Features

  • Accuracy
    Linkify uses a (close to) complete list of valid top-level domains to ensure that only valid URLs and email addresses are matched.
  • Speed
    Each string is analyzed exactly once to detect every kind of linkable entity
  • Extensibility
    Linkify is designed to be fast and lightweight, but comes with a powerful plugin API that lets you detect even more information like #hashtags and @mentions.
  • Small footprint
    Linkify and its jQuery interface clock in at approximately 15KB minified (5KB gzipped) - approximately 50% the size of Twitter Text
  • Modern implementation
    Linkify is written in ECMAScript6 and compiles to ES5 for modern JavaScript runtimes.
    • Linkify is compatible with all modern browsers, as well as Internet Explorer 9 and up.

Quick Start

Add linkify and linkify-jquery to your HTML following jQuery:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script> <script src="linkify.min.js"></script> <script src="linkify-jquery.min.js"></script>

Note: A polyfill is required for Internet Explorer 8.

Find all links and convert them to anchor tags

$('p').linkify(); $('#sidebar').linkify({     target: "_blank" });

Find all links in the given string

linkify.find('Any links to github.com here? If not, contact [email protected]');

Returns the following array

[   {     type: 'url',     value: 'github.com',     href: 'http://github.com'   },   {     type: 'email',     value: '[email protected]',     href: 'mailto:[email protected]'   } ]

See all available options

Node.js/Browserify

var linkify = require('linkifyjs'); require('linkifyjs/plugins/hashtag')(linkify); // optional var linkifyHtml = require('linkifyjs/html');

Example string usage

linkifyHtml('The site github.com is #awesome.', {   defaultProtocol: 'https' });

Returns the following string

'The site <a href="https://github.com">github.com</a> is <a href="#awesome">#awesome</a>.'

AMD

<script src="r.js"></script> <script src="linkify.amd.js"></script> <script src="linkify-plugin-hashtag.amd.js"></script> <!-- optional --> <script src="linkify-element.amd.js"></script>
require(['linkify'], function (linkify) {   linkify.test('github.com'); // true   linkify.test('github.com', 'email'); // false });  require(['linkify-element'], function (linkifyElement) {    // Linkify the #sidebar element   linkifyElement(document.getElementById('sidebar'), {     className: 'my-link'   });    // Linkify all paragraph tags   document.getElementsByTagName('p').map(linkifyElement); }); 

Note that if you are using linkify-jquery.amd.js, a jquery module must be defined.

Browser globals

<script src="react.js"></script> <script src="react-dom.js"></script> <script src="linkify.js"></script> <script src="linkify-react.js"></script>
linkify.test('[email protected]'); // true  ReactDOM.render(   <Linkify options={{ignoreTags: ['style']}}>     Check out soapboxhq.com it is great!   </Linkify>,   document.getElementById('#container'); );

Browser Support

Linkify works on all modern browsers.

Linkify natively supports Internet Explorer 9 and above. Internet Explorer 8 is unofficially supported with a polyfill.

You can use either es5-shim (sham also required) or the provided linkify-polyfill.js:

<script src="jquery.js"></script>  <!--[if IE 8]> <script src="linkify-polyfill.js"></script> <![endif]--> <script src="linkify.js"></script> <script src="linkify-jquery.js"></script>

Node.js Support

Linkify is tested on Node.js 8 and up. Older versions are unofficially supported.

Caveats

The core linkify library (excluding plugins) attempts to find emails and URLs that match RFC specifications. However, it doesn't always get it right.

Here are a few of the known issues.

  • Non-standard email local parts delimited by " (quote characters)
    • Emails with quotes in the localpart are detected correctly, unless the quotes contain certain characters like @.
  • Slash characters in email addresses
  • Non-latin domains or TLDs are not supported (support may be added via plugin in the future)
