Locking Dependencies with npm shrinkwrap
The Node.js platform runs npm install each time you deploy. When new versions of your dependencies are available, they
will be installed
when you deploy your application, potentially causing the deployment to take a long
time.
You can avoid upgrading dependencies by creating an npm-shrinkwrap.json file that locks down your application's dependencies to the
current version.
$npm install$npm shrinkwrapwrote npm-shrinkwrap.json
Include this file in your source bundle to ensure that dependencies are only installed once.
