Headless cart icon

Experiment #1066th April, 2021by Joshua Nussbaum

After building a headless buy button and add to cart button, the next stop is a cart icon.

The cart icon displays the total number of items in the cart, and acts as a button the user can click to view their cart and initiate the checkout.

Using the cart icon component would look like this:

    <!-- svg icon here (optional) -->


Implenting the <cart-icon> component is fairly straight-forward, since we’re already exporting a derived store called count:

<svelte:options tag="cart-icon"/>

  // import the derived store
  import {count} from './cart'

  function click() {
    // open cart view

<button class:empty={$count == 0} on:click={click}>
  <span class="count">{$count}</span>
