Can't use in React Native

[tinaroh]

I'm trying to use this library in a React Native app for localization but I'm having trouble with the following error:

Error: Unable to resolve module `assert` from `/Users/tinaroh/Dev/Raha/raha-mobile-app/node_modules/cldr-data/index.js`: Module `assert` does not exist in the Haste module map

This might be related to https://github.com/facebook/react-native/issues/4968
To resolve try the following:
  1. Clear watchman watches: `watchman watch-del-all`.
  2. Delete the `node_modules` folder: `rm -rf node_modules && npm install`.
  3. Reset Metro Bundler cache: `rm -rf /tmp/metro-bundler-cache-*` or `npm start -- --reset-cache`.
  4. Remove haste cache: `rm -rf /tmp/haste-map-react-native-packager-*`.

I tried the listed workarounds in the mentioned issue but have had no luck.

For set up I did: yarn add react-globalize cldr-data (we use yarn instead of npm)

Initialization in the file with the component:

var ReactGlobalize = require("react-globalize");
var Globalize = require("globalize");
Globalize.load(require("cldr-data").entireSupplemental());
Globalize.load(require("cldr-data").entireMainFor("en", "de"));

Call-site in the render function within the same file:

{new Globalize("de").numberFormatter({ minimumFractionDigits: 2 })(10)}

(tried the static version too)

I'm pretty new to JavaScript/React. I heard that there are differences with the React Native JS and web JS, could that be what's tripping this up? Though I feel like assert should be in both... Is there something special I need to do for React Native?
