Node.js Profanity Utility

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

The original lists of swearwords used by default were taken from here and 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.

Install

npm install profanity-util

API

profanity.check(target_string, [languages], [ forbidden_list ])

#####async version is also available: profanity.checkAsync(target_string, [languages], [ forbidden_list ])

Returns a list of forbidden words found in a string.

Arguments

• target_string - String to search
• languages (Optional )- Array of languages to check words from. Accepts a string if just one language is needed.
• 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' ]

Or the async method:

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

profanity.checkAsync('Lorem ipsum foo bar poop test poop damn dolor sit..')
  .then(function (result) {
    console.log(result);
    // [ 'poop', 'poop', 'damn' ]
  })
  .catch(function (err) {
    console.log('Something went wrong.');
  });

profanity.purify(target, [ options ])

#####async version is also available: profanity.purifyAsync(target, [ options ])

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
• languages - Array of languages to check words from. Accepts a string if just one language is needed.
• 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
• maxRecursionDepth - If you are passing objects, a recursive iteration will be performed to fiind all strings inside it. You can set the maximum depth of the recursion.

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' ] ]

Async version:

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

profanity.purify('lorem ipsum foo damn bar poop')
  .then(function (result) {
    console.log(result);
    // [ 'lorem ipsum foo d**n bar p**p, [ 'damn', 'poop' ] ]
  })
  .catch(function (err) {
    console.log('Something went wrong.');
  });

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' ] ]
