Fix failing node deployments on AWS Elastic Beanstalk

Elastic beanstalk runs npm install with a system user that has no homedir. During the npm install step, it's expecting a $HOME env variable for the npm cache (which doesn't exist). add this file to your project's .ebextensions directory to have it use root's homedir as a temporary path.

This workaround was provided by AWS support, but it doesn't appear to be documented anywhere. Determining root cause on this was a massive pain in the ass. Sharing this so others don't need to feel the pain.

• When this app is started with node index, a SIGINT (Ctrl+c) is caught by the app and it continues running.
• When this app is started with npm start, a SIGINT causes npm to exit, detaching the still running node process from the foreground.
