Having recently created an archive of my Mastodon posts…

…these are now also part of this website. The archive isn’t yet linked in the menu; it can be accessed at /mastodon.

Implementation

The implementation is quite straightforward using a Hugo Content Adapter. This reads the archive created in the previous post (as JSON) and generates representations in Hugo’s internal page format. To do this, an empty subdirectory with a file named _content.gotmpl must be created in the Hugo content directory. The example uses the name mastodon/_content.gotmpl for this.

At the start of the file, you simply need to specify the source file ($mastodonFile) and the folder where the media is stored ($mastodonMediaPath).

{{- $mastodonMediaPath := "mastodon/media/" -}}
