Instructions

This bookmarklet shows a profile or a post on another Mastodon server in your server’s web app.

Installation

• Change the value of HOST to the domain of your Mastodon server.
• Create a bookmark and paste the lines in show-in-mastodon-web-app.js into its address (browsers are OK with pasting multiple lines).

Usage

• Go to a profile or a post on another Mastodon server.
• Click the bookmarklet.

If you are on your Mastodon server, the bookmarklet does nothing.

Acknowledgement: Thanks to @[email protected] for telling me the authorize_interaction trick.

      const userName = parts[1];
      location.href = `https://${HOST}/${userName}@${location.host}`;
