Guide on how to programmatically assign a selected value to an answer using Inquirer

Currently, I'm utilizing inquirer to prompt a question to my users via the terminal:

var inquirer = require('inquirer');
var question = {
  name: 'name',
  message: '',
  validation: function(){ ... }
  filter: function(){ ... }
};

However, I also want to allow my users to input this field using the --name command line argument. (let's say arg.name)

The main issue is: How can I instruct inquirer to consider this arg.name value as if it was entered by the user as the response to this question.

Keep in mind that I require both the validation and filtering to be applied to this value. (for instance, if an invalid value is passed through --name, the user should see an error message and prompted to enter a new value)

I am optimistic that there is a solution to this dilemma without having to resort to manually calling my validation and filter methods.

Answer №1

If you want to assign a default value to a variable based on arg.name, you can do so like this:

let argument = args.name;        
const question = {
  name: 'name',
  message: 'Name?',
  default: argument
};

I tested this out and it worked perfectly. Users just need to press enter to use the name provided in the arguments. Make sure to inform them about this in the prompt. Additionally, remember that your validation will occur after your filters, so ensure that your filters align with your validation criteria.
