typo-js

What is typo-js?

The typo-js npm package is a JavaScript library for spell checking. It uses Hunspell dictionaries to provide spell checking functionalities, which makes it highly customizable and capable of supporting multiple languages.

What are typo-js's main functionalities?

Spell Checking

This feature allows you to check if a word is spelled correctly. In this example, the word 'example' is checked against the 'en_US' dictionary.

const Typo = require('typo-js');
const dictionary = new Typo('en_US');
const isCorrect = dictionary.check('example');
console.log(isCorrect); // true

Suggesting Corrections

This feature provides suggestions for misspelled words. In this example, the word 'exampel' is misspelled, and the dictionary suggests 'example', 'exemplar', and 'exemplary' as corrections.

const Typo = require('typo-js');
const dictionary = new Typo('en_US');
const suggestions = dictionary.suggest('exampel');
console.log(suggestions); // ['example', 'exemplar', 'exemplary']

Loading Custom Dictionaries

This feature allows you to load custom dictionaries from a specified path. In this example, the 'en_US' dictionary is loaded from a custom path.

const Typo = require('typo-js');
const dictionary = new Typo('en_US', false, false, { dictionaryPath: '/path/to/dictionaries' });
const isCorrect = dictionary.check('example');
console.log(isCorrect); // true

This dictionary is based on a subset of the original English wordlist created by Kevin Atkinson for Pspell and Aspell and thus is covered by his original LGPL license. The affix file is a heavily modified version of the original english.aff file which was released as part of Geoff Kuenning's Ispell and as such is covered by his BSD license.

Thanks to both authors for their wonderful work.
