So I wrote a little web app that allows a user to move their user data, like settings and subscribed/banned communities, from one account/instance to another.

It runs completely client-side, but is hosted on GitHub for the moment. Maybe it’ll be of some use!

Features:

  • Don’t trust me or GitHub? Clone the project and host it yourself or run it locally (Example in Wiki)
  • Export user data from any Lemmy instance (>=v0.19)
  • Download user data as a text file
  • Modify user data, e.g. to add or remove followed users/communites (Example in Wiki)
    • “display_name” ​
    • “bio” ​
    • “avatar” ​
    • “banner” ​
    • “matrix_id” ​
    • “bot_account” ​
    • “settings” ​
    • “followed_communities” ​
    • “saved_posts” ​
    • “saved_comments” ​
    • “blocked_communities” ​
    • “blocked_users” ​
    • “blocked_instances”
  • Transfer user data to the target account on the target instance
  • warmaster@lemmy.world

    Could this work offline as a PWA? By offline I mean not hosted on your server, but locally.

      Sure, the code is completely client-side, simply clone it. If you’re running into CORS problems due to the file:// scheme Origin of opening a local file, simply host it as a local temporary server with something like python -m http.server .

      This is due to the two ways most instances validate Cross-Origin requests:


      • Sending Access-Control-Allow-Origin: * (allow all hosts)
      • Dynamically putting your Origin into the Origin header of the response to your requests by the backend

      file:// URLs will result in a null or file:// Origin which can’t be authorized via the second option, therefore the need to sometimes host the application via (local) webserver.
