In a web app, the enemy of performance isn't bad algorithms — it's bloat. Enter Isograph, the framework for building data-driven React apps. It leverages a compiler to provide great DevEx and performance, right out of the box. In this talk, find out how Isograph lets you: load component JavaScript and data only when needed, for example when the user is about to scroll to them; load components (such as a VideoViewer) only if an item of that type (a Video) is returned from the server, and defer loading parts of your component tree, without server support. And the cherry on top? We're doing it all in userland. 😎
