Xero Node.js SDK (OAuth 2.0 Client)

The xero-node SDK provides a comprehensive client for interacting with the Xero APIs (Accounting, Assets, Bankfeeds, Files, Projects, Payroll AU/NZ/UK) using Node.js. It facilitates OAuth 2.0 authentication and API requests, simplifying integration for developers building applications that connect with Xero accounting data. The library is currently in its 15.0.0 major version, with frequent updates (multiple minor/patch releases per month, and major releases roughly every few months) to reflect changes in the underlying Xero API and add new features. Key differentiators include full API coverage across multiple Xero API sets and robust TypeScript support, making it suitable for enterprise-grade integrations requiring strong typing and reliability.
