feature

What is the current behavior?

Set devtool;. NODE_ENV === PRODUCTION ? 'nosources-source-map' : 'eval-source-map';

Sourcemap type is built.

If the current behavior is a bug, please provide the steps to reproduce.

What is the expected behavior?

If this is a feature request, what is motivation or use case for changing the behavior?

What we'd like is to be able to create multiple sourcemaps for production as a single run.

Set devtool: NODE_ENV === PRODUCTION ? ['nosources-source-map', 'source-map'] : 'eval-source-map';

The first sourcemap will be used client side and included in the the js e.g. //# sourceMappingURL=index.js.map

The second sourcemap would be used for our monitoring system, and would have a filename for example index.js.map2 or anything sensible.

All this would be performed in a single build run.

Perhaps this is already possible and we just haven't discovered how.

Please mention other relevant information such as the browser version, Node.js version, webpack version, and Operating System.
