Typo.js is a JavaScript spellchecker that uses Hunspell-style dictionaries.

To use Typo, simply load it like so:

var Typo = require("typo-js");
var dictionary = new Typo(lang_code);

Typo includes by default a dictionary for the en_US lang_code.

To check if a word is spelled correctly, do this:

var is_spelled_correctly = dictionary.check("mispelled");

To get suggested corrections for a misspelled word, do this:

var array_of_suggestions = dictionary.suggest("mispeling");

// array_of_suggestions == ["misspelling", "dispelling", "misdealing", "misfiling", "misruling"]

Typo.js has full support for the following Hunspell affix flags:

• PFX
• SFX
• REP
• FLAG
• COMPOUNDMIN
• COMPOUNDRULE
• ONLYINCOMPOUND
• KEEPCASE
• NOSUGGEST
• NEEDAFFIX
