React's Next Big Change?

react-dom is a criminally under appreciated part of how React works. react-strict-dom makes understanding it even more important. Excited for this library and how it could impact the world of React Native.
Is this the opposite of Flutter?

[@spicynoodle7419]

Yes

[@alexisfibonacci]

JSX requires capital letters for such tags if you are not using the "implied native DOM elements". html.div is allowed some weird rules around access the elements of an umbrella object.

[@gedw99]

It’s similar to what hyperview is which is based on htmx. Instacart built hyperview so they could target web and native with 1 dom definition that is augmented at runtime , not compile time .

[@CurlyCow]

I think you're confusing some stuff here. They can't rewrite the event loop or control it in any way. What they can do and are probably going to do is write a scheduler that determines the optimal way to distribute work across the various event loop queues. You don't get to touch the behavior of the event loop in JavaScript land. Its implementation is lower level than that, think V8 C++ code.

[@shadeblackwolf1508]

I get one codebase, many targets may not be ideal, but one codebase defining the presentation independent behavior across those environments, yes please

[@echobucket]

Yay, let's just add even more abstractions.

[@nowayicommented1314]

you got me good with calling out those who skipped to react-strict-Dom xDD

[@Novacification]

StyleX is such an unnecessary abstraction in my opinion. CSS is not rocket science and if you're getting unintended side effects from your changes, it is very likely because your HTML structure is ass. And before anyone starts; yes, I work on a large product. Issues with CSS is a great reason to actually look at your DOM structure and identify needless complexity. React is especially bad with messy DOM trees because your components obscure excessive nesting of HTML elements and makes it easy to leave shit behind if you don't wrap your conditional renders correctly. I'm not saying CSS doesn't take time to learn and lord knows there are many, many quirks that can cause unexpected behavior (though it is a lot easier now than it was 10-15 years ago). Of all the problems I encounter with HTML/CSS, targeting and property inheritance are not the main ones by far. Certainly not enough to warrant another abstraction. I've seen people mention that being able to have your styling in the same file as your component code is a benefit. Why people think this is beyond me. Even if I was to use StyleX I would always separate my styling into another file to avoid visual clutter. Multiple files are much easier to navigate than a single file with several different contexts.

[@prozacgod]

I've always wondered if react-dom was extensible, where I could supply my own objects in the create element, but it's probably so tightly coupled to dom that it might be more complicated than that.

The NPM trends thing is cool - but there are two points where installs are always lower - one is 24/12 being Christmas (eve), but the other pit is 29/10 - why is that? What happens at the end of October to cause such a dip? I looked it up, and I found it to be International Internet Day, National Cat Day, World Psoriasis Day, World Stroke Day, and my favorite - National Oatmeal Day. It's also the day Matthew Perry died.

[@JamonsCodeQuests]

There’s a lot of React competitors popping up, but none of them consider other platforms. It’s so awesome to see the React team taking every other platform super seriously. Thanks for the synopsis, Theo!

[@mrgalaxy396]

That's because the market share of the web is over 90% if you just compare the install rates of the target platforms from the video. There are also emerging solutions for platform agnostic implementations as well. Really React now is more akin to Java trying to stay relevant with its "targets anything that can run a JVM" when better solutions emerged.

[@gedw99]

Styled embraces the locality of behaviours that tailwind and htmx are doing . Ironic. Reminds me of how he react server components allows SSG and SSR like htmx does by its very nature. I am not against at what meta is doing. I am just noting the change in mindset back to a dom for each target being more groksble and the attempt by meta for a fully qualified dom that works across different device targets just like what hyperview does. The thing that most interests me is actually exposing these API as a plan9 style approach where everything is a file approach works. With rendering systems you can do the same approach and expose dom as a file like api or a http web transport target that is callable rom the runtime. This is a common namespace structure into the dom itself and the style itself, so that it’s easy to alter the DOM at runtime . Kind of a bit like a asyncapi of the DOM itself. It’s all going o be interesting how Wendy and quest and Apple vision pro fits into this picture and the DOM that will be exposed for a 3D DOM. This is where the abstraction layers and an async api over them will be a key differentiation. Apple has Pixar and its UDSZ format that has the right mix of namespace aspects to make it parametric. The new Model DOM for browsers is still a long way away and will never get cross browser support. A 3D higher level abstraction layer will be needed with a restricted DOM and Style that works on many runtimes. Then we have Unity and unreal engines to through into the mix. The software world needs a way to abstract all these targets and these attempt are great. It’s really just what is called “ single sourcing” where one dom works on many targets. I think a WASM runtime that does the translations at runtime and / or compile time one opportunity here. WASM runs everywhere ( browser, native, a Vision Pro app ) a server , a cloud flare function too. I don’t hold out that much hope for this shift by Meta because their are other frameworks doing this from a fresh start hat learnt from he mistakes in react . Let’s see

[@Aleks-fp1kq]

wait a second, that is not virtual DOM, that is react component tree, which in turn is rendered to the virtual DOM, which in turn is synced with the DOM.

[@jinx.love.you.]

That has such a huge implication that if this happens the paradigm of development will completely shift from opening Web Developer to Mobile in a Direct term. This means that React can then be used for different platforms even for VR (Quest/Vision) as it should technically be adaptable as it gonna be an integration to a model that already does it. I am really not good enough to contribute... but Thanks to those who does.

[@SohelIslamImran]

Awsome

[@CouchProgrammer]

Cool. I don’t know for what purpose this “html.div” was made, probably due to the fact that typings for jsx div are declared globally. Adding global elements via react hyperscript is not a new thing. The only problem is that typescript does not allow you to specify different global scopes for different files. The next step will obviously be to go to Microsoft TS and push global file (module) level scopes. Well, then rewrite all the garbage that they are going to write using "html.div" back to javascript. Or maybe someone will figure out how to use partial grammars without dancing with a tambourine.

[@PieterWigboldus]

encapsulating the style is a downgrade, because you'll always need to customize the appearance of the components you use, and with encapsulation the only way to do it is via props. This means more work for libraries mantainers, more work for the developers and less customizability, that is also the problem of native development.

So much bitching in the comments over something that is still strictly in the research phase and will probably not impact you at all unless you want to use it in the future.

If you, as a professional or even novice dev, cant keep up with a release schedule with small breaking changes that can almost be measured in half-decades, you are NGMI. Sorry.
