Options

Property	Type	Required	Description
message	string	yes	The question to ask
choices	Choice[]	yes	List of the available choices.
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.

Separator objects can be used in the choices array 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.

Choice object

The Choice object is typed as

type Choice<Value> = {
  value: Value;
  name?: string;
  description?: string;
  short?: string;
  disabled?: boolean | string;
};

Here's each property:

• value: The value is what will be returned by await select().
• name: This is the string displayed in the choice list.
• description: Option for a longer description string that'll appear under the list when the cursor highlight a given choice.
• short: Once the prompt is done (press enter), we'll use short if defined to render next to the question. By default we'll use name.
• disabled: Disallow the option from being selected. If disabled is a string, it'll be used as a help tip explaining why the choice isn't available.

choices can also be an array of string, in which case the string will be used both as the value and the name.

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 | { idle: string; done: string };
  spinner: {
    interval: number;
    frames: string[];
  };
  style: {
    answer: (text: string) => string;
    message: (text: string, status: 'idle' | 'done' | 'loading') => string;
    error: (text: string) => string;
    help: (text: string) => string;
    highlight: (text: string) => string;
    description: (text: string) => string;
    disabled: (text: string) => string;
    keysHelpTip: (keys: [key: string, action: string][]) => string | undefined;
  };
  icon: {
    cursor: string;
  };
  indexMode: 'hidden' | 'number';
};

theme.style.keysHelpTip

This function allows you to customize the keyboard shortcuts help tip displayed below the prompt. It receives an array of key-action pairs and should return a formatted string. You can also hook here to localize the labels to different languages.

It can also returns undefined to hide the help tip entirely. This is the replacement for the deprecated theme option helpMode: 'never'.

theme: {
  style: {
    keysHelpTip: (keys) => {
      // Return undefined to hide the help tip completely.
      return undefined;

      // Or customize the formatting. Or localize the labels.
      return keys.map(([key, action]) => `${key}: ${action}`).join(' | ');
    };
  }
}

theme.indexMode

Controls how indices are displayed before each choice:

• hidden (default): No indices are shown
• number: Display a number before each choice (e.g. "1. Option A")
