Detect invalid and inefficient links on your webpages. Works with local files or websites, on the command line and as a node library.
Because web performance is not only about making your own page run smoothly, but also about giving people a quick navigation out of your page.

Hyperlink is known to:
$ npm install -g hyperlink
Hyperlink exposes an executable
hyperlinkin your npm binaries folder.
Command line usage and options:
Options: -h, --help Show this help [default: false] --root Path to your web root (will be deduced from your input files if not specified) --canonicalroot URI root where the project being built will be deployed. Canonical URLs in local sources will be resolved to local URLs --verbose, -v Log all added assets and relations. VERY verbose. --recursive, -r Crawl all HTML-pages linked with relative and root relative links. This stays inside your domain. --internal, -i Only check links to assets within your own web root
--pretty, -p Resolve "pretty" urls without .html extension to the .html file on disk [default: false] --source-maps Verify the correctness of links to source map files and sources. [default: false] --skip Avoid running a test where the report matches the given pattern --todo Mark a failed tests as todo where the report matches the given pattern --concurrency, -c The maximum number of assets that can be loading at once [default: 25]
Hyperlink takes any number of input files or urls. It is recommended having these urls on the same domain or be part of the same web site.
--rootoption is only needed for resolving root relative urls in case you are not sending in pages located in the web root.
hyperlink path/to/index.html --canonicalroot https://deployed.website.com/ -r --internal path/to/index.htmlwill recursively explore the internals links of your website to ensure internal integrity. It is recommended to make this a part of your build pipeline and block on errors, since any error is very likely to be actually user facing if our page is deployed.
hyperlink path/to/index.html --canonicalroot https://deployed.website.com/ -r path/to/index.htmlwill recursively explore all links of your website, internal and external, to ensure that you aren't linking to external resources that have been removed or are otherwiser failing. It is not recommended to block your build pipeline on a failure of external links, since they are out of your control. Run in this mode in a non-blocking way and fix the errors in the report at your leisure. It is recommended to to this regularly, since external assets can move or disappear without warning.
Hyperlink is using the TAP output format, which is sort of human readable, and very machine readable. Use the TAP output in your CI setup, or pipe the output through one of these awesome reporters to get improved human readability or an output Jenkins likes
These reporters are known to work well with hyperlink:
$ hyperlink https://mntr.dk/ | tap-spot
Tee is a very useful program when you want to save and replay TAP outputs. In order to save the output to a file but still see the logs on stdout you might run a command line like so:
hyperlink https://mntr.dk -r | tee mntr.dk.tap | tap-spot
