Web components were hailed as the future of UI development, but they’re no silver bullet. In many senses they are a compromise, but they come with some really good parts which even the biggest web components' skeptics would find it hard to argue against.

In this talk, we'll focus on the good parts of web components, based on an R&D project we did at SuperTokens, trying to answer the question - How do we ship pre-built auth UI that supports every web framework out there?

We'll have a closer look at the custom elements API, tradeoffs when using the Shadow DOM, and modern DX tools, such as solid-element. Additionally, we'll have a look at some alternative approaches to this problem, such as Mitosis.
