In zsh, I have a different setup in my ~/.zshrc that not only lazyloads nvm and node, but also any globally-installed package

# Add every binary that requires nvm, npm or node to run to an array of node globals
NODE_GLOBALS=(`find ~/.nvm/versions/node -maxdepth 3 -type l -wholename '*/bin/*' | xargs -n1 basename | sort | uniq`)
NODE_GLOBALS+=("node")
NODE_GLOBALS+=("nvm")

# Lazy-loading nvm + npm on node globals call
load_nvm () {
  export NVM_DIR=~/.nvm
  [ -s "$(brew --prefix nvm)/nvm.sh" ] && . "$(brew --prefix nvm)/nvm.sh"
}

# Making node global trigger the lazy loading
for cmd in "${NODE_GLOBALS[@]}"; do
  eval "${cmd}(){ unset -f ${NODE_GLOBALS}; load_nvm; ${cmd} \$@ }"
done
