Benchmark

use oale8.mdx as an example:

Mdict#loading time: 0 sec
Mdict#lookup x 1,967 ops/sec ±0.95% (97 runs sampled)
Mdict#prefix x 1,800 ops/sec ±0.70% (96 runs sampled)
Mdict#fuzzy_search x 285 ops/sec ±14.03% (77 runs sampled)
Mdict#associate x 2,059 ops/sec ±4.53% (89 runs sampled)
Fastest is Mdict#associate

depreciate if you use js-mdict @2.0.3, you can use api shown below:

Note: 2.0.3 not supports mdd file, and record info encrypted file

import path from 'path';
import Mdict from 'js-mdict';

const dictPath = path.join(__dirname, '../resource/Collins.mdx');
const mdict = new Mdict(dictPath);
mdict
  .build()
  .then((_mdict) => {
    console.log('hello', _mdict.lookup('hello'));
    console.log('world', _mdict.lookup('world'));
    console.log(_mdict.attr());
  })
  .catch((err) => {
    console.error(err);
  });
