Oh, yeah. It’s still ongoing. You can track the progress at https://codeberg.org/rimu/pyfedi/src/branch/main/app/api/alpha/routes.py if you like. At the bottom of that page, things with a ‘Stage 1’ are what’s left to do.
The remaining stuff is mostly to do with chat / notifications. Once done, a basic app could be released, and then improved to include stuff that’s missing (things like uploading an image to post or a comment, and viewing reports)
EDIT: sorry, this was meant to be a reply to another comment. Still getting the hang of NodeBB. Now will this edit work …
