Sort of useless, but if you’re annoyed that Webpack’s output files have re-indented your exquisitely space-indented source files with a tab (no-mixed-spaces-and-tabs!), just set output.sourcePrefix to spaces in your webpack.config.js file.
The main reason I did this was to be able to review the output files in a text editor without triggering thousands of ESLint indentation errors.
