Add dependencies to tar?

[drumnation]

I'm using node-fetch in my library and that is not installed in my react-native project. When it uses the api call in my library it looks for the node-fetch library to be installed inside node_modules/myLibrary/node_modules/node-fetch and it isn't there. I've been trying to come up with a way to do this, but the best I've been able to do is to get node_modules/node-fetch into the build folder of the app when it needs to be in the root level of the package to satisfy the app.

Is there a way where dependencies could be added to the tarball? Installing them in the folder of my react-native app is one way, but as soon as a change is made to the library the tar copies over what was in the directory requiring another time consuming install. If it could just copy the installed node_modules package into a node modules folder in the tarball it would work for me.

Thoughts? Great library.

Thanks.
