Is there a way to update specific dependency according to package.json changes?

Question

I am writing deployment scripts for my application on AWS. I created an AMI and it will run following scripts after boot.

cd $APP_DIR
git pull
npm install
npm start

It works alright until I updated some of my dependencies (e.g. React v0.12 -> v0.14). It looks like npm install will not update the module that already installed.

Currently I have two options:

Add rm -rf node_modules before npm install, but it is really expensive in booting phase.
Every time existing dependency updated, create a new AMI. Obviously annoying because then I have extra dumb work on update launch-profile and auto-scaling settings.

Is there an easier way to update modules only when their versions changed in package.json?

Try running `npm update`. Also this has nothing to do with AWS. — Mark B, Dec 03 '15 at 21:44
@MarkB Blame me. I didn't look deep into `npm update`. Thanks! — Yu J., Jan 12 '16 at 22:51

You can use npm update to update all modules listed in package.json depending on caret (^), tilde (~) or asterisk (*) before their name.
