BigCommerce Storefront Data Hooks
This project is under active development, new features and updates will be continuously added over time
UI hooks and data fetching methods built from the ground up for e-commerce applications written in React, that use BigCommerce as a headless e-commerce platform. The package provides:
- Code splitted hooks for data fetching using SWR, and to handle common user actions
- Code splitted data fetching methods for initial data population and static generation of content
- Helpers to create the API endpoints that connect to the hooks, very well suited for Next.js applications
