Stay tuned as Emily demonstrates the ease of integrating this tweak into your workflow. With her tips, managing Node environments becomes as simple as hopping into a directory, perfect for the forgetful among us keen on keeping our Shell game strong.
Automatically Run nvm use Shell Function
Recently I've found myself forgetting to run nvm use , so I decided to add it to my usual cl function.
Here's the basic version:
# A function used as a more advanced version of `cd`
# - Changes into the specified directory
# - If an .nvmrc file exists, active it using `nvm use`
function cl () {
cd "$@"
if test -f ".nvmrc"; then
echo "🔎🔎🔎 .nvmrc found - activating Node environment\n"
nvm use
fi
}And my full cl command:
# A function used as a more advanced version of `cd`
# - Changes into the specified directory
# - Clears the screen
# - If an .nvmrc file exists, active it using `nvm use`
# - Lists the current directory
function cl () {
cd "$@" && clear
if test -f ".nvmrc"; then
echo "🔎🔎🔎 .nvmrc found - activating Node environment\n"
nvm use
fi
ls -laAhF
