[Nginx] Configuration for SPA

server {
    listen 0.0.0.0:80;
    listen [::]:80;
    default_type application/octet-stream;

    gzip                    on;
    gzip_comp_level         6;
    gzip_vary               on;
    gzip_min_length         1000;
    gzip_proxied            any;
    gzip_types              text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;
    gzip_buffers            16 8k;
    client_max_body_size    256M;

    root /usr/share/nginx/html;

    location / {
        try_files $uri $uri/ /index.html =404;
    }
}

The highlighted part is important, without this, if you hint the page url:

http://localhost:8080/orders/1

It will show 404 page, because it will be regareded as a server request.

With this line of code, it will return index.html, then Frontend framework can handle with the router.
