Options

Property	Type	Required	Description
message	`string`	yes	The question to ask
default	`string`	no	Default value if no answer is provided (press `backspace` to clear the default; press `tab` to inline the value for edits)
required	`boolean`	no	Defaults to `false`. If set to true, `undefined` (empty) will not be accepted for this.
transformer	`(string, { isFinal: boolean }) => string`	no	Transform/Format the raw value entered by the user. Once the prompt is completed, `isFinal` will be `true`. This function is purely visual, modify the answer in your code if needed.
validate	`string => boolean \\| string \\| Promise<boolean \\| string>`	no	On submit, validate the filtered answered content. When returning a string, it'll be used as the error message displayed to the user. Note: returning a rejected promise, we'll assume a code error happened and crash.
theme	See Theming	no	Customize look of the prompt.

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;
  };
  validationFailureMode: 'keep' | 'clear';
};

validationFailureMode defines the behavior of the prompt when the value submitted is invalid. By default, we'll keep the value allowing the user to edit it. When the theme option is set to clear, we'll remove and reset to an empty string.
