nginx config file

With assumption of node app running on port 6000

# Default server configuration
#
server {
	listen 80 default_server;
	listen [::]:80 default_server;

# if server domain is available for you. write next line as server_name example.com;
    #server_name example.com;
	server_name _;

	location /api {
		# First attempt to serve request as file, then
		# as directory, then fall back to displaying a 404.
		#try_files $uri $uri/ =404;
		proxy_pass http://127.0.0.1:6000;
