This is a react shell for the SPGI Platform MFE implementation

// Babel configuration adds polyfills for application code(excluding dependencies from node_modules)
// There are 2 options to fix dependencies compatibility issues:
// 1. Include only required core-js polyfills imports inside this file
// For example

import 'core-js/stable/promise';
import 'core-js/stable/array/find';

// It potentionally could improve bundle size, but it requires to handpick polyfills

// 2. Set @babel/preset-env config options "useBuiltIns" as "entry" and remove all core-js imports except
// import 'core-js/stable

// Bundle size could be bigger, but all needed polyfills will be included

// Additional polyfills

// Fetch
import 'whatwg-fetch';

// SVG external content polyfill
import svg4everybody from 'svg4everybody';
svg4everybody({
  polyfill: true, // polyfill <use> elements for External Content
});
