Options

Property	Type	Required	Description
message	string	yes	The question to ask
choices	Array<{ value: string, name?: string, description?: string, disabled?: boolean | string } | Separator>	yes	List of the available choices. The value will be returned as the answer, and used as display if no name is defined. Choices who're disabled will be displayed, but not selectable. The description will be displayed under the prompt when the cursor land over the choice.
default	string	no	Defines in front of which item the cursor will initially appear. When omitted, the cursor will appear on the first selectable item.
pageSize	number	no	By default, lists of choice longer than 7 will be paginated. Use this option to control how many choices will appear on the screen at once.
loop	boolean	no	Defaults to true. When set to false, the cursor will be constrained to the top and bottom of the choice list without looping.
theme	See Theming	no	Customize look of the prompt.

The Separator object can be used to render non-selectable lines in the choice list. By default it'll render a line, but you can provide the text as argument (new Separator('-- Dependencies --')). This option is often used to add labels to groups within long list of options.

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;
    help: (text: string) => string;
    highlight: (text: string) => string;
    disabled: (text: string) => string;
  };
  icon: {
    cursor: string;
  };
  helpMode: 'always' | 'never' | 'auto';
};

theme.helpMode

• auto (default): Hide the help tips after an interaction occurs.
• always: The help tips will always show and never hide.
• never: The help tips will never show.
