Clone the demo project:
$ git clone git@github.com:marcop73/expressive.git
After cloning is completed jump into the directory and install vendor libraries:
$ cd expressive && composer install
Run the php build in server:
$ composer run --timeout=0 serve
You can then browse to http://localhost:8080.
On PHP versions prior to 7.1.14 and 7.2.2, this command might not work as expected due to a bug in PHP that only affects linux environments. In such scenarios, you will need to start the built-in web server yourself, using the following command:
$ php -S 0.0.0.0:8080 -t public/ public/index.php
