Base path

Automatically add a base path to all urls


The base_path plugin fixes all URLs in your HTML documents by prepending the path of the location setting. It's useful if your site is hosted in a subdirectory.

It will search for any element with the attribute href, src, srcset and imagesrcset in your html pages and automatically fix the URLs. Note that the plugin only works with HTML pages, it won't fix CSS or JavaScript files.


Import this plugin in your _config.ts file to use it:

import lume from "lume/mod.ts";
import basePath from "lume/plugins/base_path.ts";

const site = lume();


export default site;


Let's say we have configured the location of the website to This means that all path URLs should be inside /blog/ directory.

import lume from "lume/mod.ts";
import basePath from "lume/plugins/base_path.ts";

const site = lume({
  location: new URL(""), // ← Note the path /blog/


This plugin will fix all absolute paths like this:

<a href="/articles/my-second-article/">Go to the second article</a>

Prepending the /blog/ prefix:

<a href="/blog/articles/my-second-article/">Go to the second article</a>
