Quick Tip: Minification of assets with Hugo

Posted by on . Last Updated on . Tagged:hugo

Today, I have been doing a general tidy up of my blog repository. One of the things that I decided to do, was reduce the overall amount of whitespace in the generated html files.

Reducing the overall amount of data that’s needed for an asset is called minification. Reducing the amount of data that’s required should not remove it where it will affect the rending of a webpage, eg: a preformatted code block. We minimise assets to improve the overall performance of downloading that asset. This can help improve page load speed for lower-bandwidth situations like mobile devices.

With hugo, you generate your site using the following command:


This outputs the static site on your behalf. To minify the HTML output, simply change the above command to:

hugo --minify

That’s it. The only thing that’s left to do is to publish your website.

Should you need it, Hugo also allows you to minify any CSS, JS, JSON, SVG or XML resource. To minify a resource, you need to pipe it to resources.Minify like this:

{{ $css := resources.Get "css/main.css" }}
{{ $style := $css | resources.Minify }}

Happy Hugo-ing!
