In this post, you will learn how to add Velo code to create a custom ecommerce product list page in Wix Studio, Editor X & Classic Editor.

import wixData from "wix-data";

let categoryFilter;
let priceFilter;

$w.onReady(() => {
  bindItemReadyForProductsRepeater();
  populateProductsRepeater();
  populateCategoriesDropdown();
  $w("#categoriesDropdown").onChange(handleCategoryFilterChange);
  $w("#minPriceDropdown, #maxPriceDropdown").onChange(handlePriceRangeFilter);
  $w("#clearButton").onClick(clearFilters);
  $w("#sortDropdown").onChange(handleSort);
});

async function getProducts() {
  let productsQuery = wixData.query("Stores/Products");

  if (categoryFilter) {
    productsQuery = productsQuery.and(categoryFilter);
  }
  if (priceFilter) {
    productsQuery = productsQuery.and(priceFilter);
  }
  if (sortBy) {
    productsQuery = applySort(productsQuery, sortBy);
  }

  const productsQueryResult = await productsQuery.find();

  console.log("products", productsQueryResult.items)

}

  }

}

  $w("#productsRepeater").onItemReady(($item, itemData) => {

    }
    $item("#price").text = `${itemData.discountedPrice} ${itemData.currency}`;
    $item("#originalPrice").text = itemData.formattedPrice;
  });
}

async function populateProductsRepeater() {

    .query("Stores/Products")

  populateProductsRepeater();
}

async function handlePriceRangeFilter() {
  const minPrice = Number($w("#minPriceDropdown").value);
  const maxPrice = Number($w("#maxPriceDropdown").value);

  const minPriceQuery = wixData.query("Stores/Products").ge("price", minPrice);
  const maxPriceQuery = wixData.query("Stores/Products").le("price", maxPrice);

  priceFilter = wixData.query("Stores/Products");

  if (minPrice) {
    priceFilter = priceFilter.and(minPriceQuery);
  }

  if (maxPrice) {
    priceFilter = priceFilter.and(maxPriceQuery);
  }

  populateProductsRepeater();
}

function clearFilters() {
  $w("#categoriesDropdown, #minPriceDropdown, #maxPriceDropdown, #sortDropdown").value = null;
  $w(
    "#categoriesDropdown, #minPriceDropdown, #maxPriceDropdown, #sortDropdown"
  ).resetValidityIndication();

  populateProductsRepeater();
}

async function handleSort() {

}
