Answer 1

Socket.io use /socket.io after your domaine name. Then you have to specify the socket.io location :

location ~* \.io {
    proxy_pass http://localhost:8080;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection 'upgrade';
    proxy_set_header Host $host;
    proxy_cache_bypass $http_upgrade;        
}

And don't forget the upstream for your node js app

upstream app_yourdomain {
    server 127.0.0.1:3000;
    keepalive 8;
}
