Node.js SOAP Client and Server

Node-SOAP is a robust and minimal JavaScript library designed for interacting with SOAP web services, offering both client-side and server-side functionalities. Currently at stable version 1.9.1, the project maintains a regular release cadence focused on dependency updates, security patches, and minor enhancements, typically releasing new versions every few weeks or months. Its key differentiators include comprehensive support for various SOAP security mechanisms such as BasicAuth, WS-Security, and NTLM, and a flexible API that supports both callback-based and modern promise-based interactions with WSDL-defined services. The library ships with TypeScript types, making it well-suited for contemporary Node.js applications. It targets Node.js versions 20.19.0 and higher.
