Websocket vs Long Polling for Phoenix what is the best choice?
The only answer that matters:
“It depends”
Seriously though, without more context it’s meaningless to recommend one over the other. There’s times long polling is appropriate, there’s times websockets are appropriate.
Typically with a Phoenix channel you’d be using websockets as the transportation layer, unless you have some requirements where websockets cannot be used.
Which will be supported by Phoenix in the future?
Websockets are better because they were designed for bi-directional communication. Longpolling is a hack and you should only use if it you cannot use websockets.
