How convert to ts

injectIntl.ts

interface InjectedIntlProps {
    intl: InjectedIntl;
}

interface InjectIntlConfig {
    intlPropName?: string;
    withRef?: boolean;
}

function injectIntl<P>(component: React.ComponentType<P & InjectedIntlProps>, options?: InjectIntlConfig):
        React.ComponentClass<Pick<P, Exclude<keyof P, keyof InjectedIntlProps>>> & { WrappedComponent: React.ComponentType<P & InjectedIntlProps> };

withTranslate.js

import React from 'react';
import PropTypes from 'prop-types';
import { injectIntl } from 'react-intl';

export function withTranslate(Component) {
  function WithTranslate(props) {
    const { intl, ...compProps } = props;
    const translate = key => {
      return intl.formatMessage({
        id: key
      });
    };

    return <Component {...compProps} t={translate} locale={intl.locale} />;
  }

  WithTranslate.displayName = `withTranslate(${Component.displayName ||
    Component.name}`;
  WithTranslate.propTypes = {
    intl: PropTypes.shape({
      locale: PropTypes.string.isRequired,
      formatMessage: PropTypes.func.isRequired
    }).isRequired
  };
  return injectIntl(WithTranslate);
}
