I\'m building two projects with webpack; one is a library for the other.
Is it possible to consume the sourcemaps from my library project when building my wrapper projec
You should be able to use any of the eval source map options that Webpack provides.
Really that just amounts to setting the right devtool option in your webpack.config.js for the my-lib project.
devtool: 'eval',
eval and eval-source-maps should both work.
See the Webpack source map documentation for the various options.
