Go chat

A very simple chat program using go-socket.io (from googollee) and martini (from codegansta).

Uses either a port or a socket.

After installing dependencies with: go get github.com/codegangsta/martini go get github.com/codegangsta/martini-contrib/render go get github.com/googollee/go-socket.io

Run with: go run chat.go

Reads PORT from environment, but uses a socket if SOCKET environment variable exists. Default port is 3000.

Example nginx.conf (a little changed from a live config):

upstream chat_server {
    # server 0.0.0.0:3000 fail_timeout=0;
    server unix:/webapps/chat/run/chat.sock fail_timeout=0;
}

server {
    listen 80;

    location /socket.io {
        proxy_pass http://chat_server;
        proxy_redirect off;
        proxy_buffering off;

        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
    }


    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto https;

        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_pass http://chat_server;
    }
}
