Aaaand I’m back after the lunch break. This time with @nikgraf! He’s talking about the new Reason React.pic.twitter.com/xOyYNiyWXJ

Reason has a feature called PPX which you can use to extend the syntax. You can use that to generate an actual module which can resolve the query to actual types. No type definitions but 100% type safety pic.twitter.com/ftqFnZPMkw

So that’s how a Hello World React component looks like in Reason React using the React PPX.pic.twitter.com/HJJo79R4eH

So Reason (and Ocaml) can infer the type of a React Component prop by looking at how the prop is used. In this example, the type for the prop “name”, “characteristics”, and “population” are automatically determined.pic.twitter.com/xTHaxhvk4W

Hooks in Reason React The compiler can infer the type for a useState hook again by looking at how you use the state.pic.twitter.com/J94rCodNqX

So we’re staying at Reason. @bryphe is talking about totally native React with Revery. Revery is a high-performance, React-inspired, native application stack built on top of the Reason programming language.pic.twitter.com/9kzDBA8kTp

So with Reason, Revery can use both native UI frameworks (like Cocoa on a Mac) and compile into native binaries while staying at a language that is highly productive. Great fit!pic.twitter.com/lYJEENwVcs

All of this can compile to JavaScript as well and just works in a browser.pic.twitter.com/VzchJvKSjV

Compared to Electron, a Revery app (compiled to native code) is a lot faster. pic.twitter.com/tcVPQth3By

I just realizes that the slides appear to be a React Native app running inside the iPad simulator pic.twitter.com/f7WATsZXn3

Wowzie it’s even using React Native Magic Move.pic.twitter.com/QA8CZt38nN
