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.
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 byawait expand()
. -
name
: The string displayed in the choice list. It'll default to the stringifyvalue
. -
key
: The input the use must provide to select the choice. Must be a lowercase single alpha-numeric character string.
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.
