To keep the database size down on my personal Mastodon instance I routinely delete everything older than a few days. This includes anything I bookmarked. The same is true for E’s instance. There’s no ready way to get those bookmarks out of Mastodon into something else. Unlike for public things where you can get an RSS feed from instances by adding .rss to a url, for the non-public bookmarks you need to use the API.
With some suggestions by my automaton junior coding assistant I quickly had a working API call to read the bookmarks (the url is yourinstance/api/v1/bookmarks, and you need to create an access token in your Mastodon instance under the developers menu heading).
Outputting those bookmarks as RSS is a straightforward way to make it accessible to various other applications. So I added code to make an RSS feed. And it works. The code is up on Github.
I’ve added the feed both to my regular feed reader (a self-hosted FreshRSS instance), and to the RSS plugin for Obsidian. The latter so that I can easily access the bookmarks in my notes. The former so that I can from within my feedreader send it to various websites I control as well as have a second route to my notes.
A quick and satisfying home cooked coding snack.
