As a Rails dev, I find this very interesting. I've already jumped on the Vue bandwagon and have had a pretty good time using it. That being said, I recently started a new small-ish Rails project and loaded Vue in via 5.1's Webpack integration...and ended up just hacking together some jQuery stuff for minor front-end dynamism. It just was easier/faster for me to do that in this particular context.

However, I could definitely see myself using Stimulus instead because it's just so incredibly simple to "sprinkle" (DHH's word) some JS onto the page and get dynamism quickly. I look forward to putting Stimulus through its paces and see if it is a good option for projects where Vue is overkill.
