Here's a great check list for frontend performance: https://github.com/thedaviddias/Front-End-Performance-Checkl...

I love checklists but you may end up with people dumbly following them.

That may be good when a checklist is accurate.

Unfortunately models work in the constraints and simplifing assumptions they were built in.

"Web development" it is a pretty large subject to cover. Best practices for dynimic site that is image heavy do not match best practice for systems that is heavy in static content.

A check list for web delopment is going to be pretty messy if you want to account of all cases.

But maybe it is worth giving it a try...

Include an item on the performance checklist about not blindly following items on the performance checklist.

Now nobody who follows the checklist completely could be doing so blindly.

There are boilerplates that encapsulate best practices for some use cases but they may end up obsolete after a year or so...

> so many built on outdated/inferior tech

So you update all your apps/websites to the latest/superior tech?

Also, a simple jQuery + HTML frontend is in most cases way more performant then the "modern" mess that webpack generates.
