Get started with Enquirer, the most powerful and easy-to-use Node.js library for creating interactive CLI prompts.
Install withnpm:
npm install enquirer --save
Install withyarn:
yarn add enquirer
(Requires Node.js 8.6 or higher. Please let us know if you need support for an earlier version by creating anissue.)
The easiest way to get started with enquirer is to pass aquestion object to theprompt
method.
const{ prompt}=require('enquirer');constresponse=awaitprompt({type:'input',name:'username',message:'What is your username?'});console.log(response);// { username: 'jonschlinkert' }
(Examples withawait
need to be run inside anasync
function)
Pass an array of"question" objects to run a series of prompts.
constresponse=awaitprompt([{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' }
const{ Confirm}=require('enquirer');constprompt=newConfirm({name:'question',message:'Did you like enquirer?'});prompt.run().then(answer=>console.log('Answer:',answer));
const{ prompt}=require('enquirer');prompt({type:'confirm',name:'question',message:'Did you like enquirer?'}).then(answer=>console.log('Answer:',answer));

Enquirer is a prompt runner
Add Enquirer to your JavaScript project with following line of code.
constEnquirer=require('enquirer');
The main export of this library is theEnquirer
class, which has methods and features designed to simplify running prompts.
const{ prompt}=require('enquirer');constquestions=[{type:'input',name:'username',message:'What is your username?'},{type:'password',name:'password',message:'What is your password?'}];constanswers=awaitprompt(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 creatingcustom prompts. For now, we'll focus on how to customize an existing prompt.
All of the individualprompt classes in this library are exposed as static properties on Enquirer. This allows them to be used directly without usingenquirer.prompt()
.
Use this approach if you need to modify a prompt instance, or listen for events on the prompt.
Example
const{ Input}=require('enquirer');constprompt=newInput({name:'username',message:'What is your username?'});prompt.run().then(answer=>console.log('Username:',answer)).catch(console.error);
Create an instance ofEnquirer
.
Params
options
{Object}: (optional) Options to use with all prompts.answers
{Object}: (optional) Answers object to initialize with.
Example
constEnquirer=require('enquirer');constenquirer=newEnquirer();
Register a custom prompt type.
Params
type
{String}fn
{Function|Prompt}:Prompt
class, or a function that returns aPrompt
class.returns
{Object}: Returns the Enquirer instance
Example
constEnquirer=require('enquirer');constenquirer=newEnquirer();enquirer.register('customType',require('./custom-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
constEnquirer=require('enquirer');constenquirer=newEnquirer();constresponse=awaitenquirer.prompt({type:'input',name:'username',message:'What is your username?'});console.log(response);
Use an enquirer plugin.
Params
plugin
{Function}: Plugin function that takes an instance of Enquirer.returns
{Object}: Returns the Enquirer instance.
Example
constEnquirer=require('enquirer');constenquirer=newEnquirer();constplugin=enquirer=>{// do stuff to enquire instance};enquirer.use(plugin);
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');constresponse=awaitprompt({type:'input',name:'username',message:'What is your username?'});console.log(response);
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 - 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.
The basePrompt
class is used to create all other prompts.
const{ Prompt}=require('enquirer');classMyCustomPromptextendsPrompt{}
See the documentation forcreating custom prompts to learn more about how this works.
Each prompt takes an options object (aka "question" object), that implements the following interface:
{// requiredtype:string|function,name:string|function,message:string|function|asyncfunction,// optionalskip:boolean|function|asyncfunction,initial:string|function|asyncfunction,format:function|asyncfunction,result:function|asyncfunction,validate:function|asyncfunction,}
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 | Iftrue 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');constquestion={type:'input',name:'username',message:'What is your username?'};prompt(question).then(answer=>console.log('Answer:',answer)).catch(console.error);

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.
TheArrayPrompt
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 theSelect andSurvey prompts.
