Miscellaneous settings.

Home Meta Description #

You can specify the homepage meta description with the following parameter:

[params]
description = "Your description"

Breadcrumbs #

Show breadcrumbs on pages.

Example:

[params.breadcrumbs]
enabled = true
showCurrentPage = true
home = "~"

Set enabled to false if you want to hide breadcrumbs. By default, breadcrumbs are shown.

Set showCurrentPage to false to hide the last crumb, i.e, the current page.

home when set with a non-empty string, uses the latter as the first crumb instead of the string “Home”.

Comments #

Enable comments on your posts using Giscus.

[params.giscus]
enable = false
repo = "your/repo"
repoid = "id"
category = "category"
categoryid = "categoryId"
mapping = "pathname"
theme = "preferred_color_scheme" 

Tip: use preferred_color_scheme theme to have a consistent dark and light appearance.

You can decide to hide the comments section on certain pages, using the following parameter on the page itself:

disableComment: true

Umami #

You can include Umami in your website as follows:

[params.umami]
enable = true
websiteId = "unique-website-id"
jsLocation = "http://example.org/umami.js"

Favicons #

The following favicons are included in the head of the website:

• favicon.ico
• favicon-16x16.png
• favicon-32x32.png
• android-chrome-192x192.png
• apple-touch-icon.png

You must override the existing one in your static folder.

You can also specify a subdirectory of /static if you prefer using the following param:

[params]
faviconPath = 'your-path'

You can easily generate favicons using this website starting from your image. Here you can see an example of icons overriding default ones.

OpenGraph #

Custom <code>og:image</code> (link preview images) #

Typo allows you to customize the image shown in the card generated by most social media apps (X/Bluesky/WhatsApp) when you share a link to your site. These apps follow the OpenGraph protocol and look for og:image meta tags in the markup of the links you share. Typo will render the og:image meta tag provided a suitable one can be found.

[!note] A size of 1200x630 is generally recommended for preview images.

A simple way to tell Hugo about the preferred image(s) to be used for og:image is by using the frontmatter images array with explicit paths to images. Otherwise, you can refer to Hugo docs on how the default template function looks for a suitable image. Typo respects and uses the image found in these aforementioned ways but otherwise, looks into the following cases.

To show the same preview image across all your pages not fitting the above conditions, copy the preview image to the location /assets/images/og-image.png. .webp and .jpg files are also supported. This image will usually be applied for links to the home page and other links without any explicitly specified images.

If you want more control, you can create your own layouts/partials/head/og-image.html in your Hugo project and provide custom templating to generate an image URL. Here’s an example that shows how an externally hosted service could be used for links other than the home page:

{{- if .IsHome -}}
  {{- with resources.GetMatch "images/og-image.{webp,png,jpg}" -}}
    {{- .RelPermalink -}}
  {{- end -}}
{{- else -}}
  {{- if .IsPage -}}
    {{- printf "/api/og-image?title=%s" (or .Title site.Title site.Params.title | urlquery) -}}
  {{- end -}}
{{- end -}}

Overriding og-image.html will still respect frontmatter/Hugo processing config and only applies if those scenarios fail.

Mermaid Diagrams #

Mermaid diagrams are supported, just follow this reference to use them. You can set Mermaid’s light- and dark themes in your config; they switch with your blog’s light/dark state. These are the defaults:

[params]
mermaidTheme = "default"
mermaidDarkTheme = "dark"
