[Question]: How do I check if the prompt is cancelled when it is cancelled after the first prompt?

[DomiDenie]

When the prompt is cancelled during the first question the response object is empty, but when it is cancelled later in the chain of prompts. The answers that are collected till that point are returned. Is there a way to blank this out onCancel?

The only avalible callback at the moment is https://github.com/terkelg/prompts#optionsoncancel. Maybe you can get creative with the onState change callback https://github.com/terkelg/prompts#onstate

Is there a way to blank this out onCancel?

@DomiDenie Yes. There are a couple of ways to do that using onCancel callback.

• Adding custom attribute to the answers object (I prefer this option)
• Deleting existing answers from the answers object.

// custom attribute
const prompts = require('prompts');

(async () => {
  const questions = [{ ... }];
  const onCancel = (prompt, answers) => {
    answers.__cancelled__ = true;
    return false;
  }

  const response = await prompts(questions, { onCancel });

  if (response.__cancelled__) {
    // handle cancellation
    return;
  }

  // process the response
})();

// delete existing answers
const prompts = require('prompts');

(async () => {
  const questions = [{ ... }];
  const onCancel = (prompt, answers) => {
    Object.keys(answers).forEach(answer => delete answers[answer]);

    return false;
  }

  const response = await prompts(questions, { onCancel });

  if (!Object.keys(response).length) {
    // handle cancellation
    return;
  }

  // process the response
})();
