I had a look at Svelte in the early days but went with something more mature for the project at the time. I actually recently landed on Sapper while looking around tab Web Component projects and it looks good, though I haven’t had a chance to try it out yet.

edit: also, read a lot of comments about "why the military tagline". It's a play on the name Sapper. An old buddy of mine is one up in the CAF in Edmonton. They're combat engineers— hence the military tag.
