Websockets with socket.io on AWS Elastic Beanstalk

There is a significant disadvantage with the ditch-nginx approach. You will have to move https into node and also to your socket.io calls. It's much easier to manage https in the server configuration rather than in node.

If you don't need https I suggest dumping the proxy and just going directly to the node.

you could try to go through the trouble of configuring nginx, but if you are only using websockets, it would be easier to turn off all proxys and directly connect.

this is under your app environment in the elastic beanstalk dashboard. There's a drop down button on the right marked "Actions". Select "Edit/Load Configuration"