In addition to theoptions 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 toprocess.stdin . |
stdout | no | stream | The output stream to use for writing the prompt to the terminal. Defaults toprocess.stdout . |
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 theuser 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 isfocused, the list will scroll to the focused choice and re-render. |
focused | Gets the currently selected choice. Equivalent toprompt.choices[prompt.index] . | |
index | number | Position of the pointer in thevisible list (array) of choices. |
limit | number | The number of choices to display on-screen. |
selected | array | Either a list of enabled choices (whenoptions.multiple is true) or the currently focused choice. |
visible | string |
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 theautocomplete 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. |
Array prompts support thechoices
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');constquestions=[{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]}];letanswers=awaitprompt(questions);console.log('Answer:',answers.color);
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
constquestion={name:'fruit',message:'Favorite fruit?',choices:['Apple','Orange','Raspberry']};
Normalizes to the following when the prompt is run:
constquestion={name:'fruit',message:'Favorite fruit?',choices:[{name:'Apple',message:'Apple',value:'Apple'},{name:'Orange',message:'Orange',value:'Orange'},{name:'Raspberry',message:'Raspberry',value:'Raspberry'}]};
The following properties are supported onchoice
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 isseparator . Additional roles may be added in the future (likeheading , etc). Please create a [feature request] |
enabled | boolean | Enabled a choice by default. This is only supported whenoptions.multiple is true or on prompts that support multiple choices, likeMultiSelect. |
disabled | boolean|string | Disable a choice so that it cannot be selected. This value may either betrue ,false , or a message to display. |
indicator | string|function | Custom indicator to render for a choice (like a check or radio button). |
TheAuthPrompt
is used to create prompts to log in user using any authentication method. For example, Enquirer uses this class as the basis for theBasicAuth Prompt. You can also find prompt examples inexamples/auth/
folder that utilizesAuthPrompt
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 ofAuthPrompt
class and it expects anauthenticate
function, as an argument, which overrides theauthenticate
function of theAuthPrompt
class.
Method | Description |
---|---|
authenticate() | Contain all the authentication logic. This function should be overridden to implement custom authentication logic. The defaultauthenticate function throws an error if no other function is provided. |
Auth prompt supports thechoices
option, which is the similar to the choices used inForm Prompt.
Example
const{ AuthPrompt}=require('enquirer');functionauthenticate(value,state){if(value.username===this.options.username&&value.password===this.options.password){returntrue;}returnfalse;}constCustomAuthPrompt=AuthPrompt.create(authenticate);constprompt=newCustomAuthPrompt({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);
TheBooleanPrompt
class is used for creating prompts that display and return a boolean value.
const{ BooleanPrompt}=require('enquirer');constprompt=newBooleanPrompt({header:'========================',message:'Do you love enquirer?',footer:'========================',});prompt.run().then(answer=>console.log('Selected:',answer)).catch(console.error);
Returns:boolean
TheNumberPrompt
class is used for creating prompts that display and return a numerical value.
const{ NumberPrompt}=require('enquirer');constprompt=newNumberPrompt({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)
TheStringPrompt
class is used for creating prompts that display and return a string value.
const{ StringPrompt}=require('enquirer');constprompt=newStringPrompt({header:'************************',message:'Input the String:',footer:'************************'});prompt.run().then(answer=>console.log('String is:',answer)).catch(console.error);
Returns:string
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:
const{ Prompt}=require('enquirer');classHaiKarateextendsPrompt{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 terminalthis.write(`${this.state.message}:${this.value}`);}}// Use the prompt by creating an instance of your custom prompt class.constprompt=newHaiKarate({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 bytype
so that it may be used alongside other prompts, you will need to first create an instance ofEnquirer
.
constEnquirer=require('enquirer');constenquirer=newEnquirer();
Then use the.register()
method to add your custom prompt.
enquirer.register('haikarate',HaiKarate);
Now you can do the following when defining "questions".
letspritzer=require('cologne-drone');letanswers=awaitenquirer.prompt([{type:'haikarate',name:'cologne',message:'How many sprays do you need?',initial:10,asynconSubmit(name,value){awaitspritzer.activate(value);//<= activate dronereturnvalue;}}]);
These key combinations may be used with all prompts.
command | description |
---|---|
ctrl +c | Cancel the prompt. |
ctrl +g | Reset the prompt to its initial state. |
These combinations may be used on prompts that support user input (eg.input prompt,password prompt, andinvisible prompt).
command | description |
---|---|
left | Move the cursor back one character. |
right | Move the cursor forward one character. |
ctrl +a | Move cursor to the start of the line |
ctrl +e | Move cursor to the end of the line |
