Node Sass Middleware for Connect/Express

node-sass-middleware is a Connect/Express middleware designed to automatically recompile `.scss` or `.sass` files on demand for web servers. It leverages the `node-sass` library (which in turn uses LibSass) to provide on-the-fly compilation, caching, and debugging capabilities directly within a Node.js web application stack. The package's current stable version is 1.1.0, with its latest patch release (v1.1.0) occurring in 2024. While the package itself sees intermittent updates, its core dependency, `node-sass`, is officially deprecated and no longer actively maintained. This means `node-sass-middleware` is primarily suited for maintaining existing projects rather than new development, where modern Dart Sass solutions are generally preferred. It integrates seamlessly into existing Connect or Express applications, offering a convenient bridge between Sass source files and served CSS.
