In 2015 I had started with CMS Joomla on a shared hosting. The easy way... Yeah, right... Easy Peasy.
And now I'm making projects with pure PHP(no CMS or PHP Frameworks), using Node.js based build system for frontend, prefer pure JavaScript on client side and LESS for styles. OSPanel as local server, HestiaCP on Cloud VPS from Hetzner with LAMP stack + NGINX as a reverse proxy for production websites with a self hosted email server. Not that it’s necessary, but if you start doing something, do it right!
Now I'm piping users through different trackers, sending conversion events to a bunch of analytics and advertising platforms, getting stats with API from dozens of services, and send push messages to separate users by this data... where's my Joomla...
I could write here a lot of names of living and dead services and technologies, active and not maintained code libs, frameworks and npm packages I've worked with, but I won't do that. There are really a lot of them.
