Very slow response time with shopify-api-node

Questions and Answers Strapi Backend

System Information
  • Strapi Version: 3.4.5
  • Operating System: mac OS Big Sur 11.1
  • Database: mySQL
  • Node Version: 14.5.1
  • NPM Version: 6.14.8
  • Yarn Version: 1.22.10

I followed the tutorial of this video. Basically, data from Shopify gets added to the strapi API. I implemented it my find() Controller like this:

  async find(ctx) {
    let entities;
    if (ctx.query._q) {
      entities = await strapi.services.product.search(ctx.query);
    } else {
      entities = await strapi.services.product.find(ctx.query);
    }

    for (entity of entities) {
      try {
        await shopify.product.get(entity.shopifyId).then((product) => {
          entity.shopify = {
            id: product.id,
            product_type: product.product_type,
            admin_graphql_api_id: product.admin_graphql_api_id,
            variants: product.variants
          };
        });
      } catch (e) {
        console.log(e);
      }
    }
    return entities.map(entity => sanitizeEntity(entity, {model: strapi.models.product}));
  },

But now, as there a some more products in shopify (34 products), every GET-Request of /products is very very slow. They take up to 15.000 miliseconds. Is there a way to improve the speed?

Thanks in Advance!
