Jennifer Kenderdine gave a presentation on the SharePoint Framework (SPFx) which allows building client-side web parts for SharePoint using modern web technologies. SPFx uses the same context and connection as the browser, allows controls to render in the DOM, and is framework agnostic. It supports both classic and modern pages in SharePoint. Developers need an Office 365 developer tenant and tools like Node.js, Yeoman and Gulp to build SPFx solutions. The development workflow involves creating a project, editing the web part with TypeScript, testing locally and deploying to a CDN.
