A Node.JS library that helps you convert any dictionary from EDRDG, transform their entries into more user-friendly schemas and create Anki notes from them.

import fs from 'fs';
import { convertJMdict, generateAnkiNotesFile, getWord } from 'henkan';
//const fs = require('fs');
//const { convertJMdict, generateAnkiNotesFile, getWord } = require('henkan');

const dictPath = './JMdict_e';
const dictContent = fs.readFileSync(dictPath, 'utf-8');

const dictWords = convertJMdict(dictContent);

const jmDict = undefined, id = undefined, kanjiDic = undefined, tanakaCorpus = undefined;

const noteTypeName = 'Word';
const deckName = 'Japanese::Vocabulary::No kanji form words';

const noKanjiFormWords = dictWords
    .filter(word => word.kanjiForms === undefined)
    .map(word => getWord(jmDict, id, kanjiDic, tanakaCorpus, word, noteTypeName, deckName));

const ankiNotesFile = generateAnkiNotesFile(noKanjiFormWords);

if (ankiNotesFile) fs.writeFileSync('./nokfwords.json', ankiNotesFile, 'utf-8');
