I will share my configuration to build ATOM and JSON feeds.
config-file:
disableKinds = ["RSS"] # kick out RSS
[mediaTypes]
[mediaTypes."application/atom+xml"]
suffixes = ["xml"]
[outputFormats.HTML]
baseName = "index"
NoUgly = true
[outputFormats.ATOM]
MediaType = "application/atom+xml"
BaseName = "feed"
suffix = "xml"
IsHTML = false
IsPlainText = false
noUgly = true
Rel = "alternate"
[outputFormats.JSON]
MediaType = "application/json"
BaseName = "feed"
suffix = "json"
IsHTML = false
IsPlainText = true
noUgly = false
Rel = "alternate"
[outputs]
home = [ "HTML", "ATOM", "JSON"]
section = [ "HTML", ]
page = [ "HTML" ]
taxonomy = [ "HTML" ]
taxonomyTerm = [ "HTML" ]
layout/_default/home.atom.xml Changed! Updated!
{{ print "<?xml version=\"1.0\" encoding=\"utf-8\" standalone=\"yes\" ?>"| safeHTML }}
{{ print "<?xml-stylesheet type=\"text/css\" href=\"/css/atom.css\" ?>"| safeHTML }}
{{ print "<!-- home.atom.xml -->"| safeHTML }}
<feed xmlns="http://www.w3.org/2005/Atom">

<subtitle type="text">Alle Beiträge der letzten 24 Monate</subtitle>
{{ with .OutputFormats.Get "ATOM" -}}

{{- end }}
<link rel="alternate" type="type/html" href="{{.Permalink}}" />

</entry>
{{- end }}
{{- end }}
</feed>
it uses page bundles to add an image to the feed. $start takes alle pages out of the last year. change it to range first .Param.RSSlimit for your need.
layout/index.json
{
"version": "https://jsonfeed.org/version/1",
"title": "{{ .Site.Title }}",
"home_page_url": "{{ .Site.BaseURL }}",
{{ with .OutputFormats.Get "JSON" -}}
"feed_url": "{{.Permalink}}",
{{- end }}
{{ if isset .Site.Params "description" -}}
"description": "{{ .Site.Params.description }}",
{{- end }}
{{ if isset .Site.Params "author" -}}
"author": { "name": "{{ .Site.Params.author }}" },
{{- end }}
"items": [{{ $start := now.AddDate -1 0 0}}
{{ range where .Site.Pages "PublishDate" "gt" $start -}}
{ {{ $page := .}}
"id": "{{ .Permalink }}",
"title": "{{ .Title | plainify}}",
"content_text": {{ .Summary | plainify | jsonify }},
"url": "{{ .Permalink }}",
"date_published": "{{ $page.PublishDate.UTC.Format .Site.Params.dateFormatFeed }}",
"date_modified" : "{{ $page.Lastmod.UTC.Format .Site.Params.dateFormatFeed }}",
"tags": ["{{ delimit .Params.tags ", " }}"]
},{{- end }}
{ }
]
}
works like the ATOM feed.
change it for your needs!
