I'm genuinely curious what others are using to solve the real world problem of consuming a design system's components in existing applications that are in various tech stacks? Suppose you're building components to be used in Angular, React, Vue, [whatever hot new framework].
Are you using Stencil to build Web Components? Is Svelte viable?
I'm super curious about this as well.
A few months ago, I worked on a design system project where we faced this question and decided to focus on CSS only, at least to start. We followed Bulma's example and instructed developers to add classes like is-active or is-loading using a framework of their choice. More complicated functionality will probably require web components or something similar - think data tables, date pickers, etc. - but vanilla CSS isn't a bad place to start.
Here are some examples of what other design systems are doing:
Carbon looks to be experimenting
I think a major point is that web components are low level API that are unconcerned about where they live. At least with LitElement based web components that we've built. I can't speak for every method used to create them because I believe lit-element and lit-html were built with the goal of eventually making those libraries unnecessary as more gaps get filled in browser specs.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
