Options

extensions

TODO

• [x] Avoid multiple imports of classnames' dependency packages
• [x] Find a compatible solution for TS

declare namespace React {
  interface HTMLAttributes<any> extends AriaAttributes, DOMAttributes<any>  {
    className?: Record<string, boolean> | (string | Record<string, boolean>)[]
  }
}

• [x] Add excludes attributes
• [x] Add extensions attributes
• [ ] Unit Testing
