A multitenant ActivityPub server for Ghost, built with Fedify. This service makes it possible for independent websites to publish their content directly to the Fediverse, enabling networked publishing to the open social web.

This repository is being actively developed and is currently in early alpha - expect many breaking changes. It is not suitable for production use.

We're publishing a weekly build-log about the development of this project. Sign up on https://activitypub.ghost.org

All requests to /.ghost/activitypub/*, /.well-known/webfinger and /.well-known/nodeinfo are proxied to this ActivityPub service using nginx. All other requests are forwarded to Ghost.

   • Use tailscale funnel 80 or ngrok http 80 to expose your local port 80
3. Configure Ghost
   • Run ghost config url and set it to the URL provided by Tailscale
4. Start the ActivityPub Service
   • Run yarn dev in the root directory of this project
5. Open Ghost Admin
   • Access your Ghost instance via the URL provided by Tailscale
6. Enable ActivityPub Alpha
   • Enable the ActivityPub Alpha flag in Settings → Labs

   • This will do the handshake between Ghost and ActivityPub to setup webhooks and Actor data

We use Biome for code formatting and linting.

If you use VS Code, you can install the Biome extension to get inline feedback.

To enable auto-formatting on save, you'll need to set the default formatter to Biome and enable Format on Save in your VS Code settings.

• Run yarn test to execute tests within a Docker Compose stack.

The below command will populate the DB with ~5000 followers for the activitypub host

• Run docker compose run scripts populate-activitypub-db

docker compose run migrate or docker compose run migrate-testing will run the up migrations against your dev or testing db respectively.

If you would like to run other commands you can run docker compose exec -it migrate /bin/bash or docker compose exec -it migrate-testing /bin/bash - This will drop you into a shell with the migrate binary available as well as a MYSQL_DB environment variable that is correctly formated for use as the -database argument to the migrate binary
