Lemmy Userdata Migration

cross-posted from: https://slrpnk.net/post/10823519

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:

  • Export user data from any Lemmy instance (>=v0.19)
  • Download user data as a text file
  • Modify user data in the browser, e.g. to add or remove followed instances
  • Transfer user data to the target account on the target instance
  • Emotet@slrpnk.netOPEnglish

    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.
