Laravel app wildcard Digitalocean nginx - laravel

Question

I have set up a Laravel app at Digitalocean (nginx).
It works fine when I go to site.com but when I go to www.site.com it won't load.
My question is how should I set up the DNS record at Digitalocean and how should i set the /etc/nginx/sites-available/default file:
www.site.com/path should redirect to site.com/path.
all the subdomain should refer to the main app site.
media.site.com should refer to other directory.
Thank you!
This is the file now:
server {
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;
root /var/www/hzofe/public;
index index.php index.html index.htm;
server_name localhost;
location / {
try_files $uri $uri/ /index.php?$query_string;
}
location ~ \.php$ {
try_files $uri /index.php =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}

Have you tries adding a cname record for DNS redirect?
Also, if you are using https you can make one cert for the alias domain and your regular with lets-encrypt.
