Update data on file change #10
Description
Since the data is loaded manually, and since we deactivated expensive file hashes, there is likely no notification when the file changes.
Since this uses a server extension, we can add another special route to listen for file changes and reset the DataModel.
Project like watchfiles can help to efficiently detect/listen for changes.
On the client-side a websocket connection or polling on this route will let the frontend know when to update.
