Answer 1

There's npm package that's overwriting default EB behaviour for npm install command by truncating following files:

• /opt/elasticbeanstalk/hooks/appdeploy/pre/50npm.sh
• /opt/elasticbeanstalk/hooks/configdeploy/pre/50npm.sh

https://www.npmjs.com/package/eb-disable-npm

Might be better than just copying script from SO, since this package is maintained and probably will be updated when EB behaviour will change.
