strong-soap: Node.js SOAP Client and Server

strong-soap provides a comprehensive Node.js module for interacting with SOAP web services, offering both client capabilities for invoking services and a mock-up server for testing. Currently at version 5.0.9, it maintains an active development pace with frequent patch and minor updates, typically on a monthly or bi-monthly schedule, and major versions released approximately annually to biennially, often aligning with Node.js version support. The library is built upon the `node-soap` module and distinguishes itself by supporting both RPC and Document styles, as well as SOAP 1.1 and 1.2 Faults. It includes utility APIs for converting XML to JSON and vice versa, describing WSDL documents, and handling both synchronous and asynchronous service method calls. A key feature is its built-in WS-Security support, specifically for UsernameToken and PasswordText encoding, enhancing its utility for enterprise integrations.
