Scala.js + Slinky Expo Template
This template sets up a simple React Native application written in Scala through Scala.js, Slinky, and Expo.
Installation
Install the Expo CLI:
$ npm install -g expo-cli
Use the template
$ expo init --template expo-template-scala
Building Apps
Once you've created your project, first compile your Scala code to JavaScript by running
$ sbt fastOptJS
Then, launch the app with Expo
$ npm start
Production Bundles
To create a minified app, first build an optimized Scala.js bundle
$ sbt fullOptJS
Then, go to App.js
and uncomment module.exports = require("./target/scala-2.12/app-opt.js").app;
in order to enable the production bundle. Finally, switch Expo to production mode to load your production app.
Ejecting
If you need to develop your app without depending on Expo, you can eject at any time by running npm run eject
. This gives you the option to either eject to a "bare" project that uses React Native's build tooling or to an unmanaged ExpoKit project that still uses Expo but lets you add in custom native dependencies.
