NVM is a version manager for node that makes using specific versions of Node a breeze. I prefer to use it on my development machine instead of system wide node as it gives much more control with almost no added complexity.
Once you install it , it adds the following snippet to your .bashrc :
|
1 2 |
export NVM_DIR="/Users/zaro/.nvm" [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm |
and everything just works 🙂
Except that on my laptop this adds 1-2 seconds of start up time to each new shell I open. It’s a bit of annoyance and I don’t need it in every terminal session I start, so I though maybe there will be a way to load it on demand.
After fiddling a bit with it I replaced the NVM snippet with the following:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
nvm() { unset -f nvm export NVM_DIR=~/.nvm [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm nvm "$@" } node() { unset -f node export NVM_DIR=~/.nvm [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm node "$@" } npm() { unset -f npm export NVM_DIR=~/.nvm [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm npm "$@" } |
Now nvm, node and npm are loaded on their first invocation, posing no start up time penalty for the shells that aren’t going to use them at all.
Edit: Thanks to jonknapp’s suggestion, now the snippet is more copy paste friendly.
Edit: fl0w_io made a standalone script out of it to include in .bashrc
Edit: sscotth made a version that will register all your globally installed modules
