Via rollup/rollup-plugin-babel#64 – including helpers (e.g.
babelHelpers
) in sourcemaps causes all sorts of chaos. It makes more sense to exclude these virtual modules from the sourcemap.In magic-string, you can exclude a source from the
sources
array by not giving it a filename, so this just filters out sources that have the\0
character (convention to indicate plugin helpers/virtual modules).
