Some fun with PHP and MySQL Document Store
How to start:
$ sudo dnf install protobuf-devel
$ sudo pecl install mysql_xdevapi
$ echo "extension=mysql_xdevapi.so" > /etc/php.d/40-mysql_xdevapi.ini
You can use the PHP embedded server:
# php -S localhost:8000
In case you use it on localhost like explained above, in Firefox, you need to change the following confg (about:config) to false : security.csp.enable
