Profanity

A JavaScript profanity filter (with TypeScript support)

Getting Started

Install package

npm i @2toad/profanity

if you're using Node 11.x or older you'll need to install Profanity 1.x (e.g., npm i @2toad/[email protected])

Usage

import { profanity } from '@2toad/profanity';
// or
var profanity = require('@2toad/profanity').profanity;


profanity.exists('I like big butts and I cannot lie');
// true

profanity.exists('I like big glutes and I cannot lie');
// false

profanity.censor('I like big butts (aka arses) and I cannot lie');
// I like big @#$%&! (aka @#$%&!) and I cannot lie

profanity.censor('I like big butts (aka arses) and I cannot lie', CensorType.FirstChar);
// I like big *utts (aka *rses) and I cannot lie

Options

Create an instance of the Profanity class to change the default options:

import { Profanity, ProfanityOptions } from '@2toad/profanity';

const options = new ProfanityOptions();
options.wholeWord = false;
options.grawlix = '*****';
options.grawlixChar = '$';

const profanity = new Profanity(options);

wholeWord

By default this is set to true, so profanity only matches on whole words:

profanity.exists('Arsenic is poisonous but not profane');
// false

Setting this to false, results in partial word matches:

profanity.exists('Arsenic is poisonous but not profane');
// true (matched on arse)

grawlix

By default this is set to @#$%&!:

profanity.censor('I like big butts and I cannot lie');
// I like big @#$%&! and I cannot lie

Setting this to ****, results in:

profanity.censor('I like big butts and I cannot lie');
// I like big **** and I cannot lie

grawlixChar

When specifying a CensorType other than CensorType.Word, this is the character used by the censor function.

By default this is set to *:

profanity.censor('I like big butts and I cannot lie', CensorType.AllVowels);
// I like big b*tts and I cannot lie

Setting this to $, results in:

profanity.censor('I like big butts and I cannot lie', CensorType.AllVowels);
// I like big b$tts and I cannot lie

Customize the word list

Add words:

profanity.addWords(['aardvark', 'zebra']);

Remove words:

profanity.removeWords(['butt', 'arse']);

Whitelist

The whitelist allows you to specify words that are always ignored by the profanity filter.

This can be useful if you want to turn partial word matching on (wholeWord = true), so combined words are caught (e.g., arselicker), while specific words you add to the whitelist are ignored (e.g., arsenic).

Add words to the whitelist:

profanity.whitelist.addWords(['arsenic', 'buttress']);

Remove words from the whitelist:

profanity.whitelist.removeWords(['arsenic', 'buttress']);
