Interrogation

A tiny library that allows you to ask a series of questions to the user in the console.

Features

• Ask question
• Ask MCQ questions
• Get response from user
• Supports coloring

How it works

Install

npm install interrogation

Import the library

const interrogation = require('interrogation')

Ask a question

An array of questions is required for the use of the function getAnswersFor().

const interrogation = require('interrogation')

interrogation.getAnswersFor(['question1? ', 'question2? ']).then((value) => {
    console.log(value);
});

To ask a MCQ (multiple choice question), wrap your question and it's possible choices in an array and pass it to the getAnswersFor() function.

interrogation.getAnswersFor(['question1? ', 'question2? ', ['question3', ['choice1', 'choice2', 'choice3']]]).then((value) => {
  console.log(value);
});

Get response

The response of an interrogation is an array of objects structured like this :

[
  { question: 'Question1 ', response: 'Response1' },
  { question: 'Question2 ', response: 'Response2' },
  { question: 'Question3', response: '2' } // choice 2
]

Version ^0.1.0 : Create a file of questions

You can now create a json file of questions, encode these questions or decode them.

Create a question file

Just create a json file with questions structured like below:

[
  {
    "type": "simple-question",
    "label": "Question 1",
    "format": "string"
  },
  {
    "type": "simple-question",
    "label": "Question 2",
    "format": "string"
  },
  {
    "type": "one-choice-mcq",
    "label": "Question 3",
    "choices": ["Choice 1", "Choice 2", "Choice 3"]
  },
  {
    "type": "simple-question",
    "label": "Question 4",
    "format": "number"
  }
]

Encode a question file

You can encode questions by calling the encodeQuestions() function.

console.log(interrogation.encodeQuestions('json-question.json'));

The output is a base64 string.

Output

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

A new file (question.int) containing the output is also generated. You can then send this file to anyone interrested in answering your questions. This can be very useful for an investigation or a survey.

Decode question file

On the other side, the question.int file can be decoded by calling the decodeQuestions() function.

console.log(interrogation.decodeQuestions('question.int'));

Output

[
  {
    "type": "simple-question",
    "label": "Question 1",
    "format": "string"
  },
  {
    "type": "simple-question",
    "label": "Question 2",
    "format": "string"
  },
  {
    "type": "one-choice-mcq",
    "label": "Question 3",
    "choices": ["Choice 1", "Choice 2", "Choice 3"]
  },
  {
    "type": "simple-question",
    "label": "Question 4",
    "format": "number"
  }
]

You can also get answers for encoded file directly by calling the getAnswersForJson() function.

interrogation.getAnswersForJson('question.int').then((value) => {
  console.log(value);
});

Output

[
  { question: 'Question 1', response: 'Response 1' },
  { question: 'Question 2', response: 'Response 2' },
  { question: 'Question 3', response: '3' }, // Choice 3
  { question: 'Question 4', response: 'Response 4' }
]

Future updates

• Support of multiple choices.
• Send encoded files by e-mail.
• Develop a client to answer question (for non-developers).
