# Add our package.json and install *before* adding our application files
# So, we add in only our package.json file and run npm install --production.
# Once that's done, then we can add our files using ADD. Since we ordered
# the steps this way and chose to have Docker ignore our local node_modules
# directory, the costly npm install --production step will only be run when
# package.json has changed. This will save build time and hopefully result
# in a speedier deploy process.
