webpack-deep-scope-plugin

A webpack plugin that improves tree-shaking by performing deep scope analysis to eliminate unused imports related to unused exports. Version 1.6.2 requires webpack ^4.14.0 and Node.js 8+. It solves webpack issue #6264 by analyzing variable scopes and removing dead code more aggressively than standard tree-shaking. Uses TypeScript and includes a custom version of escope. Alternative to webpack's built-in sideEffects flag but only works with ES module syntax (import/export).
