nvm Shell Integration

Add automatic nvm use on directory changes so the correct Node version activates per project.

Workflow

1. Add auto-switching for bash (append to ~/.bashrc):

   bashCopy

   cdnvm() {
     command cd "$@" || return $?
     nvm_path="$(nvm_find_up .nvmrc | command tr -d '\n')"
     if [ -n "$nvm_path" ]; then
       local nvm_node_version=$(nvm version "$(cat "$nvm_path/.nvmrc")")
       if [ "$nvm_node_version" = "N/A" ]; then
         nvm install
       elif [ "$nvm_node_version" != "$(nvm version)" ]; then
         nvm use
       fi
     fi
   }
   alias cd='cdnvm'
   

2. Deactivate nvm and restore PATH when needed:

   bashCopy

   nvm deactivate   # Removes nvm from PATH, restores system node
   nvm use system   # Switch to system-installed Node
   

3. Verify auto-switching works:

   bashCopy

   echo "20" > /tmp/test-project/.nvmrc
   cd /tmp/test-project   # Should auto-switch to Node 20
   node -v                # Should show v20.x.x
   

Note: Base shell loading belongs to nvm-setup. This skill adds deeper integration on top.
