@noscrape/noscrape

this projects goal is to prevent anyone to scrape content from your html output

example-code

live demo

IMPORTANT NOTE

Bots are not able to process obfuscated text or it comes to unpredictable analytics results etc.
So please beware of using this technology on relevant content for indexed pages!

Example

// server-side obfuscation
const object = { title: "noscrape", text: "obfuscation" }
const { font, value }  = obfuscate(object, 'path/to/your/font.ttf')

⬇⬇⬇⬇ provide data ⬇⬇⬇⬇

// font will be provided as buffer
const b64 = font.toString(`base64`)

<!-- client-side visualization-->


<style> 
    @font-face {        
        font-family: 'noscrape-obfuscated';        
        src: url('data:font/truetype;charset=utf-8;base64,${b64}');    
    }
</style>

...

<span style="font-family: noscrape-obfuscated">
    <div>{ value.title }</div>
    <div>{ value.text }</div>
</span>    

Options

strength

 * obfuscation strength multiplier ( default: 1 )
 * all under 0.1 makes no sense ( paths can be simply back calculated )
 * all over 10 makes no sense ( looks like 💩 )
