Question-helper NPM

Template helper that asks a question in the command line and resolves the template with the answer.

Inspired by conversations with Jon Schlinkert

Install with npm

$ npm i question-helper --save

Usage

var question = require('question-helper');

// Prompt a user for a question and get an answer back.
question("What's your name?", function (err, answer) {
  console.log(chalk.green("Hi %s!"), answer);
});

Params

key {String}: Either a key on a questions object on the context or a question to ask.
options {String}: Additional options to pass.
callback {Function}: Callback function that will be passed an error and/or the results of asking the question.

Examples

Pass a questions object, where the value of each property is a question to ask:

var context = {
  questions: {
    name: 'What is your name?',
    description: 'Project description?',
    author: {
      name: 'Author name?',
      url: 'Author url?',
    }
  }
};

// Q: 'What is your name?'
question('name', context, function (err, answer) {
  if (err) console.log(err);
  // A: 'Jon'
});

// Q: 'Project description?'
question('description', context, function (err, answer) {
  if (err) console.log(err);
  // A: 'Template helper that asks a question...'
});

// Q: 'Author name?'
question('author.name', context, function (err, answer) {
  if (err) console.log(err);
  // A: 'Brian Woodward'
});
