Currently, there is no requirements for an app's browser support. It is recommended that you adhere to the library standard when possible.

  • Development teams have independence to set standards
• Cons
  • Hub apps have an inconsistent browser experience
  • No reference for broswer support by apps
  • Complicates providing client support
  • Difficult to communicate expectations to clients

Adding IE 11 browser support

1. Delete: node_modules/.cache (to avoid issues with babel-loader)
2. Install the core-js and the polyfill (raf): npm install core-js@3 raf
3. Add the imports into your index.tsx (.jsx): core-js and raf/polyfill
4. Run the app: npm run start (or npm run dev if you are using the shell)
