React Responsively, Render Responsibly

Yoav Niran at ReactNext 2018

The main premise of modern reactive applications is that they provide high-performance out of the box, making the user experience feel blazingly fast. Yet, there’s a limit to the magic that even React can pull off. There are times we need to help it, and often we might actually hurt the performance of our applications. In this talk I will do a live demo of investigating and resolving performance issues such as how immutable state' can actually adversely affect performance or how inefficient selectors can lead to components unnecessarily re-rendering. Using the Chrome Dev Tools and other profiling tools provided by React itself, we will discover how to find what's causing slowdowns. Then we'll go through the best practices needed to make our app blazing fast again.
