Minidon

Minimal implementation of ActivityPub with Cloudflare Workers and D1.

What can we do?

• Having only one actor
• The actor is discovered via webfinger (so you can find the account from other instances)
• Notifying followers of new posts (so new posts show up in their timeline)
• Web interface to post messages

Screencast

Requirements

• Node.js
• Cloudflare Account

Installation

yarn install

Configuration

cp wrangler.sample.toml wrangler.toml

Fill the values:

• preferredUsername - Your account name. eg. yusukebe
• name - Your long name. eg. Yusuke Wada
• BASIC_USERNAME - Basic auth username for login to Web UI
• BASIC_PASSWORD - Basic auth password

Pick up the value of PRIVATE_KEY from the files generated by ssh-keygen:

ssh-keygen -b 4096 -m PKCS8 -t rsa -N '' -f id_rsa

You can also use the value as "Secret variables" in Cloudflare Workers.

Setup D1

wrangler d1 create minidon

database_id will be shown on your console. Copy it and paste into the value of database_id and preview_database_id in wrangler.toml.

Create tables:

wrangler d1 execute minidon --file minidon.sql

Development

yarn dev

Deploy

yarn deploy

Usage

@{name}@{minion.username.workers.dev} will be your account id. Paste it on such a Mastodon URL input, the account will be shown.

To post the message, access https://minion.username.workers.dev/ui.
