How to use the react-helmet.default function in react-helmet

const Helmet = require('react-helmet').default;

const projectShape = require('./projectshape.jsx').projectShape;

const Meta = props => {
    const {title, instructions, author} = props.projectInfo;

    // Do not want to render any meta tags unless all the info is loaded
    // Check only author (object) because it is ok to have empty string instructions
    if (!author) return null;

    const truncatedInstructions = instructions.split(' ')
        .slice(0, 50)
        .join(' ');
