Rehype URL Inspector

A rehype plugin to inspect, validate, or rewrite URLs anywhere in an HTML document

Features

Inspect every URL on an HTML page and do whatever you want to, such as:
- Normalize URLs
- Check for broken links
- Replace URLs with different URLs
- Add attributes (like target="blank") to certain links
Finds all types of URLs by default, such as:
- <a href="http://example.com">
- <img src="img/logo.png">
- <link rel="stylesheet" href="/css/main.css">
- <link rel="manifest" href="/site.manifest">
- <meta rel="canonical" content="https://example.com/some/page/">
- <meta property="og:image" content="img/logo.png">
- <script src="//example.com/script.js">
- <script type="application/ld+json">{"url": "www.example.com"}</script>
- <style>body { background: url("/img/background.png"); }</style>
You can remove the built-in URL rules
You can add your own custom URL rules
You can abort the URL search at any time

Example

example.html
This HTML file contains many different types of URLs:

1<html>
2  <head>
3    <link rel="canonical" href="http://example.com/some/page/">
4    <link rel="manifest" href="/site.webmanifest">
5    <link rel="icon" type="image/png" sizes="32x32" href="/img/favicon.png">
6    <link rel="stylesheet" type="text/css" href="/css/main.css?v=5">
7
8    <meta name="twitter:url" content="http://example.com/some/page/">
9    <meta name="twitter:image" content="http://example.com/img/logo.png">
10
11    <script type="application/ld+json">
12      {
13        "@context": "http://schema.org",
14        "headline": "Hello, World!",
15        "url": "http://example.com/some/page/",
16        "image": "http://example.com/img/logo.png"
17      }
18    </script>
19
20    <style>
21      body {
22        background: #ffffff url("img/background.png") center center no-repeat;
23      }
24    </style>
25  </head>
26  <body>
27    <h1>
28      <a href="/">
29        <img src="/img/logo.png"> Hello World
30      </a>
31    </h1>
32    <p>
33      <a href="//external.com" target="_blank">Lorem ipsum</a> dolor sit amet,
34      non dignissim dolor. Sed diam tellus, <a href="some-page.html">malesuada, dictum nulla</a>.
35    </p>
36
37    <script src="//external.com/script.js"></script>
38  </body>
39</html>

example.js
This script reads the example.html file above and finds all the URLs in it. The script uses unified, rehype-parse, rehype-stringify, and to-vfile.

1const unified = require("unified");
2const parse = require("rehype-parse");
3const inspectUrls = require("@jsdevtools/rehype-url-inspector");
4const stringify = require("rehype-stringify");
5const toVFile = require("to-vfile");
6
7async function example() {
8  // Create a Rehype processor with the inspectUrls plugin
9  const processor = unified()
10    .use(parse)
11    .use(inspectUrls, {
12      inspectEach({ url }) {
13        // Log each URL
14        console.log(url);
15      }
16    })
17    .use(stringify);
18
19  // Read the example HTML file
20  let file = await toVFile.read("example.html");
21
22  // Crawl the HTML file and find all the URLs
23  await processor.process(file);
24}
25
26example();

Running this script produces the following output:

http://example.com/some/page/
/site.webmanifest
/img/favicon.png
/css/main.css?v=5
http://example.com/some/page/
http://example.com/img/logo.png
http://schema.org
http://example.com/some/page/
http://example.com/img/logo.png
img/background.png
/
/img/logo.png
//external.com
some-page.html
//external.com/script.js

Installation

You can install Rehype URL Inspector via npm.

1npm install @jsdevtools/rehype-url-inspector

You'll probably want to install unified, rehype-parse, rehype-stringify, and to-vfile as well.

1npm install unified rehype-parse rehype-stringify to-vfile

Usage

Using the URL Inspector plugin requires an understanding of how to use Unified and Rehype. Here is an excelleng guide to learn the basics.

The URL Inspector plugin works just like any other Rehype plugin. Pass it to the .use() method with an options object.

1const unified = require("unified");
2const inspectUrls = require("@jsdevtools/rehype-url-inspector");
3
4// Use the Rehype URL Inspector plugin with custom options
5unified().use(inspectUrls, {
6  inspect(urls) { ... },      // This function is called once with ALL of the URLs
7  inspectEach(url) { ... },   // This function is called for each URL as it's found
8  selectors: [
9    "a[href]",                // Only search for links, not other types of URLs
10    "div[data-image]"         // CSS selectors for custom URL attributes
11  ]
12});

Options

Rehype URL Inspector supports the following options:

Option	Type	Default	Description
`selectors`	array of strings, objects, and/or functions	built-in selectors	Selectors indicate where to look for URLs in the document. Each selector can be a CSS attribute selector string, like `a[href]` or `img[src]`, or a function that accepts a HAST node and returns its URL(s). See `extractors.ts` for examples.
`keepDefaultSelectors`	boolean	`false`	Whether to keep the default selectors in addition to any custom ones.
`inspect`	function	no-op	A function that is called once and receives an array containing all the URLs in the document
`inspectEach`	function	no-op	A function that is called for each URL in the document as it's found. Return `false` to abort the search and skip the rest of the document.

URL Objects

The inspectEach() function receives a UrlMatch object. The inspect() function receves an array of UrlMatch objects. Each object has the following properties:

Property	Type	Description
`url`	string	The URL that was found
`propertyName`	string or undefined	The name of the HAST node property where the URL was found, such as `"src"` or `"href"`. If the URL was found in the text content of the node, then `propertyName` is `undefined`.
`node`	object	The HAST Element node where the URL was found. You can make changes to this node, such as re-writing the URL, adding additional attributes, etc.
`root`	object	The HAST Root node. This gives you access to the whole document if you need it.
`file`	object	The File object that gives you information about the HTML file itself, such as the path and file name.
