I think Rollup already took time away from Ractive. It's really too bad, I think Ractive has some great ideas and I really enjoyed working with it. It was the best way to build web UIs I've come across. But I feel its future is uncertain so it's hard to recommend others begin using it.
Actually, ractivejs as it is right now is pretty mature, so I will still use it. The ecosystem and momentum behind it could suffer from a _shift in focus_ from /u/rich_harris- the creator of both libs- but the library has flown under the radar all this time so I feel it might not be a huge change.
Perhaps, but at least to the team I was working with at the time, Rollup indicated we shouldn't expect much to change or improve in Ractive. I think Ractive was partially a victim of timing; as Harris himself has said, it has many of the same ideas as React and he may well not have made it if React existed when he began. And it never really seemed to gain much popularity which you kind of need for a project to grow beyond just its creator. I still haven't investigated this new thing, but if it was indeed inspired by Ractive that gives me hope.
I'm wondering if Svelte will take away development efforts from ractivejs?
