Filed under "it's likely hopeless, but..."
I'm beginning an exploration of LitElement and web components. I've been heavy in Angular, React, Gatsby, and HyperApp. Since I'm currently deep in Gatsby, I'm thinking about SSR, PRPL, and "first render".
More specifically, I come from Python. It's hard if you're not running Node on the server and get SSR and first render. This document talks about it.
