sharing IO object in multiple node instances

Question

I want to share rooms created by socket.io between two node instances, already using redis-store but unable to get io.sockets.in(ROOM_ID).emit(MESSAGE,DATA) on different node in

Answer 1

If i good understanding your problem. youre start point was this question You can probably access to A from B (host not redis). So in A you can push that's you need to emit on A:

LPUSH dataToEmit "{'room':'room-ABCD', 'data':''}" 

and on your A process you perform a BRPOP on dataToEmit and on the callback you can unjsonize and emit that you want

may be you could also dispatch to 1 key for 1 room . Don't forget that's you can use a specific data base number for this stuff

I Hope that's migth help you
