List clients in a room?

[inca]

In 0.9.x we had a nice method .clients. Is there any equivalent in 1.0?

Can this be re-opened for version 4?

@ChristopherHButler you can use the fetchSockets() method, which has been added in Socket.IO v4.0.0:

// return all Socket instances
const sockets = await io.fetchSockets();

// return all Socket instances in the "room1" room of the main namespace
const sockets = await io.in("room1").fetchSockets();

// return all Socket instances in the "room1" room of the "admin" namespace
const sockets = await io.of("/admin").in("room1").fetchSockets();

// this also works with a single socket ID
const sockets = await io.in(theSocketId).fetchSockets();
