nginx.conf

server {
  listen 80;
  root /usr/share/nginx/html;
  gzip on;
  gzip_types text/css application/javascript application/json image/svg+xml;
  gzip_comp_level 9;
  etag on;
  location / {
    try_files $uri $uri/ /index.html;
  }
  location /static/ {
    add_header Cache-Control max-age=31536000;
  }
  location /index.html {
    add_header Cache-Control no-cache;
  }
  location /config.json {
    add_header Cache-Control no-cache;
  }
}

here's the ideal one for https, just change your paths

server {
listen [::]:443 ssl ipv6only=on;
listen 443 ssl;
ssl_certificate /etc/ssl/certs/cert.crt;
ssl_certificate_key /etc/ssl/certs/cert.key;

root /var/www/example.com/public;
index index.html index.htm;

server_name example.com www.example.com;

if ($host = www.example.com) {
return 301 https://example.com$request_uri;
}
location / {
root /var/www/example.com/public/;
try_files $uri $uri/ /index.html =404;
}
}
server {
listen 80;
listen [::]:80;

if ($host = example.com) {
return 301 https://$host$request_uri;
}
if ($host = www.example.com) {
return 301 https://example.com$request_uri;
}
return 404;
}
