API

linkifyUrls(string, options?)

string

Type: string

A string with URLs to linkify.

options

Type: object

attributes

Type: object

HTML attributes to add to the link.

type

Type: string
Values: 'string' | 'dom'
Default: 'string'

The format of the generated content.

'string' will return it as a flat string like 'Visit <a href="https://example.com">https://example.com</a>'.

'dom' will return it as a DocumentFragment ready to be appended in a DOM safely, like DocumentFragment(TextNode('Visit '), HTMLAnchorElement('https://example.com')). This type only works in the browser.

value

Type: string | Function
Default: The URL

Set a custom HTML value for the link.

If it's a function, it will receive the URL as a string:

linkifyUrls('See https://sindresorhus.com/foo', {
	value: url => new URL(url).pathname
});
//=> 'See <a href="https://sindresorhus.com/foo">/foo</a>'

Browser compatibility

Version 3 of this package uses negative lookbehind regex syntax. Stay on version 2 if you need to support browsers that doesn't support this feature.
