Automatically use the correct Node version when changing directories with NVM

TLDR: Copy the script below to your .bash_profile (Mac) or .bashrc (Linux) to use the correct node version when starting a terminal session or changing directories.

There are plenty of tools that can do this for you, but bash is all you need. It will define a function which will check to see if a .nvmrc file exist and call nvm use if it does. I immediately invoke the function because the user might be opening a new terminal session in a directory that contains an .nvmrc file. Otherwise, I hijack cd and call the useNvmVersion function after a user has changed directories.

function useNvmVersion {
    if [ -f .nvmrc ]; then
        nvm use


function cdEnhanced {
    cd $1

alias cd=cdEnhanced
