Utility for detection, filtering and replacement / obscuration of forbidden words

The original list of swearwords used by default was taken from here.

Please note: This small utility module is written to prevent or monitor the use of certain words in your content without keeping context in account. An improper use may compromise the meaning of your content. Keep in account when using.

npm install profanity-util

Returns a list of forbidden words found in a string.

Arguments

• target_string - String to search
• forbidden_list (Optional) - Array containing forbidden terms

Example

var profanity = require('profanity-util');

console.log(profanity.check('Lorem ipsum foo bar poop test poop damn dolor sit..'));
// [ 'poop', 'poop', 'damn' ]

Purifies a string or strings contained in a given object or array from forbidden words.

If an object is given as target, this method will recursively loop through its values and purify every string.

By default forbidden swearwords will be obscured in this format: a***b, although setting replace option to true will activate replacement mode, which replaces each forbidden word with a random entry from a small list of inoffensive words (See DEFAULT_REPLACEMENTS in lib/profanity.js). This mode could be a fun and different approach to discourage and prevent swearing on your platform / app.

The .purify method will return an Array containing two values:

1. The purified String / Object / Array
2. An Array containing all swearwords obscured / replaced

Arguments

• target - Object, Array or String to purify
• options (Optional) - Purification options (Explained below)

Options

• forbiddenList - Array of forbidden terms to replace or obscure
• replacementsList - Array of replacement words (To pick randomly from)
• obscureSymbol - Symbol used to obscure words if obscured is set to true
• replace- If set to true it will replace forbidden words (E.g. a*****b) instead of obscuring them

Examples

Obscure mode (default)

var profanity = require('profanity-util');

console.log(profanity.purify('lorem ipsum foo damn bar poop'));
// [ 'lorem ipsum foo d**n bar p**p, [ 'damn', 'poop' ] ]

console.log(profanity.purify({
	foo: 'poop',
	bar: { nested: 'damn', arr: [ 'foo', 'poop' ] }
}));
// [ { foo: 'p**p', bar: { nested: 'd**n', arr: [ 'foo', 'p**p' ] } }, [ 'poop', 'damn', 'poop' ] ]

Obscure mode, custom options

var profanity = require('profanity-util');

console.log(profanity.purify('foo poop', { obscureSymbol: '$' }));
// [ 'foo p$$p', 'poop' ]

console.log(profanity.purify('foo poop', { forbiddenList: [ 'foo', 'bar' ] }));
// [ 'f*o poop', 'foo' ]

Replace mode ({ replace: true })

var profanity = require('profanity-util');

console.log(profanity-util.purify('lorem ipsum foo damn bar poop'));
// [ 'lorem ipsum foo gingerly bar rainbows', [ 'damn', 'poop' ] ]

console.log(profanity-util.purify({
	foo: 'poop',
	bar: { nested: 'damn', arr: [ 'foo', 'poop' ] }
}));
// [ { foo: 'kitten', bar: { nested: 'unicorn', arr: [ 'foo', 'puppy' ] } }, [ 'poop', 'damn', 'poop' ] ]
