I suspect this should probably be packaged from github, as the javascript in the NPM tar ball is not the original upstream code - it has been generated from the source code in the git repo using the gulpfile.

Unfortunately that's probably going to add a load of dependencies...

It looks like the only thing that the gulpfile does (as far as building goes) is to remove a dep on es6-transpiler.  Here's a new release with:

 - Latest upstream.                         
 - Github tarball instead of npmjs.     
 - Specify noarch.                          
 - Remove es6-transpiler in the prep section in lieu of gulp.

By removing es6-transpiler ourselves, we can (hopefully) avoid packaging gulp for now.  What do you think?

Spec URL: http://threebean.org/rpm/SPECS/nodejs-postcss.spec
SRPM URL: http://threebean.org/rpm/SRPMS/nodejs-postcss-2.2.0-1.fc20.src.rpm

Well the point is that the gulpfile runs es6-transpiler on the source to create the js that goes in the npm tar ball - the build:lib task.

Other than that, this has a dependency on js-base64 which doesn't seem to be packaged yet.

js-base64, huh?  which is.. not the same as base64-js.  https://bugzilla.redhat.com/show_bug.cgi?id=1115661

Tom, it's not clear to me which side of this you come down on.  Do I need to also package gulp, es6-transpiler, and their deps to move forward here?  (js-base64 is now taken care of).

Well you can probably get away without gulp, and just run transpiler directly in the spec but I don't see any way to avoid transpiler if we're genuinely going to package from source.

You could always ask on the fedora nodejs list and see if people have any suggestions?

Ralph,

It seems that in the newer versions the dependency on es6-transpiler is dropped. 

Could you please check if you can update to the latest version?

I've update to 5.0.3, this eliminates the dependency on es6-transpiler but adds a new dep on nodejs-babel-core which has many missing dependencies.

Doing an informal package review to help keep the ball rolling here... Other than the rpmlint errors caused by the commented Source0 line in the spec file, this package is looking good to me.

The new version depends on babel which is not packaged yet.

I'm no longer pursuing this one.  Thanks to everyone for the assistance here.
