`importNpmLock.buildNodeModules` returns a derivation with a pre-built `node_modules` directory, as imported by `importNpmLock`.
This is to be used together with `importNpmLock.hooks.linkNodeModulesHook` to facilitate `nix-shell`/`nix develop` based development workflows:
```nix
pkgs.mkShell {
packages = [
importNpmLock.hooks.linkNodeModulesHook
nodejs
];
npmDeps = importNpmLock.buildNodeModules {
npmRoot = ./.;
inherit nodejs;
};
}
```
will create a development shell where a `node_modules` directory is created & packages symlinked to the Nix store when activated.
