Site Crawler

Unlighthouse comes with multiple methods for URL discovery in the form of crawling.

  1. Add the specified site from --site or config
  2. Manually providing URLs via the --urls flag or urls on the provider.
  3. sitemap - Reading sitemap.xml, if it exists
  4. crawler - Inspecting internal links
  5. Using provided static route definitions

Sitemap

When a sitemap is with a medium-sized threshold (50 URLS), it will disable the crawler.

Disabling scan

If you know your site doesn't have a sitemap, it may make sense to disable it.

export default {  scanner: {    // disable sitemap scanning    sitemap: false  }}

Crawler

When enabled, the crawler will inspect the HTML payload of a page and extract internal links. These internal links will be queued up and scanned if they haven't already been scanned.

Disable crawling

If you have many pages with many internal links, it may be a good idea to disable the crawling.

export default {  scanner: {    crawler: false  }}

Manually Providing URLs

While not recommended for most use cases, you may provide relative URLs within your configuration file, or use the --urls flag.

This will disable the crawler and sitemap scanning.

Can be provided statically.

export default {  urls: [    '/about',    '/other-page'  ],}

Or you can return a function or promise.

export default {  urls: async () => await getUrls()}

Specify explicit relative URLs as a comma-seperated list.

unlighthouse --site https://example.com --urls /about,/other-page
