I think the same generic answer _does_ apply to most mature projects. Libraries like these should be approached like discussions about starting over in mature software projects; "this time we'll do it correctly", or "this framework is much simpler". This applies very much to libraries such as these.

When the complexity is low, projects are easy to learn, maintain and handle. That really makes them seem better and have advantages – advantages like a much reduced bundle size. But these new setups just don't do the same thing. It's a shell of what the old project did, as it's missing solutions for hundreds of edge-cases and other requirements that were tackled by the mature many-year old project that is maintained by some of the best developers. I'm sure React has a bit of bloat, but I'm willing to trust the React team that the vast majority of it is there for a reason. It might also be the cost of building on top of a very mature solution.

Would you not shut such a discussion down when someone new in the team proposes a complete rewrite?

Preact does not have 1:1 feature parity, if it had it would have been much more widely used (who wouldn't want a free filesize reduction?). Preact has plenty of issues, which is why it isn't as widely used.

I think this is an overly dramatic take. Of course react has a fixed overhead. If all you're deploying is the single button, then that overhead is for no benefit. But the overhead gets amortized over your entire app, which most likely has thousands of components. This is like a microbenchmark which only measures the static overhead. Not indicative of a real app.

There's an entire cottage industry of "react" but smaller frameworks out there. Somehow, none of them have caught on.

Preact is the one I'd go for if I wanted a smaller react because it's quite mature and it provides the same API.

> a single component outweighing an entire app feels fundamentally broken

It just doesn't to me, understanding that in react-land, a single component and an entire app will have roughly equivalent size, if you're not pulling in any other dependencies.

No one (I hope) would ever use react for a single button, so it feels like an unhelpful comparison.

I don't think that is fundamentally broken. React is just not the right technology for a single button, and it's not trying to be.

If you tried to use photolitography (the technology used to print the circuits in microprocessors) to do tattoos... well it could probably work, but it would be highly inefficient and expensive and bad.

React is for complex web applications, and it I don't think it's a very valid criticism to say that it is bad for a different use case. To some extent, the React community may have over-promoted React as the final web-dev framework, but that's also a mistake.

In any case, kudos on creating Nue, looks really cool, I'll keep an eye on it ;)

Is it really React or the stuff it lets you bring in? Many React apps have at least one big widget set (say MUI or reactstrap or …) and then a number of “best of breede” components that do various things. It’s rare for components to be styled with plain CSS these days so you probably have to bring in Emotion and styled-components and Tailwind and …. It is all code that goes into the bundle and it’s a burden on your mind because these are all leaky abstractions and don’t absolve you of understanding CSS.

If Preact truly was as feature complete as React, it would be used by everyone by now – it's old enough for most teams to be aware of it. The fact that it isn't widely used is case in point.
