@cantoo/node-languagetool

This is a Node.js binding to the LanguageTool (LT) spellchecker. It is based on a local instance of LT. As it is a Java based framework, this binding will use node-jre, which provides an embedded local Java Runtime Engine.

Install

npm i @cantoo/node-languagetool

Usage

The following code

const lt = require('@cantoo/node-languagetool')

lt.check('This is wong. Tolt you so.', 'en-US').then(console.log)

should print something like this:
