Cannot use import statement outside a module in app.config.js

Expo SDK
1

This documentation link makes it seem like you can import in app.config.js

But when I import Constants and try to build, I get an error:

import Constants from 'expo-constants';
const releaseChannel = Constants.manifest.releaseChannel;

if (releaseChannel === undefined) {
  // some stuff
}

export default ({ config }) => {
  return {
    ...config,
    extra: extraConfig,
  };
};

Hey @mcgintech, this is the expected behavior. The documentation refers to the expo/config package that is designed to be used within app.config.js/ts files.

Cheers,
