Scrap data from script tag by cheerio-CodePudding

how can I scrap data from string like this <script type="application/json" data-component-name="ItemPriceHeading">{"price":"29.0","discountedPrice":null,"offerPrice":null,"totalPrice":"29.0","currency":"PLN"}</script>

I need scrap "price" and "currency" values, but I cant understand how to do it. Thanks

I can scrap all string , but how extract only selected parameters

You can just select the <script> tag with cheerio and then get the text and parse it like json:

Here is an example:

const cheerio = require("cheerio");
const $ = cheerio.load(
    `<script type="application/json"  data-component-name="ItemPriceHeading">{"price":"29.0","discountedPrice":null,"offerPrice":null,"totalPrice":"29.0","currency":"PLN"}</script>`
);
const myJSON = JSON.parse(
    $('script[data-component-name="ItemPriceHeading"]').text()
);
console.log(myJSON);

myJSON variable should be equal to:

{
  price: '29.0',
  discountedPrice: null,
  offerPrice: null,
  totalPrice: '29.0',
  currency: 'PLN'
}
