something about using html attributes as a programming language makes me cringe a little. The toy apps look great and maybe where these can really shine, but seems like it may start to turn into a mess very quickly
People got so stuck on JS for decades that they've forgot that HyperText in HTML is there for a reason. It was always supposed to be more than just UI descriptor markup.
It is JS who is out of place in web. A little script in form of DHTML that grew into becoming a cancer that it is now.
Having used inline styles in the past, there is no comparison to tailwind. Tailwind is a good and productive, though certainly not ideal tool. But it’s miles ahead of whatever else has been produced by css frameworks, in terms of productivity and maintainability.
These "stacks" ONLY work if you are building hobbyist apps, or if you want to sell services. A fast-moving product company has many better alternatives that are probably far more tailored to their business objectives and team composition.
Maintaining these things in production for many years is often painful and cumbersome. Moreover, they usually are introduced by a single person who has a lot of enthusiasm to maintain it, but when that person leaves all hell breaks loose. Even more fun is when the underlying infrastructure provider decides to deprecate an API that requires a ton of bespoke fixes (e.g. Netlify's Next.js edge plugin which recently had a behind-the-scenes change to how Lambdas are spun up causing bugs with state leaking between requests).
With that said, it's good to explore new technologies. I just wish these sorts of posts (which are thinly veiled product marketing/tutorials) would expand to actual direction/feedback about how to use new tools in production effectively.
New tools are, by definition, new, and full of unknowns. There are roughly only two ways to use them in production effectively: either you understand what they are trying to do and take the risk because you are convinced it is The Way, or you wait until the tool/tech settles and becomes not so new anymore as the experience reports from the first group trickles in.
React is nothing like Vue or Svelte.
