BigCommerce API Client for Node.js

node-bigcommerce is a comprehensive Node.js module designed for integrating applications with the BigCommerce API. It facilitates OAuth 2.0 authentication, handles authorization flows, verifies signed payloads for app load/uninstall events, and provides convenient helper methods for executing various API requests (GET, POST, PUT, DELETE). The current stable version is 4.1.0. While the release cadence is moderate, major versions introduce breaking changes such as the significant refactor in v3.0.0 to exclusively use Promises and the dropping of older Node.js versions. A key differentiator is its streamlined approach to BigCommerce-specific authentication mechanisms and direct support for different API versions (v2 and v3). Since v3.0.0, it leverages ES6 classes and standard Promises, moving away from callback-based patterns.
