I am having a nodejs running on port 8000 and nginx on port 80 on same server.

I want Nginx to handle all the requests(image,css,etc) and forward js requests to nodejs server on port 8000.

Is it possible to achieve this. i have configured nginx as reverse proxy but its forwarding every request to nodejs but i want nginx to process all except js.

nginx/sites-enabled/default/

upstream nodejs  {
  server localhost:8000; #nodejs

}

location / {
 proxy_pass  http://192.168.2.21:8000;
 proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
 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;
}
