webpack-core

The shared core of webpack and enhanced-require, encapsulating loader mechanics and SourceMap handling. Version 0.6.9 is the latest (no longer maintained; last release 2014). It is not intended as a standalone module but provides infrastructure for custom loaders and plugins. Webpack 1.x used this; later versions replaced it with webpack-sources and internal refactoring. Key differentiator: it was the foundational runtime for webpack's loader pipeline before being absorbed into webpack proper. Requires Node >=0.6.
