Usage

import { createMemorablePassword } from 'memorable-password-generator'
 
(async () => {
  const dictionary = ['single','dimensional','array','of','strings']
 
  let password = createMemorablePassword(dictionary)
  console.log(password) // single87STRINGS
 
})()

Dictionary

createMemorablePassword expects a single-dimensional array of strings as a dictionary, which allows you to compose that argument from any function, method, or API call that returns exactly that. Or, you can hard-code it—you do you.

Options

const options = {
    upperCase: 'alternate', // alternate (default), none, all, alternate, random
    pattern: 'wdw', // any combination of 'w' and 'd', representing words and digits, respectively
    maxWordLength: null, // Specifying an integer will filter the dictionary down to words whose length does not exceed this value
    maxNumber: 100 // This value is an upper bound on the numerals generated by 'd' pattern segments, and will indicate how many zeroes to left-pad on those numerals
}

Examples

Each example assumes the following dictionary:

const dictionary = ['one','two','buckle','my','shoe','three','four','shut','the','door','five','six','pick','up','sticks','seven','eight','lay','them','straight','nine','ten','start','again']
