# install webpack-unused npm install -g webpack-unused # run webpack using your normal webpack config etc # with the --json switch to output the stats.json, and pipe to webpack-unused # unused files in the cwd will be listed webpack --json | webpack-unused # if your source code is in a directory, like src/ pass that as a flag: webpack --json | webpack-unused -s src
