I’ve mentioned in several previous threads that I’ve been using Cesium in a React application, and building it with Webpack. I’ve wanted to write a blog post for a while that discusses some of the techniques involved, and I was finally able to do so. I just published a 2-part post on “Declaratively Rendering Earth in 3D: Using Cesium with React and Webpack”. Part 1 covers basic Cesium+Webpack setup and build optimization with DllPlugin. Part 2 shows declarative React components that wrap imperative APIs:

Hope this helps!
