webpack-common-shake

Webpack plugin for tree-shaking CommonJS modules. Version 2.1.0 is the latest stable release, published in 2019. It removes unused assignments to exports properties, leaving dead code elimination to UglifyJS. Unlike ES module tree-shaking, this targets CommonJS exports. Works with Webpack 4+; for Webpack 3 use version 1.x. Provides options for warnings and bailout callbacks. Notable limitations: dynamic exports, dynamic require, and certain re-assignments cause bailouts.
