{"id":20760,"library":"webpack-externalize-lodash","title":"webpack-externalize-lodash","description":"A utility function for webpack that externalizes lodash from your bundle, handling all common import patterns (lodash, lodash-es, lodash-specific submodules like lodash/get, lodash-es/get, lodash.get). Version 1.0.1, stable. Unlike simple externals config like { lodash: '_' }, this package uses webpack's externals function to cover edge cases where lodash is imported in multiple ways by different dependencies, preventing duplicate inclusion.
