Ask HN: Best tiny JavaScript framework?

PX2: https://github.com/burtonsamograd/px2

A better designed version of Backbone with a small footprint.

I designed tko (https://github.com/knockout/tko) to make it easy to re-use the best parts of Knockout using tree-shaking ES6 imports.

When experimenting with substituting a few modules, I've gotten it down to 4.5k gzipped.

It's still quite early on (alpha), but already some folks are using it in production. Plus, it's mostly backwards-compatible with Knockout.

While it might not be an ideal, usable solution for this problem yet, it's definitely moving in the direction of filling exactly this niche (among others).

How about basically no framework with svelte? https://svelte.technology/

Svelte is a framework... that disappears at build time.

Vue is really small: 18kb min+gzip is tiny compared to the competition.
