Noscrape - Node
Installation
To begin, install the noscrape library using npm:
$ npm install noscrape
New Instance
Create a new instance of the noscrape class by providing the path to your desired font file. This sets up noscrape to use the specified font for obfuscating text:
# with require
const { Noscrape } = require("noscrape");
# or import (ECMAScript Module)
import { Noscrape } from "noscrape";
const noscrape = new Noscrape("path/to/font.ttf");
Obfuscation
Obfuscate your text by calling the obfuscate method on your noscrape instance. This will convert your text into a series of unique characters from the Private Use Area (PUA) of Unicode, making it unreadable by standard means:
const obfuscatedText = noscrape.obfuscate("text to obfuscate");
console.log(obfuscatedText);
>
// one could also obfuscate an integer
obfuscatedInt = noscrape.obfuscate(1337);
// or an array
obfuscatedArray = noscrape.obfuscate({
test: "This is a Test",
another: {
test: "This is another Test",
}
});
Rendering
Render the obfuscated font into a Base64-encoded string using the render method. This encoded string can then be embedded directly into your HTML for easy use:
const b64Font = noscrape.render();
console.log(b64Font.toString("base64");

Putting it together
Combine everything into a complete HTML document. Embed the Base64-encoded font directly in your HTML using the @font-face rule and apply the obfuscated font to your text with CSS. This ensures that the obfuscated text is displayed correctly in the browser:
<html lang="en">
<head>
<title>Noscrape - DEMO</title>
<style>
@font-face {
font-family: 'noscrape-obfuscated';
src: url('data:font/truetype;charset=utf-8;base64,${font.toString("base64")}');
}
</style>
</head>
<body>
<div style="font-family: 'noscrape-obfuscated'">${obfuscated}</div>
</body>
</html>
