If you use creationix/nvm
like I do, you will have probably ran into some painfully slow zsh startup times (10-ish seconds).
And this is not an uncommon symptom:
After digging through the interwebs for a bit, I could determine and conclude that the biggest culprit of all were these lines added to the end of .zshrc
during the installation process:
export NVM_DIR="${XDG_CONFIG_HOME/:-$HOME/.}nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
There were many other solutions: lazy-loading, adding a -no--use
flag to the running of nvm.sh
, but what I found worked for me was the following script I found:
if [ -s "$HOME/.nvm/nvm.sh" ] && [ ! "$(type -t __init_nvm)" = function ]; then
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/bash_completion" ] && . "$NVM_DIR/bash_completion"
declare -a __node_commands=('nvm' 'node' 'npm' 'yarn' 'gulp' 'grunt' 'webpack')
function __init_nvm() {
for i in "${__node_commands[@]}"; do unalias $i; done
. "$NVM_DIR"/nvm.sh
unset __node_commands
unset -f __init_nvm
}
for i in "${__node_commands[@]}"; do alias $i='__init_nvm && '$i; done
fi
