 You can use [`nvshim`](https://github.com/iamogbz/nvshim) to shim the `node`, `npm`, and `npx` bins to automatically use the `nvm` config in the current directory. `nvshim` is **not** supported by the `nvm` maintainers. Please [report issues to the `nvshim` team](https://github.com/iamogbz/nvshim/issues/new).

-This looks in the same directory as the `.envrc` file for an `.nvmrc`, loads the node version from it, then uses that version (installing it, if necessary).

 If you prefer a lighter-weight solution, the recipes below have been contributed by `nvm` users. They are **not** supported by the `nvm` maintainers. We are, however, accepting pull requests for more examples.
