Update SPA code in nginx conf?

[cowboy]

These snippets aren't necessary, but might be nice to add.

Serve static assets:

  # Serve static assets in /assets/ as-requested.
  location /assets/ {
    try_files $uri =404;
  }

Remove trailing slashes from app URLs:

  location / {
    # Remove trailing slashes.
    rewrite ^(/.*)/$ $1 permanent;
    try_files $uri /index.html;
  }
