Frontend API

Swell.js is a universal JavaScript SDK for Swell's Frontend API, providing helper methods for common data and actions needed to create storefronts and checkout flows.

The SDK implements a subset of operations available in the Backend API and is authorized with a public key and session token, so it's safe to use in any context.

  • Fetch products, categories, store settings, nav menus, and custom content
  • Create, recover, and update shopping carts
  • Build custom checkout and subscription flows
  • Authenticate customers and allow them to edit account details, orders, and subscriptions
  • Resolve linked content to dynamically generate page URLs
  • Format prices in the store's currency
