Created by jonschlinkert and doowb, Enquirer is fast, easy to use, and lightweight enough for small projects, while also being powerful and customizable enough for the most advanced use cases.

Fast - Loads in ~4ms (that's about 3-4 times faster than a single frame of a HD movie at 60fps)
Lightweight - Only one dependency, the excellent ansi-colors by Brian Woodward.
Easy to implement - Uses promises and async/await and sensible defaults to make prompts easy to create and implement.
Easy to use - Thrill your users with a better experience! Navigating around input and choices is a breeze. You can even create quizzes, or record and playback key bindings to aid with tutorials and videos.
Intuitive - Keypress combos are available to simplify usage.
Flexible - All prompts can be used standalone or chained together.
Stylish - Easily override semantic styles and symbols for any part of the prompt.
Extensible - Easily create and use custom prompts by extending Enquirer's built-in prompts.
Pluggable - Add advanced features to Enquirer using plugins.
Validation - Optionally validate user input with any prompt.
Well tested - All prompts are well-tested, and tests are easy to create without having to use brittle, hacky solutions to spy on prompts or "inject" values.
Examples - There are numerous examples available to help you get started.

About

❯ Install

Install with npm:

npm install enquirer --save

Install with yarn:

yarn add enquirer

(Requires Node.js 8.6 or higher. Please let us know if you need support for an earlier version by creating an issue.)

❯ Usage

Single prompt

The easiest way to get started with enquirer is to pass a question object to the prompt method.

const { prompt } = require('enquirer');

const response = await prompt({
  type: 'input',
  name: 'username',
  message: 'What is your username?'
});

console.log(response); // { username: 'jonschlinkert' }

(Examples with await need to be run inside an async function)

Multiple prompts

Pass an array of "question" objects to run a series of prompts.

const response = await prompt([
  {
    type: 'input',
    name: 'name',
    message: 'What is your name?'
  },
  {
    type: 'input',
    name: 'username',
    message: 'What is your username?'
  }
]);

console.log(response); // { name: 'Edward Chan', username: 'edwardmchan' }

Different ways to run enquirer

1. By importing the specific `built-in prompt`

const { Confirm } = require('enquirer');

const prompt = new Confirm({
  name: 'question',
  message: 'Did you like enquirer?'
});

prompt.run()
  .then(answer => console.log('Answer:', answer));

2. By passing the options to `prompt`

const { prompt } = require('enquirer');

prompt({
  type: 'confirm',
  name: 'question',
  message: 'Did you like enquirer?'
})
  .then(answer => console.log('Answer:', answer));

❯ Enquirer

Enquirer is a prompt runner

Add Enquirer to your JavaScript project with following line of code.

const Enquirer = require('enquirer');

The main export of this library is the Enquirer class, which has methods and features designed to simplify running prompts.

const { prompt } = require('enquirer');
const questions = [
  {
    type: 'input',
    name: 'username',
    message: 'What is your username?'
  },
  {
    type: 'password',
    name: 'password',
    message: 'What is your password?'
  }
];

const answers = await prompt(questions);
console.log(answers);

Prompts control how values are rendered and returned

Each individual prompt is a class with special features and functionality for rendering the types of values you want to show users in the terminal, and subsequently returning the types of values you need to use in your application.

How can I customize prompts?

Below in this guide you will find information about creating custom prompts. For now, we'll focus on how to customize an existing prompt.

All of the individual prompt classes in this library are exposed as static properties on Enquirer. This allows them to be used directly without using enquirer.prompt().

Use this approach if you need to modify a prompt instance, or listen for events on the prompt.

Example

const { Input } = require('enquirer');
const prompt = new Input({
  name: 'username',
  message: 'What is your username?'
});

prompt.run()
  .then(answer => console.log('Username:', answer))
  .catch(console.error);

Enquirer

Create an instance of Enquirer.

Params

options {Object}: (optional) Options to use with all prompts.
answers {Object}: (optional) Answers object to initialize with.

