The SharePoint Framework isn't just for online any more. With the release of Feature Pack 2 for SharePoint 2016, you can now develop modern enterprise web parts on premises using Typescript and an open source build chain. In this session we'll briefly cover the build and deployment process, creating web parts with ReactJS, and making them reusable by providing end user configurable properties. We'll also talk about differences between SPFx online vs. on premises and developing components that work on both.
