Enquirer Overview

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);
