Description of change
This is a partial revert to the karma/webpack-stream package and subsequent node updates introduced by #4038
As part of these updates, there was a requirement to have to use Node 9 (or greater) due to karma's use of the spread operator in its workflow; the spread operator (ie
...args
) is only available in Node 9+.The internal build system that we use for the prebid.js releases is not currently up to this version of node and would need some additional time to get it updated. So we're temporarily reverting these updates in the meantime.
The other changes from the original PR (namely the
process.exit
commands in thegulpfile
) are left intact since they are needed to help ensure the circleCI complete successfully and are not impacted by the node version.
