External Link Page Preview/Bookmark Shortcode Help

support

Hello,

I want to create a shortcode to display page previews of external links in my content.

This image is an example of what I hope to create - with the resources that I am looking at.

In the post (Create an Article Preview in Hugo | Developer for Life) JeremyLikeness uses this shortcode:

{{$page := .Site.GetPage (.Get 0)}}
<div class="container alert alert-secondary">
    <div><a href="{{$page.RelPermalink}}" alt="{{$page.Title}}">
        <strong>{{ $page.Title }}</strong>
    </a></div>
    <div class="float-left m-2">
    {{ if $page.Params.image }}
        {{ $original := print "images/" (path.Base $page.Params.image) }}
        {{ $originalImg := $page.Resources.GetMatch $original }}
        {{ if $originalImg }}
            {{ $thumbnailImg := $originalImg.Fit "200x100" }}
            {{ printf `<img src="%s" alt="%s">` 
                $thumbnailImg.RelPermalink $page.Title | safeHTML }}
        {{end}}
    {{end}}
    </div>
    <p><small>{{$page.Description}}</small></p>
    <div class="clearfix"></div>
</div>

I want to create similar functionality with external sites.

Is it possible to create a shortcode that can access the metadata and preview images of other sites then saves this as some data to prevent future requests?

For sites that provide OG data, this approach might work:
