Add ld+json script tag in client-side React

For me, React Helmet works well.

<Helmet>
    <script className="structured-data-list" type="application/ld+json">{structuredJSON}</script>
</Helmet> 

Where structuredJSON is something like result of such function:

export const structuredDataSingle = (prod, imgPath, availability) => {

    let data = {
        "@context": "http://schema.org/",
        "@type": "Product",
        "name": `${prod.title}`,
        "image": prod.images.map((item) => imgPath + item),
        "description": prod['description'],
        "url": location.href,
        "offers": {
            "@type": "Offer",
            "priceCurrency": `${prod['currency'] || "₴"}`,
            "price": prod['price'] ? `${parseFloat(prod['price'])}` : 0,
            "availability": `${availability}`,
            "seller": {
                "@type": "Organization",
                "name": "TopMotoPro"
            }
        }
    };

    // brand
    if(prod['brand']) {
        data['mpn'] = prod['brand'];
        data['brand'] = {
            "@type": "Thing",
            "name": `${prod['brand']}`
        };
    }

    // logo
    if(prod['logo']){
        data['logo'] = imgPath + prod['logo'];
    }

    return JSON.stringify(data);
};
