Getting source maps working with evaluated code

Question

I have a build script that runs all my code through uglifyjs, does a bunch of fancy caching stuff, and ultimately runs eval( code ) on some JavaScript files.

Answer 1

I had a similar problem and the solution seem to be using an inlined SourceMaps (DataURL of a SourceMap).

Here is an example:

eval("blah blah\n//@ sourceMappingURL=data:application/json;base64,...");

Seems like you can't reference external resources from an eval.

I think you also need to use sourcesContent to insert the source code into the SourceMap.
