  test: string;
  books: object[];
  roles: object[];

I also have this error. Any news about this problem

Another simple example:

export interface IClientConfiguration {
  production: boolean;
  groupChat: boolean;
}

type ConfigKeys = keyof IClientConfiguration;

configs.zip

The current v10 release also does not support the as operator, meaning you get stuff like this in JSX:

/Users/dvlpr/dev/myproj/src/appinfo/AppInfoScreen.tsx
  57:43  error  Parsing error: Unexpected token, expected ";"

  55 | const clickHandler = (e: MouseEvent) => {
  56 |     const input: HTMLTextAreaElement = document.createElement('textarea');
> 57 |     const currentTarget = e.currentTarget as HTMLDivElement;
     |                                           ^

The good news is that upgrading to babel-eslint@next (v11 beta) seems to fix this, but it no longer handles type definitions , so you get a whole new batch of issues: #760
