How to use distinctly compiled npm packages across a host machine & VM with a shared project folder

Use bcrypt and mongoose in each, with their own, OS-specific bindings

1. Go to your ~/ home directory on the machine you want to install OS-specific module for, then run $ npm i compiled-package

2. Move your package into ~/.node_modules folder (this is a special folder node knows to look in when requireing modules)

• So probably: $ mv ~/node_modules/compiled-package ~/.node_modules/compiled-package
  • Shorthand: $ mv ~/{,.}node_modules/compiled-package
• (consider rm -rfing the first node_modules folder to clean up after yourself)
