Although the project is written in typescript and in a way it will work in Deno, you still need a Deno version of DOM like Node jsdom package and it is a working in progress to have things running in Deno in near future.

Yes! You can check the getting started guide for Node for more details.

Not in the way we want yet. You can run CWCO in a Node server and render things but they are still encapsulated inside the component tag you create and need a client side CWCO to handle the tag.

We are working in a support that exposes the internal content of a component and it is handled in the client in continuation of what was done in the server.

There is one in the works. You can follow this guide for an alternative solution meanwhile.

CWCO is no longer in beta mode and it is actively being supported. We can work with you if you take it into production and something bad happen. We are confident that you will be fine

There is no official benchmarks numbers to share but the numbers look better than few alternative libraries you can find out there.