Example

const Enquirer = require('enquirer');
const enquirer = new Enquirer();

register()

Params

type {String}
fn {Function|Prompt}: Prompt class, or a function that returns a Prompt class.
returns {Object}: Returns the Enquirer instance

Example

const Enquirer = require('enquirer');
const enquirer = new Enquirer();
enquirer.register('customType', require('./custom-prompt'));

prompt()

Prompt function that takes a "question" object or array of question objects, and returns an object with responses from the user.

Params

questions {Array|Object}: Options objects for one or more prompts to run.
returns {Promise}: Promise that returns an "answers" object with the user's responses.

Example

const Enquirer = require('enquirer');
const enquirer = new Enquirer();

const response = await enquirer.prompt({
  type: 'input',
  name: 'username',
  message: 'What is your username?'
});
console.log(response);

use()

Use an enquirer plugin.

Params

plugin {Function}: Plugin function that takes an instance of Enquirer.
returns {Object}: Returns the Enquirer instance.

Example

const Enquirer = require('enquirer');
const enquirer = new Enquirer();
const plugin = enquirer => {
  // do stuff to enquire instance
};
enquirer.use(plugin);

Enquirer#prompt

Prompt function that takes a "question" object or array of question objects, and returns an object with responses from the user.

Params

questions {Array|Object}: Options objects for one or more prompts to run.
returns {Promise}: Promise that returns an "answers" object with the user's responses.

Example

const { prompt } = require('enquirer');
const response = await prompt({
  type: 'input',
  name: 'username',
  message: 'What is your username?'
});
console.log(response);

❯ Prompts

This section is about Enquirer's prompts: what they look like, how they work, how to run them, available options, and how to customize the prompts or create your own prompt concept.

Getting started with Enquirer's prompts

Prompt - The base Prompt class used by other prompts
- Prompt Options
Built-in prompts
Prompt Types - The base Prompt class used by other prompts
Custom prompts - Enquirer 2.0 introduced the concept of prompt "types", with the goal of making custom prompts easier than ever to create and use.

Prompt

The base Prompt class is used to create all other prompts.

const { Prompt } = require('enquirer');
class MyCustomPrompt extends Prompt {}

See the documentation for creating custom prompts to learn more about how this works.

Prompt Options

Each prompt takes an options object (aka "question" object), that implements the following interface:

{
  // required
  type: string | function,
  name: string | function,
  message: string | function | async function,

  // optional
  skip: boolean | function | async function,
  initial: string | function | async function,
  format: function | async function,
  result: function | async function,
  validate: function | async function,
}

Each property of the options object is described below:

Property	Required?	Type	Description
`type`	yes	`string\|function`	Enquirer uses this value to determine the type of prompt to run, but it's optional when prompts are run directly.
`name`	yes	`string\|function`	Used as the key for the answer on the returned values (answers) object.
`message`	yes	`string\|function`	The message to display when the prompt is rendered in the terminal.
`skip`	no	`boolean\|function`	If `true` it will not ask that prompt.
`initial`	no	`string\|function`	The default value to return if the user does not supply a value.
`format`	no	`function`	Function to format user input in the terminal.
`result`	no	`function`	Function to format the final submitted value before it's returned.
`validate`	no	`function`	Function to validate the submitted value before it's returned. This function may return a boolean or a string. If a string is returned it will be used as the validation error message.

Example usage

const { prompt } = require('enquirer');

const question = {
  type: 'input',
  name: 'username',
  message: 'What is your username?'
};

prompt(question)
  .then(answer => console.log('Answer:', answer))
  .catch(console.error);

BasicAuth Prompt

Prompt that asks for username and password to authenticate the user. The default implementation of authenticate function in BasicAuth prompt is to compare the username and password with the values supplied while running the prompt.

Example Usage

const { BasicAuth } = require('enquirer');

 const prompt = new BasicAuth({
  name: 'password',
  message: 'Please enter your password',
  username: 'rajat-sr',
  password: '123',

Prompt Types

There are 5 (soon to be 6!) type classes:

ArrayPrompt
AuthPrompt
BooleanPrompt
DatePrompt (Coming Soon!)
NumberPrompt
StringPrompt

Each type is a low-level class that may be used as a starting point for creating higher level prompts. Continue reading to learn how.

