Running the project

Running the project is as simple as running

npm run start

This runs the start script specified in our package.json, and will spawn off a server which reloads the page as we save our files. Typically the server runs at http://localhost:8080, but should be automatically opened for you.

Testing the project

Testing is also just a command away:

npm test

Writing tests with Jest

We've created test examples with jest-ts in src/components/screen/__tests__ and src/components/shared/__tests__. Since react is component oriented, we've designed to focus on writing test in same level of directory with component. You can simply run npm test to test if it succeeds and look more closer opening the source.

Localization

We've defined Localization strings in STRINGS.js which is in root dir. We used react-native-localization pacakage for this one.

import LocalizedStrings from 'react-native-localization';

const strings = new LocalizedStrings({
  en: {
    LOGIN: 'Login',
  },
  kr: {
    LOGIN: '로그인',
  },
});

export {
  strings,
};

Fixed jest setup by adding following in jestSetup.

import { NativeModules } from 'react-native';

/**
 * monkey patching the locale to avoid the error:
 * Something went wrong initializing the native ReactLocalization module
 * https://gist.github.com/MoOx/08b465c3eac9e36e683929532472d1e0
 */

NativeModules.ReactLocalization = {
  language: 'en_US',
};
