Platform-specific extensions

I’m trying to get platform-specific extensions working by following the instructions here - I’ve got a blank typescript project created with expo init

I’ve added two files


which both simply export default 42

I’m trying to use this from within App.tsx

import BigButton from './BigButton';
console.log('BigButton', BigButton)

I get the following error message:
Failed to compile

D:/temp/expo_tryout/second-project/App.tsxModule not found: Can't resolve './BigButton' in 'D:\temp\expo_tryout\second-project'

If i change the import to refer to either android or ios explicitly it works

Why isn’t the build process picking up the files?

expo diagnostics:

Expo CLI 3.4.1 environment info:
OS: Windows 10
Yarn: 1.17.3 - C:\Program Files (x86)\Yarn\bin\yarn.CMD
npm: 6.9.0 - C:\Program Files\nodejs\npm.CMD

Hey @wallaceturner,

It looks like this is a known TypeScript behavior. It seems that platform extensions are not supported as of yet.
