Hear about something new, then immediately hear about its multiple successors/replacements.
Check it out, it's the kind of framework you pick and stick with for 20+ years. Zero bullshit compared to its peers.
Good frameworks are good, and I love a good hobby project in some new hotness, but ecosystems, developer tooling, backward compatibility guarantees, large corporate backing, developer conferences, and community are what makes frameworks adoptable are what makes them stick.
Your heuristic that a large ecosystem is what makes a framework good precludes you from ever again touching any new project. It's a short-sighted approach.
At some point, you have to grow up as a developer and try to understand the real world problems that modern declarative web frameworks have solved. I stated that mithril will be my tool of choice for hopefully 20+ years, so your framing this as me getting lost in the new hotness doesn't even hold up. This is about real tools, which are useful today and tomorrow, and which have slow API churn to facilitate longevity. It's just a bonus that mithril is also faster and far more terse than React and friends.
- mithril.js is an actual web framework. I’ve not tried it myself. - the next comment referenced adamant as being better. There is an MMORPG called RuneScape in which weapons and armour can be smithed of various metals, and treats adamant as 1 tier better than mithril. - similarly orichalcum is a couple of tiers above mithril.
