A shell script which can help the nvm to detect .nvmrc and .node_version file

load-nvmrc.sh

#!/bin/bash

load-nvmrc() {
  local nvmrc_path
  nvmrc_path="$(nvm_find_nvmrc)"

  if [ ! -e "${nvmrc_path}" ]; then
    local LOCAL_NODE_VERSION_DOTFILE_PATH
    LOCAL_NODE_VERSION_DOTFILE_PATH="${PWD}/.node-version"
    if [ -e "${LOCAL_NODE_VERSION_DOTFILE_PATH}" ]; then
      nvmrc_path="${LOCAL_NODE_VERSION_DOTFILE_PATH}"
    fi
  fi

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

    if [ "$nvmrc_node_version" = "N/A" ]; then
      nvm install
    elif [ "$nvmrc_node_version" != "$(nvm version)" ]; then
      nvm use "$nvmrc_node_version"
    fi
  elif [ -n "$(PWD=$OLDPWD nvm_find_nvmrc)" ] && [ "$(nvm version)" != "$(nvm version default)" ]; then
    echo "Reverting to nvm default version"
    nvm use default
