Futility

Futility is a library for the client or server that can help you detect naughty words in strings. Users can usually find a way around word blacklists and censorship is an almost impossilbe task, but if you have to do it, Futility can help (maybe). By providing a word list and an object that represents alternatives to letters in those words, Futility will build a RegExp object that you can use to test your user's input.

Getting Started

Install

npm install futility

Import

import Futility from 'futility';

or require

const Futility = require('futility').default;

Basic Usage

// Create a futility object with the default provided words and lists
let futility = new Futility(/* customWordList, customLetterList */);
 
futility.test('Kiss my @$5') // returns true
 
futility.replace('Kiss my @$5', 'face') // returns 'Kiss my face'
 
futility.censor('Kiss my @$5' /*, customSymbols */) // returns 'Kiss my *!#'
 
// Create a futility object with a custom word list
let futility = new Futility([
    'boat',
    'car',
    'train'
]);
 
futility.test('I drive a car') // returns true

API

new Futility(/* customWordList, customLetterList */)

Creates a new instance of Futility with a custom word list and/or a custom letter list. If you do not provided your own lists the defaults will be used. You can take a look at the default word list and the default letter list to see how those are formatted.

.test(String s)

Returns true if a naughty word is found in string s and false if the string is clean.

.replace(String s, (String replacement|Function replacement))

Replaces naughty words in string s with string replacement or applys the replacement function to the matched string (same as String.replace).

.censor(String s /*, String [customSymbols='#$@&%*!'] */)

Will replace naughty words in string s with random characters, comic book style, from the default customSymbols or provided string of custom symbols.
