• Initializing Hotjar (use it at the very top of your application)

import * as React from 'react';
import useHotjar from 'react-use-hotjar';

const myCustomLogger = console.info;

const HotjarReadyApp = () => {
  const { initHotjar } = useHotjar();

  React.useEffect(() => {
    initHotjar(1234567, 6, false, myCustomLogger);
  }, [initHotjar]);

  return <App />;
};

• Identifying Users (Use it wherever user's information is available. Send and object respecting Identify API's rules)

import * as React from 'react';
import useHotjar from 'react-use-hotjar';

const myCustomLogger = console.log;

const MyCustomComponent = () => {
  const { identifyHotjar } = useHotjar();

  const handleUserInfo = (userInfo) => {
    const { id, ...restUserInfo } = userInfo;

    identifyHotjar(id, restUserInfo, myCustomLogger);
  };
};
