Typo.js is a JavaScript spellchecker that uses Hunspell-style dictionaries. Its main use is to allow Chrome extensions to perform client-side spellchecking.

Usage

To use Typo, simply include the typo.js file in your extension's background page, and then initialize the dictionary like so:

var dictionary = new Typo("en_US");

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

Note: The manifest.json file in the root directory of the project is there to simplify testing, as it allows you to load all of the files in the Typo project as a Chrome extension. It doesn't have any purpose if you're using Typo.js in your own project.
