We're trying to setup our app to send the generated source maps to NewRelic in order to debug any JS errors that occur in our production environment, and they have a requirement that the source maps need to include the source content in the map file via the sourcesContent component. I know this is an optional component of the source map, but there doesn't seem to be a way to configure sprockets to include it.

Expected behavior

We should be able to configure sprockets to opt-in to including the sourcesContent in the source map.

Actual behavior

There currently does not seem to be a way to opt-in to including the sourcesContent component of the source maps.

System configuration

• Sprockets version: 4.0.0.beta8
• Ruby version: 2.3.4
