url Universal Filter
Jump to heading
Works with the pathPrefix configuration option to properly normalize absolute paths in your content with the pathPrefix added. Useful if you host your site on GitHub Pages, which normally live in a subdirectory, e.g. https://11ty.github.io/eleventy-base-blog/. We set pathPrefix: "/eleventy-base-blog/" and our absolute links all have this prepended to the beginning.
If you don’t need pathPrefix (or don’t ever plan on moving your site’s top-level directory structure), you probably don’t need to use the url filter.
