Creating pages


As said in Page files, the output filename is generated using the original source file path:

posts/  =>  /posts/my-first-post/index.html

By default, the pages are saved as "pretty URLs", using directories for the path and a index.html file. So the final URL is /posts/my-fist-post/. To disable this behaviour, set the option prettyUrls to false in your _config.js file (see Configuration).

const site = lume({
  prettyUrls: false,
/posts/  =>  /posts/my-first-post.html

The url variable

The variable url defined in the page allows to customize the output file individually. For example:

title: My first post
url: /posts/welcome/

In this example, the url value will be used to generate the output file instead of the filename:

/posts/  =>  /posts/welcome/index.html

Note that defining manually the URL of a page will makes that prettyUrls option won't have any effect. For example:

# This outputs /posts/welcome/index.html
url: /posts/welcome/

# This outputs /posts/welcome (a file without extension)
url: /posts/welcome

# This outputs /posts/welcome.html
url: /posts/welcome.html

Relative URLs

If you only want to change the last part of the URL, you can use relative paths. For example:

title: My fist post
url: ./welcome/

In this example, the page will be saved using the directory path where the source file is saved but adding welcome in the last part of the URL.

/posts/  =>  /posts/welcome/index.html

Using ../welcome/ as URL will remove also the last directory.

/posts/  =>  /welcome/index.html

URLs as functions

The variable url accepts also a function that will be used to generate the final value. This function will receive the current page as the first argument.

For example, let's say that we want to generate automatically all URLs of our posts, using the title value. We can create a _data.js file in the /post/ directory, with the following code:

export function url(page) {
  return `./${}/`;

Now, all pages in the post directory share the same url function, that returns the title of the page as a relative URL, for example ./My first post/ (See Shared data).

Due the URL is relative, the current directory is appended automatically (it will be resolved to /post/My first post/). And due all output paths are slugified automatically, the final page will be /post/my-fist-post/.

Using functions as URLs gives a lot of flexibility to generate the URLs as you want.
