Apigility is a great tool for designing API’s
However I see no easy way to restart the server. Or at least they are not documenting it.
Anyways to do it. First navigate to the installation folder the run
php -S 0.0.0.0:8888 -t public public/index.php
The reason Apigility don’t provide instructions to start the server like this is because this starts out php test server.
You can launch the application anytime by serving out the application via your usual web server (nginx, apache, wamp etc).
Thank you Matthew for the correction.
