React

Install @sayless/chat and boot from a hook. The package queues commands before the per-app loader arrives, same as the vanilla JavaScript API.

import { useSayless } from '@sayless/chat';

function Chat({ appId, identityToken }: { appId: string; identityToken: () => Promise<string> }) {
  const chat = useSayless({ appId, identityToken });
  return (
    <button type="button" onClick={() => chat.open()}>
      Chat with us
    </button>
  );
}

identityToken can be a string or () => Promise<string>. Pass a function when the JWT is short-lived so the iframe can ask for a fresh one. You can still queue window.Sayless('boot', …) yourself if you are not using React. See Identity verification for signing.
