Flashcardz NPM

Flashcardz

Intelligently quizzes you

Features

Small typos are (pretty intelligently) ignored
You won't be quizzed too much over things you get right
You'll be quizzed a lot over things you get wrong
You won't see the same card over and over again (assuming you have enough cards); you'll get enough variety to learn
Importing stacks of cards from Quizlet works
Comes with a CLI that can help with basic things like removing duplicate cards or deleting your history of getting cards right/wrong
Comes with an API so that you can get quizzed from any interface (not just a terminal emulator)

Install

Assuming you have Node, installing the CLI is as easy as:

npm install -g flashcardz

To use Flashcardz programatically, use

npm install --save flashcardz

Usage

CLI

Say you have a file called myfile with flashcards (each card has a "front" and a "back" - normally, you see the front first and have to recall what the back is). Let's say myfile looks like this:

ostensible	stated or appearing to be true, but not necessarily so.
palpable	able to be touched or felt.
diaphanous	(especially of fabric) light, delicate, and translucent.

ProTip™: if you're studying stuff on Quizlet, you can just export your set of cards with the default settings to get a file like myfile in this example

Converting that file to a Flashcardz stack would look like this:

flash convert myfile tab/newline > mystack

The command above will convert myfile to a "stack" which would be saved as mystack which you can be quized on if you run:

flash quiz mystack

The CLI has many other commands. If you run flash help you can see a list of them and the arguments they take. You can also get help for individual commands with flash help [command], e.g. flash help convert

JS API

const f = require('flashcardz')

// Convert this nice-looking object with flashcards into the Flashcardz format
const myCards = f.convert({
  ostensible: 'stated or appearing to be true, but not necessarily so.',
  palpable: 'able to be touched or felt.',
  diaphanous: '(especially of fabric) light, delicate, and translucent.'
}, 'objecty')

// Get quized on the terminal over 1 card in that stack of flashcards
const myCardsAfterQuiz = flashcardz.quiz(myCards, require('flashcardz/cli-quizzer'), flashcardz.pick.random)

// Get the term that you struggled with most from quizzes
const hardestCard = flashcardz.hardest(myCardsAfterQuiz)
console.log(hardestCard.front + ' is a difficult word.') // ex: 'ostensible is a difficult word.'
