I like a lot of what JSR offers, I do hope that it sees a fair amount of uptick. I've been using Deno a lot more than Node lately, mostly in that it's better for shell scripting with a shebang and direct imports compared to package.json and node_modules etc.
I'd like to see a few things get refactored to work better over time, but who knows.
I wasn't too bullish on Deno because of the lack of a good package manager, but now I'm excited about JSR as well, it's cleverly architected, and everything in that talk made sense to me
That's understandable... I actually kind of appreciated the use of HTTP(S) references for code with Deno.. though a repository is nice enough. The x.deno.land worked, but JSR is definitely a better longer term solution, and really happy to see decent npm support.
Thinking about a minor rewrite of a couple modules this weekend to be JSR first, adding enough for an npm publish to remain working.
