Prompt the user for a series of answers.
$ npm install prompt-for
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');
});Define or overwrite default values...
- Default
booleanvalue is false - Default
datevalue 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);
});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: ': '
