[miroslavstastny]

Bug Report

Steps

Create react app:

npx create-react-app stardust-consumer --typescript

Add stardust package, Provider, Button, run the app

Expected Result

Works

Actual Result

App fails to compile because of the two following errors 💣

1. FocusZone (under our control):

/stardust-consumer/node_modules/@stardust-ui/react/dist/es/lib/accessibility/FocusZone/FocusZone.types.d.ts
Type error: Ambient const enums are not allowed when the '--isolatedModules' flag is provided.  TS1209

    114 |     preventDefaultWhenHandled?: boolean;
    115 | }
  > 116 | export declare const enum FocusZoneTabbableElements {
        |                           ^
    117 |     /** Tabbing is not allowed */
    118 |     none = 0,
    119 |     /** All tabbing action is allowed */

2. Fela (out of our control, currently in all Fela version, up to 10.0.1):

stardust-consumer/node_modules/@stardust-ui/react/node_modules/fela/index.d.ts
Type error: Ambient const enums are not allowed when the '--isolatedModules' flag is provided.  TS1209

    11 |   type TEnhancer = (renderer: IRenderer) => IRenderer; //http://fela.js.org/docs/advanced/Enhancers.html
    12 | 
  > 13 |   const enum TSubscribeMessageType {
       |              ^
    14 |     rule = 'RULE',
    15 |     staticObject = 'RULE',
    16 |     keyframes = 'KEYFRAME',

Version

0.14.0

Why this is important

• create-react-app is the essential way how to create the project
• it is not possible to disable --isolatedModules there

We cannot build project with Babel because it also not working with const enum: https://babeljs.io/docs/en/babel-plugin-transform-typescript
