What is it?
The scalajs-reaction website is a WIP.
API docs and the demo are not hooked up yet :-) You can generate docs and run the demo by cloning the repo and running them directly yourself.
A scala.js facade
scalajs-reaction is a scala.js facade over reactjs that provides a functional API in the spirit of ReasonReact. It focuses on integration with existing javascript-based react applications so you can plug in scalajs-react components to any part of the component hierarchy.
A scalajs-reaction component is just a javascript function and you can easily create that using standard scala.js code. Nothing new is invented in this facade.
The library is designed to create components that can be used and consumed by other react components in javascript and scala seamlessly.
The library is also designed to be a thin layer over react and not provide abstractions that you may or may not want. Abstractions have costs and when it comes to running in the browser, I found that it was better to have a react library with lower overhead and build the abstractions at much higher levels in the application. Accordingly, the facades favor simple scala.js interfaces into the javascript side of the react world. Abstract your own concepts on top with assurance that this library adds very little overhead.
This library does provide a few optional macros for working with scala.js traits. I spend most of my time writing facades for people who want to use scalajs-reaction so you'll see there is a wide variety of facades available including support for react-native. You can also use it on electron easily.
Since the project is kept very simple, the scalajs-reaction ecosystem takes very little effort to maintain.
ReasonReact
The interface is built on the model provided by ReasonReact. You can apply the same concepts in that library to this API.
The ReasonReact approach is to provide robust interfaces to hooks. scalajs-reaction follows this model is 100% hooks focused. It does not provide any facade support for class based components. Anyway, you should be using hooks.
API Documentation
The API focuses on integration with existing javascript libraries. For example, it is easy to interface with redux and it allows you to connect your component to an existing redux store. More importantly, it allows you to interface with the great set of reactjs widget libraries.
The API link does not include some of the individual projects that provide facades for additional functionality but it provides a significant amount of the core facades. In other words, there is more here so check the source!
