Options

words: Record<string, ReadonlyArray<string>>

You can configure your Profane instance with a custom word list by supplying an object with word definitions:

const profane = new Profane({
  words: {
    happy: ['inappropriate'],
    awesome: ['elated'],
  },
});

profane.check('Mr. Happy is awesome'); // true
profane.getCategoryFrequencies('Mr. Happy is awesome'); // {inappropriate: 1, elated: 1}

You can receive a copy of the word list through the getWordList() function:

import { getWordList } from '@nkzw/profane';

getWordList(); // Record<string, ReadonlyArray<string>>
