scalajs-react SSR demo

A Server-side rendering (SSR) demo for scalajs-react, based on https://blog.shipreq.com/post/scala_react_and_ssr_part_1

Dependencies

• scala-cli 1.0.1
• GraalVM 17 (sdkman can pick it automatically)
• Node (picked automatically by nvm)

Run

• Package sjs code: scala-cli --power package WebPageJs.scala -o js/webpage.js -f
• Run server code: scala-cli WebServerJvm.scala

Update react dependencies

Let's suppose we want to pick react 16, we'll download the dependencies through npm like this:

npm install react@^16.5.2
npm install react-dom@^16.5.2

Then, grab the minified js code:

cp node_modules/react/umd/react.production.min.js js
cp node_modules/react-dom/umd/react-dom-server.browser.production.min.js js

NOTE: The umd variant is the one that works.
