# Projects which rely on npm modules which are normally installed using "npm install -g"
# can make those dependencies available on OpenShift by including this file in their project source.

# Add this content to your project as ".openshift/action_hooks/pre_build_nodejs"
# Then, save your npm dependencies locally (without the '-g' flag):
# > npm install module_name --save

# Finally, add and commit your changes:
# > git add package.json .openshift/action_hooks/pre_build_nodejs node_modules
# > git commit -m 'relying on the pre_build_nodejs action hook to include npm mods in path'
# > git push

# This code works by automatically creating symlinks for npm executables 
# that are included in your project's $OPENSHIFT_REPO_DIR/node_modules/.bin folder,
# making them available in the system $PATH under "~/.node_modules/.bin"
