You can use this template:

import React from 'react';
import { PageContainer } from '@ant-design/pro-layout';
import { Card, Typography } from 'antd';
import { useHistory, useIntl, useModel } from 'umi';
import styles from '../global.less';

export default (): React.ReactNode => {
  const intl = useIntl();
  const { initialState } = useModel('@@initialState');
  const history = useHistory();

  return (
    <PageContainer className={styles.container}>
      <Card>
        <Typography.Text>Hello, World</Typography.Text>
      </Card>
    </PageContainer>
  );
};
