I use CodeIgniter (of course), Bootstrap, Smarty, jQuery, and I load everything I can from a CDN (jsDelivr). I use MySQL when needed, but I really love SQLite, especially for the FTS fulltext searching capabilities. I have written many classes to speed up the development of Forms, Hierarchies, Geolocation, CURLing, etc. I use the AdminLTE thanks to a previous recommendation from ivantcholakov, and I discovered the delights of the Ace Editor from a friend of mine in Alaska. LESS CSS and Parsedown is great. For ecommerce I would of recommended (until their price hike) Snipcart. I was almost going to use them. It is a great idea anyways. I think these questions are very useful. It's taken me 10 years to discover on my own what is awesome, and what sucks. I have put everything awesome together and wrapped it up into
BootPress, which of course I use for everything now. I just upgraded the Profiler to be as nice as Bonfire's (with a few improvements of my own). Ion Auth is good, but pretty bulky. Also, use GitHub! They make your life so much easier. realfavicongenerator.net I recently discovered makes really good favicons. That is all I can think of for now. Happy Coding!
