Decouple (and Resync) Multiple Users

[ax3l]

By default, all clients to a trame application share the same state, synchronizing all GUI elements with everyone connected to a server.

This is awesome, but we encountered now a few situations where we have a pure "analysis" interface to simulation, experimental & AI/ML data/models where multiple users might connect to a deployed trame server and explore on their own.

Is there a simple way to

• A) fully decouple the state between different connected users and
• B) maybe even programmatically, e.g., through a GUI element, intentionally "make one's state private" and at a later point "resync to a global state", e.g., to share a specific GUI state with others (as in trame's default)?

I assume this would need tinkering with the server.state and might be simple for A), e.g., something like:

@server.client.on("connect")
def on_connect(client):
    client.state.value = 0  # private to this client

Is that sensible? Is there already a trame-defined way for this (e.g., an env var)?

Is a workflow like B) even possible? In B), on re-sync I would like to impose the state of the last re-synced client onto everyone connected.

Yes you can deploy you trame app using our docker bundle which aims to do that separation (multi-user mode) automatically for you.
Or you can use the trame.tools.serve utility.

In general, you are not suppose to share a trame process across users unless it is explicitly for collaboration.
