Awesome React

Making your app fast with high-performance components

We can all appreciate that React apps are easy and awesome. They make great demos that are crushingly good at DOM-manipulations. But as they grow (and they always do), things start to get unwieldy. Big apps — especially ones with long life-spans, huge data sets, or numerous contributors — can suffer serious perf and maintenance inefficiencies.

The Facebook Ads Interfaces team shares what they’ve learned after spending the last year building one of the world’s largest React applications. By being intentional about your app's component hierarchy, separation, and data-passing, you can achieve excellent performance, sustainable even at a massive scale.
