There is a minified UMD build available via CDN (see the Changelog for details about the latest release):
You can also use a specific release version:
You can also fetch the unoptimized release for a version (2.0.1 and above). This will be larger than the optimized version, as it will contain all fields that are available in the Storefront API:
The JS Buy SDK has four build versions: ES, CommonJS, AMD, and UMD.
UMD Unoptimized: This will be larger than the optimized version, as it will contain all fields that are available in the Storefront API. This should only be used when you need to add custom queries to supplement the JS Buy SDK queries.

Completing a checkout
Expanding the SDK
Not all fields that are available on the Storefront API are exposed through the SDK. If you use the unoptimized version of the SDK, you can easily build your own queries. In order to do this, use the UMD Unoptimized build.
Initializing the Client
// fetch the large, unoptimized version of the SDK;const client = Client;
// Build a custom products query using the unoptimized version of the SDKconst productsQuery = clientgraphQLClient;// Call the send method with the custom products queryclientgraphQLClient;
