First of all, I hope you understand my poor english skill.
I'm developing a server using socket.io and server contains all client's 'socket' variable that given as parameter to 'connection'. and I want to broadcast 'message' without all functions of 'io' object. so I plan to implement broadcast function like that.
let socketList = [ ... ]; // <-- that array contains socket of client.
for (let i = 0; i < socketList.length; ++i)
socketList[i].emit(...);
but It makes no sence to me. because I don't know that's same with io.emit function. so my question is: Is that code same with io.emit(...)?
That code and io.emit()
will do the same thing if all your clients really are in socketList
. If this is about performance and you don't have to do anything fancy like filtering out certain clients, I would go with io.emit()
, that way you won't need to keep your own socketList.
