SharePoint Authentication Configuration Builder

node-sp-auth-config is a utility package designed to simplify the creation and management of authentication configuration files for the node-sp-auth library, which handles unattended HTTP authentication to SharePoint from Node.js applications. It provides a wizard-like interactive CLI experience (`sp-auth`) and a programmatic API for building authentication options. The library supports a wide range of SharePoint versions, including SharePoint Online, 2019, 2016, 2013, and 2010, along with various authentication methods such as user credentials (SAML/ADFS, NTLM), Add-In Only permissions, and Form-Based Authentication. By default, it encrypts sensitive data like passwords using a machine-bound hash. The current stable version is 3.0.5 and it regularly releases updates in conjunction with its core dependency, node-sp-auth. Its primary differentiator is streamlining the often complex setup of SharePoint authentication credentials into a guided, persistent configuration process.
