slugify
Universal Filter New in v1.0.0
Jump to heading
In versions prior to 1.0.0, the
slug
Universal Filter was used. To maintain backwards compatibility moving forward, slug
is still included and supported but slugify
is now recommended as best practice—it has better default behavior for URLs with special characters.Uses the @sindresorhus/slugify
npm package to convert a string into a URL slug. Typically used with permalinks.
Filename slugify.md
---
title: "My Title"
permalink: "/{{ title | slugify }}/"
---
Outputs to `/my-title/`.
Upgrade from slug
to slugify
Jump to heading
If you’re trying to migrate the content in a pre-1.0 project from using the slug
filter to the new slugify
filter (note: this is optional—you can leave them as-is!), you must take extra care to make sure that any existing URLs don’t change. The @11ty/eleventy-upgrade-help
plugin will compare the slug
and slugify
versions of your URLs to see if there are any that require extra attention (thank you to Peter deHaan for the assist here!).
