Automatically use the correct node version with zsh and nvm
I like to use nvm to manage the node version on my machine and therefore it is only logical to have also a .nvmrc
file in projects, which I use to set the appropriate node version.
In this project it is about the current LTS version of node:
lts/*
Now when I switch projects I could just run nvm use
to load the version, but honestly I tend to forget to do that. Fortunately, this can be quickly corrected with a tweak in my ~/.zshrc
(I use Zsh and Oh My Zsh). After the initialization of nvm you just have to insert the following code:
# 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-nvmrc
You can find that in the official doc to nvm, but who ever reads instructions đ
