NeDB error with Rollup & Electron

[nnooney]

I'm building an app with NeDB and Electron and using Rollup to bundle the JS modules I include. When I compile the JS and start the application with Electron, I get the following error:

TypeError: Cannot read property 'prototype' of undefined

Here is a gist that can reproduce this issue:

Investigating the stack leads back to an issue with line 81 in lib/datastore.js. What I think is happening is that Rollup cannot resolve a require statement that handles object notation. To fix this, I've moved the require statement to the top of the file. The fix can be seen in the following pull request:
