Does Room exist
Is there a way to determine if a room already exists without creating it (host) or joining it (client). For instance someone may already have created the room with the room code you are trying to use?
K----------------------
There isn’t an API in the provided docs to “peek” whether a room already exists on the server without going through the normal connect flow.
The architecture docs explicitly say that listing rooms / seeing who’s in them is something you currently have to manage yourself, not something the backend exposes directly.[Common questions] That implies there’s no official “room exists?” query separate from connecting.
From what’s documented:
Given the docs, the recommended approach is:

From what’s documented:
- Rooms are created on demand by the matcher when a client connects; the matcher checks if a room is already running in any cluster and spins one up if not.[Cloud architecture]
- The client-facing APIs (, ) are about connecting to a room, not checking for its existence.[Realtime class; Room class]
Given the docs, the recommended approach is:
K- Treat as idempotent: if the room already exists, you join it; if not, the backend creates it.
- If you need “room code already in use?” or “open lobby list” behavior, you must implement that yourself in your own backend or via persistent models inside Normcore (e.g., a “lobby index” model), but the details of such a pattern aren’t covered in the provided documents.

MOK, how would I get a list of rooms that already exist for a given App? I don't suppose I can do that. Yet if the room already exists I end up possibly joining someone else's session, surely that is undesirable? Or is there a simple way to set up a function to get the current list of rooms?
Mthe new quick match function will get you to the next available room but if you wanted a list of all rooms you'd still need unity lobby or something
MI believe we're going to ship an API for quickmatch to pull a list of rooms in the new year, but we're still working out the details there.
MGreat. That would be very useful for me. Thanks. In NormCore do we have to vote for features to highlight the desire for them?
