Actually all you need is this: ``` componentDidMount() { window.addEventListener('scroll', this.onScroll, false) this.initialLoad() } componentWillUnmount() { window.removeEventListener('scroll', this.onScroll, false) } onScroll() { if (window.innerHeight + window.scrollY >= document.body.offsetHeight - 300)...

Need this! MongoLabs updated to MongoDB to v3. Please merge.
