Changing node versions automatically per directory
Working in multiple Node projects sometimes means using different versions of Node. nvm is one popular solution for Linux, macOS and Windows WSL that handles multiple Node installations. One of its most unknown tricks is the deeper shell integration. Check the video:
If you are using macOS Catalina, you are probably using ZSH as default shell. To make the magic happen, paste the following in ~/.zshrc file.
~/.zshrc
# place this after nvm initialization!
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-nvmrcAfter restarting your terminal, nvm will automatically change the version of Node based in the current folder.
