Options

Property	Type	Required	Description
message	string	yes	The question to ask
choices	Choice[]	yes	Array of the different allowed choices. The h/help option is always provided by default
default	string	no	Default choices to be selected. (value must be one of the choices key)
expanded	boolean	no	Expand the choices by default
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;
  key: string;
};

Here's each property:

• value: The value is what will be returned by await expand().
• name: The string displayed in the choice list. It'll default to the stringify value.
• key: The input the use must provide to select the choice. Must be a lowercase single alpha-numeric character string.

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;
    defaultAnswer: (text: string) => string;
    highlight: (text: string) => string;
  };
};
