This is a neat page that compares a ton of different libraries with web components. One of the things I learned after posting “A Bit on Web Components Libraries” is that the web platform APIs were designed for libraries to be built around them. Interesting, right?

This page makes a counter component. By extending HTMLElement natively, they do it in 1,293 bytes, then each library adds things on top of that. The big libraries, like Vue and React, are clearly much bigger (but bring a ton of other functionality to the table). One of the biggest is CanJS (230,634 bytes), which isn’t aiming to be small, but, from their about page: “It targets experienced developers building complex applications with long futures ahead of them.” If the goal is small, Svelte is true to its mission of nearly compiling itself away ending at just 3,592 bytes, a third of the size of the super tiny lit-html and half the size of uhtml — both of which are just tiny abstractions that offer nicer templating and re-rendering.
