This project is a simple Expo-based React Native app using TypeScript (for UI templates) and Kotlin.

Getting Started

• Follow the instructions from https://docs.expo.io/versions/latest/introduction/installation to set up the dev environment.
• Run npm install in the app folder.

This project is pre-configured for both IntelliJ and Visual Studio Code.

IntelliJ

• In Preferences -> Language & Frameworks -> Node.js and NPM, configure the Node interpreter.
• Use "Start" Run/Debug configuration to run or debug the app.
• Follow the onscreen instructions from the Expo tool.

Visual Studio Code

• Use the task "Expo: start ios" or "Expo: start android" to run the app.
• Use "Debug in Exponent" to debug the app in VSCode. The running bundler (started from one of the tasks mentioned above) needs to be stopped first.

Limitations

• Kotlin SourceMap only works in VSCode but not in IntelliJ (v2018.3.5) - https://youtrack.jetbrains.com/issue/KT-29944
• In both IntelliJ and VSCode, to set a breakpoint in Kotlin code, we have to use js("debugger").
• We have to declare ambient modules manually for the JavaScript code generated from the Kotlin code.
