JSGI Middleware Adapter for Node.js

This package, `jsgi-node`, functions as an adapter to execute JSGI (JavaScript Gateway Interface) middleware within the Node.js environment. It specifically implements the JSGI 0.3 specification, which includes support for promise-based asynchronous operations, aligning with Node.js's non-blocking I/O model. JSGI is an asynchronous middleware interface conceived with design principles akin to WSGI in Python or Rack in Ruby, promoting straightforward and efficient middleware connectivity through JavaScript closures. While `jsgi-node` itself does not bundle JSGI components, it provides the runtime necessary for existing JSGI middleware stacks, often found in older projects such as Pintura. The package, currently at version 0.3.3, received its last significant updates over a decade ago. It is considered an abandoned project, primarily of historical interest, and is generally unsuitable for contemporary Node.js application development due to its reliance on an outdated CommonJS draft specification.
