| Title: Node Version Manager
 | |

 | |
| 
 | |
| # Node Version Manager
 | |
| 
 | |
| Nvm is a version manager for Node.js. You can use it to install and switch to correct Node.js version.
 | |
| 
 | |
| ## Installation 
 | |
| 
 | |
| To install nvm you can run following:
 | |
| 
 | |
| ```sh
 | |
| curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.2/install.sh | bash
 | |
| ```
 | |
| for other installation options and troubleshooting instructions please follow [nvm installation docs](https://github.com/nvm-sh/nvm#install--update-script).
 | |
| 
 | |
| ## Usage
 | |
| 
 | |
| To use nvm run following command:
 | |
| 
 | |
| ```sh
 | |
| nvm use
 | |
| ```
 | |
| 
 | |
| which automatically use Node.js version specified in .nvmrc file. If given Node.js version is not installed you need to run:
 | |
| 
 | |
| ```sh
 | |
| nvm install
 | |
| ```
 | |
| 
 | |
| with version provided in .nvmrc file. Additionally if you want to install a new version of Node.js and migrate npm packages from a previous version run:
 | |
| 
 | |
| ```sh
 | |
| nvm install node --reinstall-packages-from=node
 | |
| ```
 | |
| 
 | |
| where 'node' is an alias for the latest version. For more details please refer to: [nvm usage](https://github.com/nvm-sh/nvm#usage).
 | |
| 
 | |
| ## Automatically call nvm use
 | |
| 
 | |
| To automatically call nvm use put the following at the end of `$HOME/.bashrc`:
 | |
| 
 | |
| ```sh
 | |
| cdnvm() {
 | |
|     command cd "$@" || return $?
 | |
|     nvm_path=$(nvm_find_up .nvmrc | tr -d '\n')
 | |
| 
 | |
|     # If there are no .nvmrc file, use the default nvm version
 | |
|     if [[ ! $nvm_path = *[^[:space:]]* ]]; then
 | |
| 
 | |
|         declare default_version;
 | |
|         default_version=$(nvm version default);
 | |
| 
 | |
|         # If there is no default version, set it to `node`
 | |
|         # This will use the latest version on your machine
 | |
|         if [[ $default_version == "N/A" ]]; then
 | |
|             nvm alias default node;
 | |
|             default_version=$(nvm version default);
 | |
|         fi
 | |
| 
 | |
|         # If the current version is not the default version, set it to use the default version
 | |
|         if [[ $(nvm current) != "$default_version" ]]; then
 | |
|             nvm use default;
 | |
|         fi
 | |
| 
 | |
|     elif [[ -s $nvm_path/.nvmrc && -r $nvm_path/.nvmrc ]]; then
 | |
|         declare nvm_version
 | |
|         nvm_version=$(<"$nvm_path"/.nvmrc)
 | |
| 
 | |
|         declare locally_resolved_nvm_version
 | |
|         # `nvm ls` will check all locally-available versions
 | |
|         # If there are multiple matching versions, take the latest one
 | |
|         # Remove the `->` and `*` characters and spaces
 | |
|         # `locally_resolved_nvm_version` will be `N/A` if no local versions are found
 | |
|         locally_resolved_nvm_version=$(nvm ls --no-colors "$nvm_version" | tail -1 | tr -d '\->*' | tr -d '[:space:]')
 | |
| 
 | |
|         # If it is not already installed, install it
 | |
|         # `nvm install` will implicitly use the newly-installed version
 | |
|         if [[ "$locally_resolved_nvm_version" == "N/A" ]]; then
 | |
|             nvm install "$nvm_version";
 | |
|         elif [[ $(nvm current) != "$locally_resolved_nvm_version" ]]; then
 | |
|             nvm use "$nvm_version";
 | |
|         fi
 | |
|     fi
 | |
| }
 | |
| alias cd='cdnvm'
 | |
| cd "$PWD"
 | |
| ```
 | |
| 
 | |
| or if you're using zsh put this into your `$HOME/.zshrc`:
 | |
| 
 | |
| ```sh
 | |
| # place this after nvm initialization!
 | |
| autoload -U add-zsh-hook
 | |
| load-nvmrc() {
 | |
|   local nvmrc_path="$(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" != "$(nvm version)" ]; then
 | |
|       nvm use
 | |
|     fi
 | |
|   elif [ -n "$(PWD=$OLDPWD nvm_find_nvmrc)" ] && [ "$(nvm version)" != "$(nvm version default)" ]; then
 | |
|     echo "Reverting to nvm default version"
 | |
|     nvm use default
 | |
|   fi
 | |
| }
 | |
| add-zsh-hook chpwd load-nvmrc
 | |
| load-nvmrc
 | |
| ```
