quizlet-fetcher

Scraper for Quizlet sets (flashcards) to download them.

API

Node.js

Note: functionality to download cards was removed in 1.1.0. You'll need to provide the webpage yourself.

Note: As of now, you'll need to be authenticated to get all of the cards. This is because Quizlet will only provide the full set to authenticated users.

npm install quizlet-fetcher
# or
yarn add quizlet-fetcher

// ESM
import QuizletFetcher from "quizlet-fetcher"
// CJS
const QuizletFetcher = require("quizlet-fetcher").default

const quizlet = new QuizletFetcher(html) 

// Get the cards as JSON
// See below for format
quizlet.getJSON()

It's that simple. It should output something like this:

{
   "title":"Basic Japanese Phrases",
   "description":"Basic phrases from romaji to English",
   "author": "user123456",
   "cards":[
      {
         "term":"お げんき です か",
         "definition":"How are you?"
      },
      {
         "term":"わたし は げんき です, ありがとう",
         "definition":"I'm fine, thanks."
      },
      {
         "term":"さいきん どう です か",
         "definition":"What's new?"
      },
      {
         "term":"かわらない です",
         "definition":"Nothing much."
      },
      {
         "term":"すみません",
         "definition":"Excuse me",
         "image": "https://quizlet.com/cdn-cgi/image/f=auto,fit=cover,h=100,onerror=redirect,w=120/https://example.com/3826462.jpg",
         "sourceImage": "https://example.com/3826462.jpg"
      },
      {
         "term":"わたし と いっしょ に きて ください",
         "definition":"Come with me.",
         "image": "https://quizlet.com/cdn-cgi/image/f=auto,fit=cover,h=100,onerror=redirect,w=120/https://example.com/381937.jpg",
         "sourceImage": "https://example.com/381937.jpg"
      },
      {
         "term":"あなた は えいご/にほんご を はなします か",
         "definition":"Do you speak English/Japanese?",
         "image": "https://quizlet.com/cdn-cgi/image/f=auto,fit=cover,h=100,onerror=redirect,w=120/https://example.com/1767281.jpg",
         "sourceImage": "https://example.com/1767281.jpg"
      }
   ]
}

Note: the image field is a proxy image, usually from the CDN. sourceImage is the real image. You'll most likely want to use sourceImage

Browser

There is a folder named dist. It contains a browserified version of the parser. You can follow the above example, replacing require or import with window.QuizletFetcher.

You can compile it yourself using this command:

npm build

Example:

<script src="dist/index.min.iife.js"></script>
<script>
var html = document.body.innerHTML
console.log(window.QuizletFetcher(html)) // prints JSON, see example above
</script>
