Ah yes, Svelte. What we're witnessing is a mass migration from an established society with great infrastructure, education, governance and stability moving to a barren uninhabitable land of opportunity and unlimited possibilities albeit full of traps, broken pipes, dangerous bugs and vicious wildlife. Troves-full are jumping on these new bandwagons, cramming themselves in, clueless but hopeful from the allure of a far promised land of the wild wild west.
1) React also didn't have any of that when it started.
2) The "ecosystem" is a fallacy. It's merely used as propaganda, to win popularity arguments and to dismiss new technologies. 99% of the packages on the so-called ecosystem are badly written, unmaintained shit, and most projects don't really need third-party packages other than React/Redux anyway. Especially projects that have a dedicated designer using Figma.
I was mostly mocking how fast JS ecosystem moves. Evidently, HN didn't find it funny. Just about the time we have a matured React framework, we've got another framework to jump to.
Why do you confuse a little bit of HN enthusiasm for mass exodus? Does it surprise you that the most vocal people on a forum of craftspeople are the ones in the honeymoon phase of new tools?
If you've been around for more than a few years, you've had plenty of opportunity to see how inaccurate this extrapolation is, like how HN enthusiasm for Elixir doesn't mean that more than a tiny fraction of us are using Elixir.
It's just kind of boring to hear someone complain/jest about "haha developers = lemmings seeking shiny amirite? XD" over and over again, thinking there's some novel witty snark to be had by repeating it for the millionth time. It's also confidently wrong. Most people aren't migrating to new tools just because some people are excited.
I mean, in 5 years Svelte could be the new React, and React could be the new Angular. I mean that there are plenty of people still using Angular for legacy apps, but it's not exactly "in vogue"; trends showed that people were generally more satisfied using react. React isn't going away, but if people are more satisfied with svelte (which the trends seem to indicate, and I understand why after learning a bit about svelte from a React background), I think it could dominate new projects in 5 years.
