Node Dependencies and NPM

Updating

After installing the files, you may want to update the node dependencies. This is analogous to updating gem versions:

cd client
npm install -g npm-check-updates
rm npm-shrinkwrap.json
npm-check-updates -u
npm install
npm prune
npm shrinkwrap

Confirm that the hot replacement dev server and the Rails server both work. You may have to delete node_modules and npm-shrinkwrap.json and then run npm shrinkwrap.

Note: npm prune is required before running npm shrinkwrap to remove dependencies that are no longer needed after doing updates.

Adding New Dependencies

Typically, you can add your Node dependencies as you normally would. Occasionally, adding a new dependency may require removing and re-running npm shrinkwrap:

cd client
npm install --save module_name@version
# or
# npm install --save_dev module_name@version
rm npm-shrinkwrap.json
npm shrinkwrap
