This package exposes lists of profane words in several languages. This rating does not represent how vulgar a term is. It represents how likely it is to be used as either profanity or clean text.

Use this for researching natural language. Don’t use it to make a “profanity filter”. Those are bad.

This package is ESM only. In Node.js (version 14.14+, 16.0+), install with npm:

npm install cuss

In Deno with esm.sh:

import {cuss} from 'https://esm.sh/cuss@2'

In browsers with esm.sh:

<script type="module">
  import {cuss} from 'https://esm.sh/cuss@2?bundle'
</script>

import {cuss} from 'cuss'
import {cuss as cussPt} from 'cuss/pt'

console.log(Object.keys(cuss).length) // 1776
console.log(Object.keys(cussPt).length) // 173

console.log(cuss.beaver) // 0
console.log(cuss.asshat) // 2

console.log(cussPt.burro) // 1
console.log(cussPt.bixa) // 2

cuss exports the following entries:

Map of offensive words to a sureness rating (Record<string, number>).

New terms can be added to the corresponding files as listed in the support section.

To add a new language, create a new JS file with a BCP 47 language tag as its name (lower case, dashes, and preferred and normalized).

After changing something, run npm install to install all required dependencies, then npm test to update: the project includes some scripts to make sure everything is in order. Note that the tests require Node.js 18.0+. Finally, open a pull request.

This package is safe.
