prompt-for

Prompt the user for a series of answers.

Installation

$ npm install prompt-for

Example

var prompt = require('prompt-for');

var schema = {
  name: 'string',
  siblings: 'number',
  birthday: 'date',
  deceased: 'boolean',
  secret: 'password'
};

prompt(schema, function(err, answers){
  assert(answers.name == 'Ian');
  assert(answers.siblings == 2);
  assert(answers.birthday.getTime() == 1343260800000);
  assert(answers.deceased == false);
  assert(answers.secret == '1234');
});

And if you're being lazy...

prompt(['name', 'website'], function(err, answers){
  assert(answers.name == 'Ian');
  assert(answers.website == 'ianstormtaylor.com');
});

Or even...

prompt('name', function(err, answers){
  assert(answers.name == 'Ian');
});

Options

Define or overwrite default values...

• Default boolean value is false
• Default date value is now

var prompt = require('prompt-for');

var schema = {
  name: {type:'string', default:'Ian'},
  siblings: {type:'number', default:42},
  birthday: {type:'date', default:'yesterday'},
  deceased: {type:'boolean', default:true},
  secret: {type:'password', default:'1234'}
};

prompt(schema, function(err, answers){
  assert(answers.name == 'Ian');
  // ...
});

Disable required for string and number...

By default, empty or incorrect answers when asked a string or a number, will be asked again. Set required to false allows you to skip the question.

var prompt = require('prompt-for');

var schema = {
  name: {type:'string', required:false},
  siblings: {type:'number', required:false}
};

prompt(schema, function(err, answers){
  assert(answers.name == null);
  assert(answers.number == null);
});

API

prompt(schema, [options], fn)

Prompt the user with the given schema and optional options, then callback with fn(err, answers). Options default to:

{
  color: null,
  pad: true,
  prefix: '',
  separator: ': '
}
