NVM Auto Use

Managing Node versions is a rite of passage, and around here at GoodFit we lean on NVM to keep things tidy.

If you haven't installed it yet, you can summon it with:

brew install nvm

Once that's squared away, drop the snippet below into your shell config. It keeps an eye out for a .nvmrc file whenever you hop between directories and seamlessly switches to the right Node version.. no more manual nvm use rituals 😌

NOTE: Ensure this snippet is placed after nvm has been initialised.

# NVM Auto Use
autoload -U add-zsh-hook
load-nvmrc() {
  local node_version="$(nvm version)"
  local nvmrc_path="$(nvm_find_nvmrc)"

  if [ -n "$nvmrc_path" ]; then
    local nvmrc_node_version=$(nvm version "$(cat "${nvmrc_path}")")

    if [ "$nvmrc_node_version" = "N/A" ]; then
      nvm install
    elif [ "$nvmrc_node_version" != "$node_version" ]; then
      nvm use
    fi
  elif [ "$node_version" != "$(nvm version default)" ]; then
    echo "Reverting to nvm default version"
    nvm use default
  fi
}
add-zsh-hook chpwd load-nvmrc
load-nvmrc

Once this is in place, just roam your project directories and let your shell magically keep your Node universe aligned. 🧙🏻‍♂️
