Theming

You can theme a prompt by passing a theme object option. The theme object only need to includes the keys you wish to modify, we'll fallback on the defaults for the rest.

type Theme = {
  prefix: string;
  spinner: {
    interval: number;
    frames: string[];
  };
  style: {
    answer: (text: string) => string;
    message: (text: string) => string;
    error: (text: string) => string;
    defaultAnswer: (text: string) => string;
    highlight: (text: string) => string;
  };
};
