Handling data
React passes all data to Custom Elements in the form of HTML attributes. For primitive data this is fine, but the system breaks down when passing rich data, like objects or arrays. In these instances you end up with stringified values like some-attr="[object Object]" which can't actually be used.
Handling events
Because React implements its own synthetic event system, it cannot listen for DOM events coming from Custom Elements without the use of a workaround. Developers will need to reference their Custom Elements using a ref and manually attach event listeners with addEventListener. This makes working with Custom Elements cumbersome.
This is a pain point of React + web components, but I’ve heard they’re trying to solve it in the next major version. In the meantime, I built a wrapper that lets you use custom elements as if they were React components. [1]
