Stencil and consequently Ionic are all Web Component based.

Svelte fully supports compiling to Web Components with 100% test coverage.

Vue fully supports Web Components as well, the only issue I've run into there is with CustomEvent.detail not being copied into the Vue event payload properly.

Web Components are widely used on the web, just under the covers sometimes.

VueJS actually fails some advanced tests for WebComponents: https://custom-elements-everywhere.com/

So, VueJS docs are actually incorrect when they say it scores 100%. The actual score is 91%.

I had reported this 8 months ago.

For people too lazy to look into what the issues are: lack of support for CAPScase, camelCase, and PascalCase DOM events. Only lowercase and kebab-case work.

Why is this getting downvoted? Did I miss something? I only found those 6 errors (each occurs in two tests, so 3 types)

Svelte will remove compiling to web components into a plugin.

In general, none of the major frameworks, and very few of the new frameworks use web components as a foundation for their functionality for many extensively described reasons that wc proponents literally couldn't care less about.
