Node.js- Splitting up File Path with string.split()... Top Level File Gets Excluded

I have these routines that split up the file path. The issue that I am having is with /home/one/github/load-balancer-service/app/js/app.coffee. It seems to exclude the app.coffee and just leaves /js/ for srcFile

Not sure why. Any ideas? For files in sub directories underneath js/foo/file.coffee it's not a issue.

  srcPath = "app";
  console.log(streamObject.history[0]);
  var projectDir = streamObject.history[0].split(srcPath)[0];
  console.log(projectDir);
  var srcFile = streamObject.history[0].split(srcPath)[1];
  console.log(srcFile);

output:

/home/one/github/load-balancer-service/app/js/app.coffee
/home/one/github/load-balancer-service/
/js/
