      I use React sure, but I don't feel particularly defensive about criticisms of it when they actually make sense. But blaming a 400KB bundle on the fact that the user used React is a bit absurd to me and makes it really hard to take anything Alex says seriously on that front.

      I think that it's wrong to blame React, because that isn't the conversation. It's not wrong to observe that people assume that React is "fast enough" and that there's too little discussion about techniques that should come default across the board.

      Also, I don't "blame" React. Instead I note the probability (approaching 1) that sites with 400K of 1P JS include a relatively heavy framework, too many polyfills, and many other unneeded elements. Heavy FW use is a symptom of broken culture and management priorities.

      Define heavy? React is < 10% of that 400K. If you really want to make this better, *here's* the battle to be fought:https://twitter.com/AdamRackis/status/1040029445179039744 …

      If any dev advocates want to help reduce bundle sizes across the web, a great first step would be to encourage major libraries to stop shipping un-tree-shakeable CJS to npm. Ship real ESM (import and export), and let webpack and Rollup do their thing ❤️👊🔥

      Another piece is figuring out how to model async fetching in frameworks so that simply using popular routers in the normal way gets you a decent amount of code splitting.

      Ooo, Vue is a prime example of this. Allow component to component registrations to accept `() => import()`, allow routes to accept `() => import()`, anywhere you import modules for your framework, should also have the capability to wire up those same dependencies w/ `import()`.

      It’s important though that you can do it for heavy leaves without showing spinners or holes for these leaves. That’s how React implementation is different and I hope more libraries take note of this.

      Is there a succinct description of what you hope I take note of? I'm paying attention! :D

          Sure. Basically any leaf can suspend rendering. Including due to code splitting. But we don’t show the spinner necessarily where it suspended. Instead we let you specify <Placeholder> *somewhere* above. Making your loading states intentional, not an artifact of bundle split.

          So you can have <Placeholder fallback={<Spinner />}> <Modal /> </Placeholder> And then somewhere deep in the Modal there is Autocomplete. If it’s code split, React can show spinner in Modal backdrop — or even next to Button that caused Modal to show.

          This means that you can code split more at any point in time — for example to load ModalHeader — without worrying about changing design. You already have a Placeholder. It will wait for both ModalHeader and Autocomplete as it tries to render Modal.

          As a bonus, in concurrent mode we can skip showing the spinner altogether if it loads fast enough. We don’t show holes either. We just show the complete Modal if it’s ready fast enough. That’s what Fiber architecture allows.

          The modal example is fun because it means you’re not constrained by DOM hierarchy. If modal is a portal from some form, loading state for thay modal can be handled that form. Even though technically it’s top level body child in the DOM.
