phrase-blacklist

Filter out strings with banned words and bypasses some evasion

Installing

Using NPM

npm i phrase-blacklist  

Example

Import

const phraseBlacklist = require('phrase-blacklist')

Check if text is clean

phraseBlacklist.isClean('fucc that hurts!!', <options object>) 
//Returns true if text is safe
//Returns a string, the detected bad word, if the text contains a banned phrase

options:

[note: each option runs default if not defined. will not trigger action if set false]

innerHTMLOnly : boolean //Strips HTML elements from the text //defaults to false

clearDuplicates : object //Removes duplicate characters from the text. Does a layered check using the converted text. //defaults to {fromEachWord: true}

translateMaskChars : boolean //Prevent filter evasion by translating characters to another (ex. @ = a) //defaults to true

Get potential original message from masked characters

phraseBlacklist.translateMaskChars('I n33d t0 $h1t!!') 
//Returns the potential original message

Clients may try to bypass a chat filter in place by using characters similar, yet different to the intential characters.

Remove repeat characters

phraseBlacklist.RemoveRepeatCharacters('heeeeeckkkkkkk youu!')
//Returns, 'heck you'

Strip HTML tags

 phraseBlacklist.ExtractInnerHTML('<p attribute="hello">world</p>')
 //Returns, 'world'

Add to blacklist

phraseBlacklist.BanPhrases('https://') 
//Adds 'https://' to the list of banned phrases
//isClean('https://website.com') would then return false
//The parameter can be a single string or an array of strings

Remove from blacklist

phraseBlacklist.UnbanPhrases('https://') 
//Removes 'https://' to the list of banned phrases (If so added)
//isClean('https://') would then return true
//The parameter can be a single string or an array of strings
