Manuel has created a brilliant service, using the most appropriate solutions, at the time.
As time has passed, technology has evolved, and the project needs to think about the best way to implement the service, in the future.
PHP and JsRender are currently used and work, but other frameworks are out there, such as Vue and React.
HamAlert would welcome your view on which technology should be used going forward, and if you have any ideas, or would like to help with the dev side of things, please comment, here.
Thanks,
Chris
