Facebook released a rewrite of a large portion of React last week. React 16 has been much anticipated, and the new Fiber rendering pipeline allows for a lot of performance improvements. While the React team has diligently deprecated methods and packages throughout the last version, warning us strongly in console statements to upgrade, the actual final migration is not trivial for larger codebases. We at Discord just launched our React 16 based app and wanted to share our experience and some tips we learned along the way.
