| // getDescription - given a url, this Eleventy filter extracts the meta | |
| // description from within the <head> element of a web page using the cheerio | |
| // library. | |
| // | |
| // The full html content of the page is fetched using the eleventy-fetch plugin. | |
| // If you have a lot of links from which you want to extract descriptions, the | |
| // initial build time will be slow. However, the plugin will cache the content | |
| // for a duration of your choosing (in this example, it's set to 1 day). | |
| // | |
| // The description is extracted from the <meta> element with the name attribute |
