Set node version differently for specific project(folder) via NVM

I know I can change the node version by nvm use CLI command. However, I want to set specific node version differently for a certain project(folder). It's changed via nvm use command but it's reverted to default version whenever I restart the terminal or webstorm IDE.

How can I set nvm remember this different version for a certain project(folder)?

using .zshrc, without always running nvm use

Use case:

  1. If you want to use a different node version for a specific directory.
  2. changing into this directory will switch to your desired node version
  3. cd out of this directory will switch back to the default node version

Solution here

  1. create a .nvmrc file in the desired directory and add your required <node version>

Ex: 18 or 18.1 or 18.3.1 and ensure the specified version is installed on your machine. If 18 is mentioned, any installed version with a major as 18 will be picked.

  1. Add below lines to your .zshrc
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"

nvm_auto_use() {
  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 nvm_auto_use
nvm_auto_use

PS: All the child directories inside the directory with .nvmrc also inherit the node version

You can use a .nvmrc file in the root of the project with the version you want to use. For example v12.4.0 or v10.16.0. You have to make sure that this version is installed or it will use the default node version in your machine.

One solution that I've found that works for me is creating an alias in your terminal of choice, in my case in .zshrc so that I can cd into the folder project and change the node version at the same time so I don't forget every time I get to that specific folder to change the node version with nvm. The alias looks like that:

alias foo='cd ~/route/to/project/folder && nvm use <node_version>'

One more method could be to use direnv. Create one file .envrc at the root of the folder where you want to use a different node version.

For example:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
nvm use <node_version>

Then run to allow using of this .envrc file.

direnv allow
  • First two lines just load the nvm, for some reason does not pick it up from .zshrc.
  • Second line would change the nvm version to the one you want to use.

For example, you want your default node version for this project to be v12.
Open your command line in the project root folder, then run nvm use 12, then run node -v > .nvmrc. It won't solve your issue completely because you'll anyway have to run nvm use just without the version.
