Using with CSS files that don't support CSS modules

If you have CSS files in your project that aren't CSS modules (for example, bootstrap), you can make them work by adding them to the passthroughPaths option:

"passthroughPaths": [ "bootstrap.css" ]

The property takes a wildcard, so you can get as specific as you like:

"passthroughPaths": [ "^client/lib/bootstrap/bootstrap\\.css" ]

See Package Options for more details.
