Alpine

Alpine is attribute-driven, so the script-tag build is the natural fit. No bundler, no install.

index.html

<script src="https://cdn.thepulseapi.com/sdk/v0/pulse.iife.js"></script>
<script>
  Pulse.init({ apiKey: 'pk_live_...', organizationId: 'org_...' });
</script>

The global Pulse is the client, so call it directly from Alpine:

<div x-data="{ sku: 'sku-123' }">
  <button x-on:click="Pulse.track([{ type: 'product_view', value: sku }])">
    View
  </button>

  <button x-on:click="Pulse.track([{ type: 'add_to_cart', value: sku }])">
    Add to cart
  </button>
</div>

There is no default export on the global. Pulse.init resolves; Pulse.default.init does not.
