Custom hugo RSS template
lastBuildDate
to show the page last modification time. Make a custom description
like adding image, use description
field instead of summary
or content
.Hugo ships with its own RSS 2.0 template, it generated the RSS feed file as index.xml
and embedded into index.html
header. e.g.
{{ range .AlternativeOutputFormats -}}
{{ printf `<link rel="%s" type="%s" href="%s" >` .Rel .MediaType.Type .Permalink | safeHTML }}
{{ end -}}
Generated html:
<link rel="alternate" type="application/rss+xml" href="https://djangocas.dev/blog/index.xml">
Default RSS template: https://github.com/gohugoio/hugo/blob/master/tpl/tplimpl/embedded/templates/_default/rss.xml
Add <lastBuildDate>
to <item>
show the page last modification time
By default, the individual <item>
only have <pubDate>
. I want to add <lastBuildDate>
as page’s last git commit. To do this. Change the RSS template file and use $.Page.Lastmod
as <lastBuildDate>
. e.g.
<lastBuildDate>{{ $.Page.Lastmod.Format "Mon, 02 Jan 2006 15:04:05 -0700" | safeHTML }}</lastBuildDate>
Change <description>
By default, <description>
is very simple, just use .Summary
:
<description>{{ .Summary | html }}</description>
To make more attractive, e.g. adding image in page, change .Summary
to use .Description
. Here is an example:
<description>
{{ $img := (.Resources.ByType "image").GetMatch "*featured*" }}
{{ with $img }}
{{ $img := .Resize "640x" }}
{{ printf "<![CDATA[<img src=\"%s\" width=\"%d\" height=\"%d\"/>]]>" $img.Permalink $img.Width $img.Height | safeHTML }}
{{ end }}
{{ .Description | html }}
</description>
The full <item>
for a reference:
<item>
<title>{{ .Section | title }}: {{ .Title }}</title>
<link>{{ .Permalink }}</link>
<lastBuildDate>{{ $.Page.Lastmod.Format "Mon, 02 Jan 2006 15:04:05 -0700" | safeHTML }}</lastBuildDate>
<pubDate>{{ .Date.Format "Mon, 02 Jan 2006 15:04:05 -0700" | safeHTML }}</pubDate>
{{ with .Site.Author.email }}<author>{{.}}{{ with $.Site.Author.name }} ({{.}}){{end}}</author>{{end}}
<guid>{{ .Permalink }}</guid>
<description>
{{ $img := (.Resources.ByType "image").GetMatch "*featured*" }}
{{ with $img }}
{{ $img := .Resize "640x" }}
{{ printf "<![CDATA[<img src=\"%s\" width=\"%d\" height=\"%d\"/>]]>" $img.Permalink $img.Width $img.Height | safeHTML }}
{{ end }}
{{ .Description | html }}
</description>
</item>
Enjoy.
