Shared data

Reuse the same data in multiple pages

In the previous step we have created two pages using the same layout, by setting the same layout variable in each. This can be fine for a few pages but what if you have tens, hundreds, or thousands of pages using the same layout? _data files to the rescue!

Create a _data file

In your project directory create a _data.yml file with the following content:

layout: layout.vto

This is a special file containing data accessible by all pages in the same directory or subdirectory. In this file we have defined the variable layout so all pages have this variable too. There's no need to repeat it in the front matter of all pages so we can remove it there.

layout: layout.vto


_data files (and _data folders) are a very powerful feature of Lume. See shared data documentation for more examples.
