A simple single-user ActivityPub server that should be somewhat compatible with Mastodon, developed on top of sinatree.
This is a work in progress. It currently supports the following things:
- SQLite backend
- Simple queue daemon for making HTTP requests out-of-band
- Web display and pagination of local notes
- Importing of Twitter API JSON output
- Following remote users, responding to follow requests, broadcasting of new note creation
- Processing of foreign note creation, undos, forwards, etc.
- Local caching of remote avatars and image attachments
- HTTP request signing and verification of incoming signed requests (works with strict servers like GoToSocial)
- Enough of the Mastodon API implemented to have basic functionality with 3rd
party clients like Metatext including web-based OAuth flow, image
uploading/attaching; though many clients other than Metatext do not support
API endpoints at subdirectories (
/notes/api/v1/...instead of/api/v1/...)
It does not support the following things:
- Inline RsaSignature2017 verification (see this and this)
- Tags
- Custom emoji
- Polls
- Web-based note creation
- Queue-based inbox
- Many of Mastodon's less-critical API endpoints like advanced searching, notifications, messages, bookmarks
Clone notes:
$ git clone https://github.com/jcs/notes.git
Then install Bundler dependencies:
$ bundle install --path vendor/bundle
Initialize a session secret key:
$ ruby -e 'require "securerandom"; print SecureRandom.hex(64)' > config/session_secret
Create a new database:
$ env RACK_ENV=production bundle exec rake db:migrate
Create the single user:
$ env RACK_ENV=production bin/console
> u = User.new
> u.username = "me"
> u.password = u.password_confirmation = "OrpheanBeholderScryDoubt"
> u.save
=> true
> u.contact.about = "Hello!"
> u.contact.realname = "Fred"
> u.contact.avatar_attachment = Attachment.build_from_url("https://example.com/images/my-avatar.jpg")
> u.contact.avatar_attachment.save
> u.contact.save!
=> true
