Run n auto, but only if you need to. Read more about it here!
Running this script will try to read a Node.js version constraint from the closest package.json file in the tree, match the current version against it, and run n auto if they do not match.
It needs to receive a path to a file containing all available Node.js versions as an argument; this file can easily be generated with n ls-remote --all.
This is meant to be ran upon cd to switch automatically while keeping it fast.
$ npm iIn .zshrc (for example):
autoload -U add-zsh-hook
n ls-remote --all > path/to/.node-versions
switch-node-version() {
node path/to/runn path/to/.node-versions
}
add-zsh-hook chpwd switch-node-version
switch-node-version
