Bartender

Node.js bindings for the rustrict crate.

NOTE: rustrict was made by @finnbear, and not me! I am simply making bindings to it! Please check out his original project.

How capable is this library?

Since it's based off of rustrict, it has every capability of the rust crate! Here's what the original can do:

• Multiple types (profane, offensive, sexual, mean, spam)
• Multiple levels (mild, moderate, severe)
• Resistant to evasion
  • Alternative spellings (like "fck")
  • Repeated characters (like "craaaap")
  • Confusable characters (like 'ᑭ', '𝕡', and '🅿')
  • Spacing (like "c r_a-p")
  • Accents (like "pÓöp")
  • Bidirectional Unicode (related reading)
  • Self-censoring (like "f*ck")
  • Safe phrase list for known bad actors]
  • Censors invalid Unicode characters
  • Battle-tested in Mk48.io
• Resistant to false positives
  • One word (like "assassin")
  • Two words (like "push it")
• Flexible
  • Censor and/or analyze
  • Input &str or Iterator<Item = char>
  • Can track per-user state with context feature
  • Can add words with the customize feature
  • Accurately reports the width of Unicode via the width feature
  • Plenty of options
• Performant
  • O(n) analysis and censoring
  • No regex (uses custom trie)
  • 3 MB/s in release mode
  • 100 KB/s in debug mode

Limitations

This is handicapped by everything the original was:

• Mostly English/emoji
• Censoring removes most diacritics (accents)
• Does not detect right-to-left profanity while analyzing, so...
• Censoring forces Unicode to be left-to-right
• Doesn't understand context
• Not resistant to false positives affecting profanities added at runtime

How do I use this?

Simple! Just alias (or import) Bartender at the beginning of the your .js file to begin!

let bartender = require('@stalepretzels/bartender');   // commonjs require
import * as bartender from '@stalepretzels/bartender'; // esm import
// Simply remove `bartender.` from the beginning of the code if you plan on importing functions by themselves. 

Censor and check for profanity:

// censor(input: String) -> String
// is_inappropriate(input: String) -> bool

bartender.censor("hello crap") // -> "hello c***"

bartender.is_inappropriate("f u c k") // -> true

Type match strings:

// is(input: String, filter_input: String) -> bool
// isnt(input: String, filter_input: String) -> bool

bartender.is("pron", "evasive"); // -> true
bartender.isnt("porn", "evasive"); // -> true

bartender.is("Hello there!", "safe"); // -> true
bartender.is("nice work.", "safe"); // -> true
bartender.is("yes", "safe"); // -> true
bartender.is("NVM", "safe"); // -> true
bartender.is("gtg", "safe"); // -> true
bartender.isnt("not a common phrase", "safe"); // -> true

Roadmap

1. Add custom words and censors
2. Implement context feature
3. Array iterators
