fusc

Obfuscate and de-obfuscate text inside HTML elements. fusc transforms the text by replacing each non-whitespace character with another, and preserves the HTML structure by only mutating text nodes. Nested elements and inline elements with text will obfuscate just fine.

example

import fusc from 'fusc'
const text = document.querySelector('.text')

text.innerHTML // => '<p>hack the <a href="/planet">planet</a>!</p>'
fusc(text, { char: '@' })
text.innerHTML // => '<p>@@@@ @@@ <a href="/planet">@@@@@@</a>@</p>'
fusc(text)
text.innerHTML // => '<p>hack the <a href="/planet">planet</a>!</p>'

methods

fusc(element, [opts])

Obfuscate and de-obfuscate text within an element. First time fusc() is called it applies the transformation and the second time it's called it applies the reverse transformation and restores the original text.

element- a HTML element

The options can be:

opts.char - the replacement character. Replaces each character in the text. Defaults to *.

opts.transform - the transform function. Gets passed each character in the text and returns a character. Defaults to char => opts.char.

opts.timeout - a function returning the time in milliseconds waited before running the transformation on each text token. Gets passed in the iteration index of each token. Defaults to null which means no timeout.

install

With npm do:

npm install fusc
