How to get bower/npm working

Can you provide more details on how to get bower/npm working with AppHarbor? It looks like I was able to get the packages to download to AppHarbor, but then the files all result in 404. As per another post on the support site, I added a postbuild event that I thought would get it working, but it doesn't. I read that the AppHarbor input and output folders are different, so I'm guessing that my node_modules folder needs to be copied from the input directory to the output directory? But the below doesn't work.

The build log seems to indicate that the copy command runs before the NPM packages are installed.

My csproj contains:
    <PostBuildEvent>if not exist "$(WebProjectOutputDir)\node_modules" md "$(WebProjectOutputDir)\node_modules"
start /MIN xcopy /s /y /R "$(MSBuildProjectDirectory)\node_modules\*.*" "$(WebProjectOutputDir)\node_modules"</PostBuildEvent>
  <Target Name="AfterBuild">
    <Exec Command="npm install" />
    <Message Text="Npm install finished" />

I changed the PostBuildEvent to include "npm install", but then it seems like couldn't find the packages.json file because it wasn't copied to the output directory.

Please see build fb1b6ab3 on my HoppeUAT site.

    Take a look at my comment in this discussion -- the customer was able to get bower up and running with the steps outlined there. Seems like that would also apply to the issue you're facing?

    Yes this is the thread I was referring to. Do you have any more info on
    this? I wasn't able to get it working.

    That depends -- what wasn't working and/or what errors did you encounter? :-)

    One possible cause: The post build script should be placed after the web application targets are imported in your project file. The macros for the website output directory isn't populated before those targets have been imported, so usually it's best to put this operation in the bottom of the project file.
