Fetch all products by a tag with Shopify Graphql

[coderapper]

Hi Everyone,

This is not related to any specific issue. I've been using Shopify-api-node for a few of my projects and one of the challenges was to be able to find all products that have a specific tag with a graphql query. So while I was doing that I couldn't able to find any specific documentation on how to paginate the results with shopify-api-node s graphql query. After a few attempts, I was able to paginate the results with following simple async function, so I thought it would be a good idea to share the solution here which others may find helpful since I saw multiple threads around this topic. here it is !

const query = `query($cursor: String){
    products(first: 250, after:$cursor, query: "tag:tag_name") {
        pageInfo {
            hasNextPage
          }
          edges {
            cursor
            node {
              id
              tags
            }
        }
    }
  }
`
​
(async () => {
    let hasNextPage = false;
    let lastedge;
    let variable;
    do {
      await shopify.graphql(query,variable).then((product) => {
        counter = counter + 1;
        const products = Object.values(product.products.edges);
        for (const product of products) {
            let id = product.node.id.split('/').slice(-1)[0];
            counter = counter + 1; // to count the number of prodcuts 
            console.log(counter +"=>" +id+ "=>" +product.node.tags);
        }
        var last_key = product.products.edges.length;
        lastedge = product.products.edges[last_key - 1].cursor;
        hasNextPage = product.products.pageInfo.hasNextPage;
        variable = {"cursor": lastedge};
      });       
    } while (hasNextPage == true);
  })().catch(console.error);

Cheers!

You are a legend!

The issue is that the result is not an exact match. When you need to fetch products with tag "test", it will also fetch products with tag "test 2".
