How can I successfully retrieve all product data from a Shopify store?

[tima4ka1]

Hey!

I am creating an application and at the moment I am trying to get all product data from the store, but the function does not work for me.

I am making a request for this feature, but in the response I have no 'link' at all. And there is no other replacement that would link to the next page.

function makeRequest(nextLink = 'https : //myshopname. myshopify. com/admin/api/2021-04/products.json?limit=1') {

   return new Promise((resolve, reject) => {

      console.log(nextLink);

      fetch(nextLink).then(r => {

      const headerLink = r.headers.get('link');

      console.log(r.headers);

      console.log(headerLink);

      const match = headerLink.match(/<[^;]+\/(\w+\.json[^;]+)>;\srel="next"/);

      const nextLink = match ? match[1] : false;

      if (nextLink) {

          makeRequest(nextLink)

      } else {

         resolve();

      }

      })

   })

}

I also looked and I get an error:

status: 401,
statusText: 'Unauthorized',

Can you help me figure out how I can make this function work and how can I get all the data from this store?
