Bootstrap 5 will remove jQuery as a dependency

But this isn't replaced with a new framework that uses the shadow DOM, it uses the same techniques as jQuery, except without jQuery.

jQuery already uses many native features when supported, while also working around browser quirks and such. It's less of an issue than in the past, but it hasn't gone away completely; see all the comments/fixes for specific browsers.

Of course not. It's a return-of-investment calculation. The 85k of jQuery isn't all that large, especially considering that websites like Medium and NYC load 2MB of JS, and the overhead of jQuery compared to standard JavaScript is minor.

in the world of web performance and SEO 85kb is very significant. i wouldnt think twice to remove it if i had the opportunity. compared to modern frameworks, jquery is ~500% larger. you could definitely debate the usage and needs but thats a separate topic than efficiency.

These massive compressed JS bundles make me think your numbers are off on the alleged golden age of modern frameworks:

It’s not hard to beat jQuery in many cases but they’re looking pretty svelte in comparison:

Just because others do bad things doesn't make it OK for you to do bad things.

The biggest complain I read about is javascript downloads being so big nowadays so piling on with jQuery--or anything else--just because frameworks and other libraries are so bloated doesn't make it OK.

Look, I’ve replaced plenty of jQuery with vanilla JS. I’m totally on board for lighter, leaner pages. My point was simply that there’s this tedious cycle where people crap on the older tools and say everything is better across the board with the current hotness without actually measuring anything. There are a lot of cool capabilities we can use now but they’re only going to be better at the things you actually measure & attempt to improve.

If you don’t profile your app, that cool new stack is probably going to be bigger and slower because tools like webpack make it easy to manage tons of code and you won’t notice until you test it on mobile, slow WiFi, etc.

The "cool new stack", in this case, is native, vanilla javascript that works everywhere without downloading anything and without a need to learn someone else's library.

Or, if you actually read the thread you’re replying to, “modern frameworks” where none of that is true.

Uh, at least in terms of react a bit of quick googling saw people who were putting effort into optimizing react's client side size getting it down to ~40 - 90 kB, so it seems pretty comparable. Some of these folks had a 1.2 MB script bundle they were sending to the client to begin with.

I'm not in the trenches with this stuff though so my numbers may be wrong but... the ~500% number seems pretty off.

https://gist.github.com/Restuta/cda69e50a853aa64912d react is 31kb vue is 20kb preact is 4kb. depends on the framework but 500% isnt far off

The standard download of Vue.js is 95k; React is 120k.

I have no idea where you got your "500%" from, but it seems wildly off-mark.

JQuery Minified and GZipped is also 30KB: https://mathiasbynens.be/demo/jquery-size

When doing comparisons, don't be disingenuous. Compare like numbers.

Plus Vue.js 2.6.6 is 91K, not the 63K of 2.0.3 in that comparison.

It's easy to "win" internet arguments like this rolls eyes.

whoops i assumed the 85k was already gzipped. fair enough
