Serving nodejs static files in the same domain as my wordpress

server { listen 80; listen [::]:80; server_name www.domain.com.br; return 301 http://www.domain.com.br$request_uri;

root /var/www/html;
index index.php index.html index.htm index.nginx-debian.html;
location / {
   #try_files $uri $uri/ =404;
   try_files $uri $uri/ /index.php$is_args$args;
}

location ~ \.php$ {
    include snippets/fastcgi-php.conf;
    fastcgi_pass unix:/run/php/php7.0-fpm.sock;
}

 location ~ /\.ht {
    deny all;
}

location = /favicon.ico { log_not_found off; access_log off; }
location = /robots.txt { log_not_found off; access_log off; allow all; }
location ~* \.(css|gif|ico|jpeg|jpg|js|png)$ {
   expires max;
   log_not_found off;
}

location /sistema/ { //RUNNING NODEJS RIGHT HERE
    proxy_read_timeout 600;
    client_max_body_size       500M;
    proxy_pass http://localhost:8080;
    proxy_set_header Host      $host;
    proxy_set_header X-Real-IP $remote_addr;

} }

I would like to serve my static files or my uploaded files from my NODEJS System through www.mydomain.com.br/sistema/uploads/path/tofile www.mydomain.com.br/sistema/views/path/to/views I am using express.static(__dirname + ‘/public’); as static folder;

Is there a possibility? I have been trying to set my server blocks, but I get 404 nginx using those url’s above.

Thank you,
