NodeJS: add options to npmrc

Question

I am currently running my script as

node --no-deprecation main.js

I was wondering if there is a way to add this option to ~/.npmrc or otherwise (environment variable), such that I do not need to add the option to the command line. I would like to just run my script as node main.js and to be shown no deprecation warnings.

To make this question more general, is there a general way in NodeJS of setting flag values in a config file rather than adding it to the command (say I am interested in running with --trace-warnings as well.

I am looking for something cleaner than say alias node="node --no-deprecation".

I already tried adding this line inside ~/.npmrc

no-deprecationss=true

If you're looking for a global configuration, setting the --no-deprecation flag in the NODE_OPTIONS environment variable in your .bashrc or other shell config file is what you're looking for, as long as you're using node v8 or above.
