Creating phony passwords effortlessly in JavaScript utilizing the informal library

I am trying to create a password that meets the following criteria:

  • Minimum length: 7
  • Maximum length: 15
  • At least one uppercase letter
  • At least one lowercase letter
  • Special characters: ~ ! @ # $ % ^ * ( ) _ + ?

I have been using the casual library for generating passwords, but I'm having trouble including special characters. Can anyone provide assistance with this problem?

var casual = require('casual');
var password = casual.password.substring(10,{

    length: 10,
    uppercase: true,
    lowercase: true,
    number: true,
    symbols: true,
    strict: true
});

Creating your custom password generator is quite simple:

const getLowerCase = () => casual.random_element('ABCDEFGHIJKLMNOPQRSTUVWXYZ'.split(''));
const getUpperCase = () => casual.random_element('abcdefghijklmnopqrstuvwxyz'.split(''));
const getSpecialChar = () => casual.random_element('~!@#$%^*()_+'.split(''));
const getAnyCharacter = () => casual.random_element([getLowerCase(), getUpperCase(), getSpecialChar()]);

casual.define('customPassword', function() {
    const length = casual.integer(from = 7, to = 15);
    const password = [getLowerCase(), getUpperCase(), getSpecialChar()];
    
    while (password.length < length) {
       password.push(getAnyCharacter());
    } 
    return password.join('');
});

If security is a concern, remember to shuffle the password array before returning it.
