMessengerDecoratedProps & {
  children: any;
}

class AppDisconnected extends Component<AppProps, {}> {
  public render() {
    const { messages, isMessengerOpen, toggleMessenger } = this.props;
    return (
      <>
        {
          isMessengerOpen ? 
          (<ChatWindow
            messages={messages}
            onMessageSend={this.sendMessage}
          />) : 
          null
        }
        <button onClick={toggleMessenger}>
          {isMessengerOpen ? "close" : "open"}
        </button>
      </>
    );
  }

  private sendMessage = (message: string) => {
    this.props.sendMessage({ type: "plain", label: message });
  }
}

export const App = withLightbotMessenger<AppProps>({
  hostURL: "https://localhost:9000",
  agentId: "agent-id"
})(AppDisconnected);

Live Example

Injected props

withLightbotMessenger injects the same props as the one defined by the Lightbot API except the onChange is implemented in order to update your React components when any update is available.