ArrayPrompt

The ArrayPrompt class is used for creating prompts that display a list of choices in the terminal. For example, Enquirer uses this class as the basis for the Select and Survey prompts.

Options

In addition to the options available to all prompts, Array prompts also support the following options.

Option	Required?	Type	Description
`autofocus`	`no`	`string\|number`	The index or name of the choice that should have focus when the prompt loads. Only one choice may have focus at a time.
`stdin`	`no`	`stream`	The input stream to use for emitting keypress events. Defaults to `process.stdin`.
`stdout`	`no`	`stream`	The output stream to use for writing the prompt to the terminal. Defaults to `process.stdout`.

Properties

Array prompts have the following instance properties and getters.

Property name	Type	Description
`choices`	`array`	Array of choices that have been normalized from choices passed on the prompt options.
`cursor`	`number`	Position of the cursor relative to the user input (string).
`enabled`	`array`	Returns an array of enabled choices.
`focused`	`array`	Returns the currently selected choice in the visible list of choices. This is similar to the concept of focus in HTML and CSS. Focused choices are always visible (on-screen). When a list of choices is longer than the list of visible choices, and an off-screen choice is focused, the list will scroll to the focused choice and re-render.
`focused`	Gets the currently selected choice. Equivalent to `prompt.choices[prompt.index]`.
`index`	`number`	Position of the pointer in the visible list (array) of choices.
`limit`	`number`	The number of choices to display on-screen.
`selected`	`array`	Either a list of enabled choices (when `options.multiple` is true) or the currently focused choice.
`visible`	`string`

Methods

Method	Description
`pointer()`	Returns the visual symbol to use to identify the choice that currently has focus. The `❯` symbol is often used for this. The pointer is not always visible, as with the `autocomplete` prompt.
`indicator()`	Returns the visual symbol that indicates whether or not a choice is checked/enabled.
`focus()`	Sets focus on a choice, if it can be focused.

Choices

Array prompts support the choices option, which is the array of choices users will be able to select from when rendered in the terminal.

Type: string|object

Example

const { prompt } = require('enquirer');

const questions = [{
  type: 'select',
  name: 'color',
  message: 'Favorite color?',
  initial: 1,
  choices: [
    { name: 'red',   message: 'Red',   value: '#ff0000' }, //<= choice object
    { name: 'green', message: 'Green', value: '#00ff00' }, //<= choice object
    { name: 'blue',  message: 'Blue',  value: '#0000ff' }  //<= choice object
  ]
}];

let answers = await prompt(questions);
console.log('Answer:', answers.color);

Defining choices

Whether defined as a string or object, choices are normalized to the following interface:

{
  name: string;
  message: string | undefined;
  value: string | undefined;
  hint: string | undefined;
  disabled: boolean | string | undefined;
}

Example

const question = {
  name: 'fruit',
  message: 'Favorite fruit?',
  choices: ['Apple', 'Orange', 'Raspberry']
};

Normalizes to the following when the prompt is run:

const question = {
  name: 'fruit',
  message: 'Favorite fruit?',
  choices: [
    { name: 'Apple', message: 'Apple', value: 'Apple' },
    { name: 'Orange', message: 'Orange', value: 'Orange' },
    { name: 'Raspberry', message: 'Raspberry', value: 'Raspberry' }
  ]
};

Choice properties

The following properties are supported on choice objects.

Option	Type	Description
`name`	`string`	The unique key to identify a choice
`message`	`string`	The message to display in the terminal. `name` is used when this is undefined.
`value`	`string`	Value to associate with the choice. Useful for creating key-value pairs from user choices. `name` is used when this is undefined.
`choices`	`array`	Array of "child" choices.
`hint`	`string`	Help message to display next to a choice.
`role`	`string`	Determines how the choice will be displayed. Currently the only role supported is `separator`. Additional roles may be added in the future (like `heading`, etc). Please create a [feature request]
`enabled`	`boolean`	Enabled a choice by default. This is only supported when `options.multiple` is true or on prompts that support multiple choices, like MultiSelect.
`disabled`	`boolean\|string`	Disable a choice so that it cannot be selected. This value may either be `true`, `false`, or a message to display.
`indicator`	`string\|function`	Custom indicator to render for a choice (like a check or radio button).

