Sitemap support

Features

Sitemap support has been added. You can now give hyperlink your sitemap in XML, text, atom or rss format, or just supply it with your robots.txtif you use the Sitemap:-directives

Patches

• Fix #169: Wrong encoding of url-encoded characters when they are in a project root. See also Munter/netlify-plugin-checklinks#453
• Fix #188: Don't follow JavaScriptFetch relations

Bugfix release

Fix #182, related to the --pretty switch (#183)

Pretty URLs

Pretty URLs

Some web services let you link to a page without its .html extension. Hyperlink would fail when checking such links. A newly added --pretty boolean option enables support for these 'pretty' URLs.

Example:

<!-- /index.html -->
<a href="about">About</a>

<!-- /about.html -->
<h1>I am the about page</h1>

Name attributes as fragment identifiers

Although it's deprecated in HTML5 to use fragments to link to an elements name-attribute, the practice is still in wide use and browser also still support it.

The user interaction of clicking a link and having it work is more important than sticking to the word of the standard, so if browsers give a successful experience here, so should we.

Example:

<a href="#namefragment">goto</a>
<a name="namefragment">Welcome</a>

Check for redirects on fragment links

Pull requests

• #165 Emit an error if a relation with a fragment gets redirected (Andreas Lind, Peter Müller)

Github markdown fragments

Github markdown output where headings had slugified fragment links, but the corresponding id-attribute had a user-content- string prepended, which github then handles with javascript, are now retried by hyperlink to see if this special case is true.

example:

<a id="user-content-6-test262-status" class="anchor" aria-hidden="true" href="#6-test262-status">

Hyperlink will no longer report these fragments as broken if the content is hosted on github.com

ES Modules

New features

• Better ES6 support including module syntax
• Less noise when checking type compatibility of assets based on their incoming relations.

Maintenance

• Upgraded Assetgraph to v5.8.3

v4

Breaking changes

• Switch to Assetgraph 4
• Drop backwards compatibility for node < 8
• Renamed a bunch of test operator names
• Renamed a bunch of test names
• Deprecated --exclude CLI option (#113)

New features

• Added options.skipFilter to allow a user to avoid specific tests (#114)
• Added --skip CLI option to allow skipping specific tests from the command line (#114)
• Added options.todoFilter to allow a user to mark failed tests as todo (#115)
• Added --todo CLI option to allow mark failed tests as todo from the command line (#115)
• Check mismatching Content-Type headers (#138)
• Check missing Content-Type headers (#138)

Bugfixes

• Fixed memory leak (#106 #117 #121)
• Don't try to load <link rel=dns-prefetch href=...> urls via http(s) (#126)
• Escape newlines in html attributes that caused yaml blocks to become incompatible

Preconnect and timeout

Patches

• Don't attempt to load <link rel="preconnect"> as a link, but only establish a connection to check availability
• Set a default timeout of 30 seconds on all requests
• Use a user-agent that reveals this is hyperlink making the request

Canonical root and recursion

Breaking changes:

• The -r or --recursive option no longer recurses into source maps and source map sources. This lets you set recursion without getting errors for possibly unpublished source map sources

New features:

• A --source-mapoption has been added to enable you to fail on missing source maps or source map sources.
• A --canonicalroot option has been added. This allows hyperlink to resolve a canonical deployment URL as a local one. So https://mntr.dk/opengraph.jpg with a --canonicalroot https://mntr.dk/ would be resolved as /opengraph.jpg when your root is a local file system.

Fixes:

• Added more resilience against servers behaving weirdly when requesting with HEAD-method. A server would respond 502, and also respond 502 on an immediately attempt at recovering with a GET. Added yet another recovery retry on a timeout for this condition

Memory and Speed optimizations

Features:

• Added --debug option to show a memory usage increase from init to final run

Patches:

• Release memory by unloading assets with no outgoing relations. Fixes #117
• Switch external link checks to HEADrequests to reduce network load
• Fall back to GET requests for external requests when encountering known errors with HEADrequests
• Send better Accept-headers to reduce errors from external servers
