Technologies used:

  1. Google Sheets: for data source.
  2. Google App Script (in JavaScript): for analysing raw data to rank currencies strongest to weakest and sends results from Google Sheets to Google’s Firebase.
  3. Firebase (stores data in json): database source for App authentication and data source.
  4. React Native App (reads JavaScript): for developing an App compatible for iOS and Android.
  5. Redux: for state management.

Custom code (excluding libraries and dependencies):

  1. ./src directory
  2. ./GoogleAppScript.js
  3. ./index.js

The Google App Script is included in the ./GoogleAppScript.js file.

Personal Firebase Realtime database code has been removed for privacy from:

  1. ./src/App.js = configuration code
  2. ./GoogleAppScript.js = database secret

Dependencies used:

Listed in the ./package.json file.
