Example

cdnvm() {
    command cd "$@" || return $?
    nvm_path="$(nvm_find_up .nvmrc | command tr -d '
')"
    if [[ ! $nvm_path = *[^[:space:]]* ]]; then
        default_version="$(nvm version default)"
        if [ $default_version = 'N/A' ]; then
            nvm alias default node
            default_version=$(nvm version default)
        fi
        if [ "$(nvm current)" != "${default_version}" ]; then
            nvm use default
        fi
    elif [[ -s "${nvm_path}/.nvmrc" && -r "${nvm_path}/.nvmrc" ]]; then
        nvm_version=$(<"${nvm_path}"/.nvmrc)
        locally_resolved_nvm_version=$(nvm ls --no-colors "${nvm_version}" | command tail -1 | command tr -d '\->*' | command tr -d '[:space:]')
        if [ "${locally_resolved_nvm_version}" = 'N/A' ]; then
            nvm install "${nvm_version}";
        elif [ "$(nvm current)" != "${locally_resolved_nvm_version}" ]; then
            nvm use "${nvm_version}";
        fi
    fi

alias cd='cdnvm'
cdnvm "$PWD" || exit
