As we are using node here, the repo should have a .nvmrc file

Please discover nvm: https://github.com/creationix/nvm, this allow to swith node version and run the correct ones.
Using a .nvmrc file allows to make sure that the user / developer will use the same version you tested your software on.

As i have a windows machine I downloaded nvm-windows: https://github.com/coreybutler/nvm-windows to switch between versions of node.js. Which works fine, but as far as I could figure, out the developer of nvm-windows doesnt want to integrate .nvmrc into his version: coreybutler/nvm-windows#108 coreybutler/nvm-windows#128
