mediawiki-rc-mastodon-bot

This small program continuously relays RecentChanges from a MediaWiki site to a Mastodon account. Each toot will contain up to 4 items with their screenshots. The following toot is an example:

Prerequisites

1. You need a MediaWiki site. It doesn't have to be owned by you, but you should be allowed to redistribute their page titles, permalinks, and their screenshots to public social media.

   Base URL will be used. Note that MediaWiki base URLs usually do not include paths like wiki/ and w/.

2. Create a Mastodon account. I recommend botsin.space, a Mastodon server specialized for bots, but you can use any other Mastodon server too, except automatical tooting is allowed according to the rules of your server.

3. Create a Mastodon application from Preferences → Development → New Application. It requires 3 access scopes:

   • read:statuses
   • write:media
   • write:statuses

   Application name and Redirect URI do not matter as they are unused.

   Your access key will be used.

4. Optionally, you may need a Browserless account, if you can't or don't want to run a headless web browser on your own node (e.g., Deno Deploy). Don't worry! Browserless offers some prepaid balance for free.

   API Key will be used.

Download

Official executable binaries for Linux, macOS, and Windows are available in the releases page.

Usage

Here's a command to run with minimum options:

mediawiki-rc-mastodon-bot \
  https://your-mediawiki-site.wiki/ \
  https://your-mastodon-server.social/ \
  --mastodon-access-token=YOUR_MASTODON_ACCESS_KEY \
  --limit=16

If you want to use Browserless instead of your local web browser for capturing screenshots, use --browser-ws-endpoint option:

mediawiki-rc-mastodon-bot \
  https://your-mediawiki-site.wiki/ \
  https://your-mastodon-server.social/ \
  -a YOUR_MASTODON_ACCESS_KEY -C -l 16 \
  --browser-ws-endpoint wss://chrome.browserless.io?token=BROWSERLESS_API_KEY

For further options, use -h/--help option.

Continuous operation

This program does not provide daemon mode or long-running mode, but checks recent changes only once for a invoke. For continous operation, automate periodical execution using cron or some shell scripting, e.g.:

while true; do
  mediawiki-rc-mastodon-bot \
    https://your-mediawiki-site.wiki/ \
    https://your-mastodon-server.social/ \
    --mastodon-access-token=YOUR_MASTODON_ACCESS_KEY \
    --continue
  sleep 1800 # Every 30 minutes
done

Note that -C/--continue option is used together. With this option, only RecentChanges after the last fetched change are published to Mastodon.

Build

As this program is written in TypeScript & Deno, you need Deno first.

You could run your own modified version from the local source tree using run.sh script. It's basically a drop-in-replacement of official executable binaries.

To build executable binaries, use build.sh script. Output files will be placed under dist/ directory. The directory will be created if not exists.
