Subbly.js SDK

Subbly.js is Subbly's browser-side JavaScript library, published on npm as @subbly/sdk. It calls the Storefront API for you, holds one cart per page, and keeps the cart ID and the customer's access token in browser cookies.

The library is browser-first. It reads and writes document.cookie directly, so run it in the browser, not on a server.

In this section

• Install — add the package from npm or load it from a CDN, then start it with Subbly.init.
• Configure — pass your API key, a cart to load and a customer to authenticate.
• Keep it up to date — pin a version and upgrade on your own schedule.
• Build a checkout — the short path from an empty cart to a paid order.
• Handle errors — read the code a failed request rejects with.
• Run a funnel — show upsell offers before, during and after checkout.
