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

Usage

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

vardictionary=newTypo("en_US");

To use Typo in a standard web application you need to pass a settings object that provides a path to the folder containing the desired dictionary.

vardictionary=newTypo("en_US",false,false,{dictionaryPath: "typo/dictionaries"}),

If using in node.js, load it like so:

varTypo=require("typo-js");vardictionary=newTypo([...]);

or

importTypofrom"typo-js"vardictionary=newTypo("en_US",false,false,{dictionaryPath: "/node_modules/typo-js/dictionaries"})

Your path to node_modules may vary.

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

varis_spelled_correctly=dictionary.check("mispelled");

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

vararray_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

It also supports the Typo-specific flag PRIORITYSUGGEST. This allows you to specify that certain words should be given priority in the suggestions list when correcting a mispelled word. If you add the following to your .aff file (ideally on the line after NOSUGGEST):

PRIORITYSUGGEST @

and then add the @ flag to your new words in your .dic file, like

skibidi/@
rizz/@

then those words will be prioritized above other suggestions if they already appear in the suggestions list.

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.

Demo

There's a live demo of Typo.js at http://www.chrisfinke.com/files/typo-demo/ and a complete Node.js example file at examples/node/index.js.

Development

The full TypeScript source code and unit test suites are available in the official Typo.js repository at https://github.com/cfinke/Typo.js

To modify Typo.js, make your changes to ts/typo.ts and then run build.sh to generate the JavaScript file typo/typo.js.

IRL

Typo.js has been been used all over in real-world projects, but here are a few examples:

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.
Demo
There's a live demo of Typo.js at http://www.chrisfinke.com/files/typo-demo/ and a complete Node.js example file at examples/node/index.js.
Development
The full TypeScript source code and unit test suites are available in the official Typo.js repository at https://github.com/cfinke/Typo.js
To modify Typo.js, make your changes to ts/typo.ts and then run build.sh to generate the JavaScript file typo/typo.js.

Typo.js is a JavaScript/TypeScript spellchecker that uses Hunspell-style dictionaries.
Usage
To use Typo in a Chrome extension, simply include the typo.js file in your extension's background page, and then initialize the dictionary like so:
vardictionary=newTypo("en_US");
To use Typo in a standard web application you need to pass a settings object that provides a path to the folder containing the desired dictionary.
vardictionary=newTypo("en_US",false,false,{dictionaryPath: "typo/dictionaries"}),
If using in node.js, load it like so:
varTypo=require("typo-js");vardictionary=newTypo([...]);
or
importTypofrom"typo-js"vardictionary=newTypo("en_US",false,false,{dictionaryPath: "/node_modules/typo-js/dictionaries"})
Your path to node_modules may vary.
To check if a word is spelled correctly, do this:
varis_spelled_correctly=dictionary.check("mispelled");
To get suggested corrections for a misspelled word, do this:
vararray_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
It also supports the Typo-specific flag PRIORITYSUGGEST. This allows you to specify that certain words should be given priority in the suggestions list when correcting a mispelled word. If you add the following to your .aff file (ideally on the line after NOSUGGEST):
PRIORITYSUGGEST @

and then add the @ flag to your new words in your .dic file, like
skibidi/@
rizz/@

then those words will be prioritized above other suggestions if they already appear in the suggestions list.
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.
