Sourcemaps for combined js file

Hi,

We use Raygun.io for crash-reporting in production, and we found that without sourcemaps, the error details are not very helpful. I know connect-assets support source maps for seperate js files, but we are using a single combined js file in production, whose source look like this:

// This is application.js
//
//= require semantic-ui
//= require highcharts/highcharts
//= require highcharts/modules/drilldown
//= require polyglot/build/polyglot
...

Is there anyway to generate a sourcemap file for the combined js? I’m thinking something like application.js.map?

Thanks a lot!

We really should have better source map support for production environments. The focus of the source map support originally was for dev and staging kinds of use cases. I’ll look into making it easy to use source maps for production (outputting for upload to external services and such).

Thanks for the input!

Finally had the time to take a look at this and I just published 5.3.0 that now has a --sourceMaps option for the CLI! This will write the source map for each file to the builtAssets directory with the .map extension appended to the original filename.

@codynguyen and @siboulet: Let me know how it works for you guys and if there’s something I’ve missed. Sorry for the month delay on this one.
