How it works

The user passes the contact link as an email, tel, sms, facetime, or href prop. The component obfuscates href data until a hover, click, or focus event. Links are given their proper URL schemes (mailto, facetime, etc.) The link is rendered in reverse in the dom, but reversed again with css. This making the link useless for spammers, but user friendly on screen.


The world needs obfuscated links that display the link in a friendly way.


npm install --save react-obfuscate


import React from 'react';
import Obfuscate from 'react-obfuscate';

export default () => (
    Phone: <Obfuscate tel="205-454-1234" />
    <br />
    Email:{' '}
        cc: '',
        bcc: '',
        subject: 'react-obfuscate',
        body: 'Down with the machines!',


Robot Interaction

  <a href="obfuscated" style="direction: rtl; unicode-bidi: bidi-override;"
  ><br />
  <a href="obfuscated" style="direction: rtl; unicode-bidi: bidi-override;"

Human Interaction

  Phone: <a href="tel:205-454-1234">205-454-1234</a><br>
  Email: <a href=";;subject=react-obfuscate&amp;body=Down%20with%20the%20machines!"></a>

Common Options

Prop Type Default Description
email string null email address of the intended recipient
headers object null subject, cc, bcc, body, etc
tel string null telephone number of the intended recipient
sms string null sms number of the intended recipient
facetime string null facetime address of the intended recipient
href string null Obfuscate any other URL type (e.g. WhatsApp)

Uncommon Options

Prop Type Default Description
linkText string 'obfuscated' add custom pre-interaction href attribute placeholder text
obfuscate boolean true set to false to disable obfuscation
obfuscateChildren boolean true set to false to disable obfuscation of children
element string 'a' use if you want to override the default a tag
onClick function null called prior to setting location (e.g. for analytics tracking)


npm start

Consecutive Obfuscate/inline elements

react-obfuscate is an inline element. Using consecutive inline elements inside a block element causes an issue with the bidi-override reversal on Chrome. To prevent this, add any text between the elements, wrap <Obfuscate/> with another element (like <span>), or add style={{display:'inline-block'}} to prevent any issues.

Example Case:

  <Obfuscate style={{ display: 'inline-block' }} email="" />
  <br />
  <Obfuscate style={{ display: 'inline-block' }} tel="+69 111 222 333" />

Obfuscating custom elements with the element prop

With the element prop, users can obfuscate any element, like paragraphs or headers. Changing the dom element also removes the href and onClick props. Custom styling is required due to handling of right-to-left direction styles. Usually, adding style={{textAlign:'left'}} will suffice.

Example Case:

<Obfuscate element="p" style={{ textAlign: 'left' }}>
  This paragraph is more secret than others.


By default, objects are not reversed in the dom, but other types are. The obfuscateChildren prop set will disabled this functionality when set to false. If the child is an object, like html elements are, it will be rendered normally.

Example Use Case
<Obfuscate email="" aria-label="Email Me">
  <svg width={24} height={21}>
      d="M12 12.713L.0 3h23.97L12 12.713zm0 2.574L0 5.562V21h24V5"
