Bundle Size Comparison

Bundle size of 1 component

If you only deliver a single <my-counter/> you have the full cost of the library for a single component. This is the total cost of a single component with the library included.

Estimated Bundle size of 30 components using the same library

This is an estimated size of a bundle of 30 my-counter-like components using the same library. All components will share the library code so the estimated size is calculated with: 1 bundle-with-dependencies + 29x components-without-dependencies.

Performance

First Contentful Paint

The First Contentful Paint is benchmarked with Tachometer.

The benchmark page is composed of 50 <my-counter></my-counter> laid out in a single page with the library bundle code inlined.

Notes

Take into consideration that there is a margin of error of 2-3ms.

Things that play a role in this performance figure are:

The size of the JavaScript to parse (bigger = longer).
The performance of the library to create the DOM nodes from scratch.

Everything runs locally so the network download time is not taken into account here.

Everything runs on a relatively powerful laptop and results could be completely different on a lower-end device like a phone or a tablet.

Unfortunately, for technical reasons, we couln't include

Angular 9 Elements
Stencil
Vue.js

Stay tuned for the next update!

Final Notes

It's hard to find so much diversity in a technical solution. It tells a lot about Web Components and the low level API provided. All the 30 variants could be on the same page if we wanted to!

On bundle size, the results are already very promising but there is still room for improvement:

Some libraries would benefit from splitting their features, to better benefit from tree-shaking.
Except Stencil and Svelte, none of the libraries offer CSS minification out of the box.

Web Components are well supported in browsers now. Still, for old browsers (including IE11), polyfills are required. The bundle sizes reported here are only for modern browsers that don't need any polyfills. It was too much additional work to include polyfills in this post. Maybe later... before they become obsolete.

We will report on new libraries and updates. Make sure to follow us on Twitter.
