The vitriol on this thread is surprising and disappointing, but I can reassure you that it's also uninformed: re-posting things that have received little or no discussion, after some decent interval, is a norm on HN and is encouraged.
It would be a bad idea to post this story again in another month, but your last post got no comments at all, so this is presumably totally legit.
If a story has had significant attention in the last year or so, we kill reposts as duplicates. If not, a small number of reposts is ok.
The reason is that there's so much randomness in what gets seen on /newest and thus gets a chance at the front page. Allowing a few rolls of the dice is a way of mitigating that randomness and increasing the best posts' chance at getting attention, which is a top priority here. So we don't penalize reposts as dupes until that happens.
Edit: please don't take the pushback personally. JavaScript fatigue and framework fatigue have become trends over the last year or so. That's probably why the discussion is a bit more cranky than the median. Criticisms like 'ego' are totally out of line; neutral questions like "What problem does this solve" are of course fine.