AuthPrompt

The AuthPrompt is used to create prompts to log in user using any authentication method. For example, Enquirer uses this class as the basis for the BasicAuth Prompt. You can also find prompt examples in examples/auth/ folder that utilizes AuthPrompt to create OAuth based authentication prompt or a prompt that authenticates using time-based OTP, among others.

AuthPrompt has a factory function that creates an instance of AuthPrompt class and it expects an authenticate function, as an argument, which overrides the authenticate function of the AuthPrompt class.

Methods

Method	Description
`authenticate()`	Contain all the authentication logic. This function should be overridden to implement custom authentication logic. The default `authenticate` function throws an error if no other function is provided.

Choices

Auth prompt supports the choices option, which is the similar to the choices used in Form Prompt.

Example

const { AuthPrompt } = require('enquirer');

function authenticate(value, state) {
  if (value.username === this.options.username && value.password === this.options.password) {
    return true;
  }
  return false;
}

const CustomAuthPrompt = AuthPrompt.create(authenticate);

const prompt = new CustomAuthPrompt({
  name: 'password',
  message: 'Please enter your password',
  username: 'rajat-sr',
  password: '1234567',
  choices: [
    { name: 'username', message: 'username' },
    { name: 'password', message: 'password' }
  ]
});

prompt
  .run()
  .then(answer => console.log('Authenticated?', answer))
  .catch(console.error);

BooleanPrompt

The BooleanPrompt class is used for creating prompts that display and return a boolean value.

const { BooleanPrompt } = require('enquirer');

const  prompt = new  BooleanPrompt({
  header:  '========================',
  message:  'Do you love enquirer?',
  footer:  '========================',
});

prompt.run()
  .then(answer  =>  console.log('Selected:', answer))
  .catch(console.error);

Returns: boolean

NumberPrompt

The NumberPrompt class is used for creating prompts that display and return a numerical value.

const { NumberPrompt } = require('enquirer');

const  prompt = new  NumberPrompt({
  header:  '************************',
  message:  'Input the Numbers:',
  footer:  '************************',
});

prompt.run()
  .then(answer  =>  console.log('Numbers are:', answer))
  .catch(console.error);

Returns: string|number (number, or number formatted as a string)

StringPrompt

The StringPrompt class is used for creating prompts that display and return a string value.

const { StringPrompt } = require('enquirer');

const prompt = new StringPrompt({
  header: '************************',
  message: 'Input the String:',
  footer: '************************'
});

prompt.run()
  .then(answer => console.log('String is:', answer))
  .catch(console.error);

Returns: string

❯ Custom prompts

With Enquirer 2.0, custom prompts are easier than ever to create and use.

How do I create a custom prompt?

Custom prompts are created by extending either:

Enquirer's Prompt class
one of the built-in prompts, or
low-level types.

const { Prompt } = require('enquirer');

class HaiKarate extends Prompt {
  constructor(options = {}) {
    super(options);
    this.value = options.initial || 0;
    this.cursorHide();
  }
  up() {
    this.value++;
    this.render();
  }
  down() {
    this.value--;
    this.render();
  }
  render() {
    this.clear(); // clear previously rendered prompt from the terminal
    this.write(`${this.state.message}: ${this.value}`);
  }
}

// Use the prompt by creating an instance of your custom prompt class.
const prompt = new HaiKarate({
  message: 'How many sprays do you want?',
  initial: 10
});

prompt.run()
  .then(answer => console.log('Sprays:', answer))
  .catch(console.error);

If you want to be able to specify your prompt by type so that it may be used alongside other prompts, you will need to first create an instance of Enquirer.

const Enquirer = require('enquirer');
const enquirer = new Enquirer();

Then use the .register() method to add your custom prompt.

enquirer.register('haikarate', HaiKarate);

Now you can do the following when defining "questions".

let spritzer = require('cologne-drone');
let answers = await enquirer.prompt([
  {
    type: 'haikarate',
    name: 'cologne',
    message: 'How many sprays do you need?',
    initial: 10,
    async onSubmit(name, value) {
      await spritzer.activate(value); //<= activate drone
      return value;
    }
  }
]);
