#### Extra commands to trigger lazy loading
By default lazy loading nvm is triggered by running the `nvm`, `node`, `npm` commands or any installed npm global binaries.
If you want to trigger the lazy loading via extra arbitrary commands you can define `NVM_LAZY_LOAD_EXTRA_COMMANDS` and set it to an array of commands as strings.
```shell
export NVM_LAZY_LOAD_EXTRA_COMMANDS=('vim', 'ls')
vim --version
#node is now loaded
```
### Don't autoload node ### Don't autoload node
By default when `nvm` is loaded it'll automatically run `nvm use default` and load your default `node` version along with `npm` and any global modules. You can disable this behaviour by exporting the `NVM_NO_USE` environment variable and setting it to `true`. It must be set before `zsh-nvm` is loaded.
