Installation

... install 'anki-apkg-parser'

Usage

The library provides two classes Unpack and Deck

Anki decks are compressed archives, so we should unpack it first using Unpack class:

import { Unpack, Deck } from 'anki-apkg-parser';

const deckPath = './favorite-cards.apkg';
const outPath = './deck-folder';

try {
    const unpack = new Unpack();
    // pass the deck path and the output path for unpacking the deck
    await unpack.unpack(deckPath, outPath);
}
...

Which files will you see after unpacking the deck?

• 0, 1, 2 - files with number names are media files (images, audio, video)
• collection.anki2 - old version of anki database
• collection.anki21 - more modern version of database
• collection.anki21b - the latest databse version
• media - Associative list of media files. Their numbers and real names. (Protocol Buffer or json file)
• meta - Meta data (Protocol Buffer or json file)

Quick usage of Deck class:

import { Unpack, Deck } from 'anki-apkg-parser';

// create deck instance using path to unpacked deck
const outPath = './deck-folder';
const deck = new Deck(outPath);


try {
    // open the database
    const db = await deck.dbOpen();

    // fetch list of all notes
    await db.getNotes();

    // fetch colleciton raw
    await db.getCollection();


    /**
     * Anki deck contains sqlite databases
     * so when you call dbOpen(), you will recieve an instance of sqlite library
     * You are free to use any 'sqlite' api
     */

    // make an SQL request by native sqlite api
    await db.get('SELECT * FROM col');
}
...

Advanced usage

TODO: descripbe this part

import { Unpack, Deck } from 'anki-apkg-parser';

const outPath = './deck-folder';

try {
    const outPath = './deck-folder';
    const deck = new Deck(outPath);

    let db;

    // get cards from anki2 db file
    if (deck.anki2) db = await deck.anki2.open()
    db.get('SELECT * FROM cards')
}
