Node-Sass is a library that provides a JavaScript implementation of the Sass (Syntactically Awesome Style Sheets) preprocessor. Sass is a CSS preprocessor that extends the capabilities of CSS with features like variables, nesting, mixins, and inheritance, making stylesheets more maintainable and organized. Node-Sass allows developers to compile Sass files into standard CSS that can be understood by web browsers.

It is widely used in front-end development workflows. By using Node-Sass, developers can write more efficient and powerful CSS. The library is typically installed as a development dependency in a Node.js project using npm or yarn. Once installed, it can be integrated into build tools like Webpack, Gulp, or Grunt, automating the compilation process whenever Sass files are modified.

Node-Sass offers a command-line interface (CLI) for direct compilation of Sass files, as well as an API for programmatic use within JavaScript applications. This flexibility makes it a popular choice for projects of all sizes. While Node-Sass was a dominant force for a long time, a newer, faster implementation called Dart Sass has become the recommended option by the Sass community. However, Node-Sass remains in use in many existing projects.
