Bulkneedz is a specialized e-commerce platform for “bulk deals” related to limited sneaker releases. Developed by UNHYDE, the platform specifically creates urgency via time-limited deals and a real-time stock interface. By combining Shopify's robust e-commerce features with tailored front-end features such as countdown timers and dynamic inventory display, shopping becomes an interactive, time-critical experience.
The solution combines Shopify's standard functionality with custom JavaScript for dynamic front-end updates. Shopify provides the authoritative inventory source, while the frontend shows remaining units and time until the deal is closed in real time. This creates a seamless connection between robust backend and responsive UI.
Objective: Live countdown that automatically ends or resets when it expires. The end time is obtained from a product metafield.
technologies: Liquid (for metafield output), JavaScript (for client-side computation and rendering).
Liquid example (excerpt):
Liquid:
<!-- product.liquid or a section template -->
{%- comment -%}
We first check if the product has a metafield called `countdown_end`
in the `custom` namespace. If it exists, we assign that to `deal_end_time`.
Otherwise, we use a fallback date.
{%- endcomment -%}
{% if product.metafields.custom.countdown_end %}
{% assign deal_end_time = product.metafields.custom.countdown_end %}
{% else %}
{% assign deal_end_time = '2025-03-01 23:59:59' %}
{% endif %}
<div id="countdown-timer"
data-deal-end-time="{{ deal_end_time | date: '%Y/%m/%d %H:%M:%S' }}">
</div>
<script>
(function() {
const countdownElement = document.getElementById('countdown-timer');
const dealEndTimeStr = countdownElement.dataset.dealEndTime;
const dealEndTime = new Date(dealEndTimeStr).getTime();
function updateCountdown() {
const now = new Date().getTime();
const distance = dealEndTime - now;
if (distance <= 0) {
countdownElement.innerHTML = "Deal Closed";
// Optionally disable purchase button or handle deal closure logic
return;
}
// Calculate remaining days, hours, minutes, seconds
const days = Math.floor(distance / (1000 * 60 * 60 * 24));
const hours = Math.floor((distance % (1000 * 60 * 60 * 24))
/ (1000 * 60 * 60));
const minutes = Math.floor((distance % (1000 * 60 * 60))
/ (1000 * 60));
const seconds = Math.floor((distance % (1000 * 60))
/ 1000);
// Render in the HTML element
countdownElement.innerHTML =
`${days}d ${hours}h ${minutes}m ${seconds}s`;
}
// Update the countdown every second
setInterval(updateCountdown, 1000);
updateCountdown(); // Run once on page load
})();
</script>
product.metafields.custom.countdown_end provides the end time per product.countdown_start), a start time can be managed.
Objective: Show remaining inventory in real time and dynamically carry the progress indicator.
technologies: Liquid (initial value stocks), JavaScript (UI update via event or API feedback).
Liquid example (excerpt):
Liquid:
<!-- product.liquid or a section template -->
{% assign total_stock = product.variants.first.inventory_quantity %}
<div class="stock-container">
<p>Stock remaining: <span id="stock-remaining">{{ total_stock }}</span></p>
<div class="stock-bar" style="border: 1px solid #000; width: 100%; height: 20px;">
<div id="stock-progress" style="background: #FF4500; height: 100%; width: 0%;">
</div>
</div>
</div>
<script>
(function() {
const totalStock = parseInt("{{ total_stock }}", 10);
const stockRemainingElement = document.getElementById('stock-remaining');
const stockProgressElement = document.getElementById('stock-progress');
// Function to update the progress bar
function updateStockProgress(currentStock) {
// Calculate the percentage of stock used (or remaining)
const percentage = ((totalStock - currentStock) / totalStock) * 100;
stockProgressElement.style.width = percentage + '%';
}
// On page load, set initial progress
let currentStock = totalStock;
updateStockProgress(currentStock);
// Example: If an item is purchased, decrease the current stock by 1
// This could be triggered by a real event or an API callback
document.addEventListener('purchaseMade', function() {
currentStock -= 1;
if (currentStock < 0) currentStock = 0;
// Update UI
stockRemainingElement.innerText = currentStock;
updateStockProgress(currentStock);
});
})();
</script>
PurchaseMade), which can be triggered after checkout or AJAX purchase.
