Waku v0.27.1 is here! A React Server Component framework!
I've been wondering how to implement this, but now it's done!

Waku now supports custom base. Here is an example of SSG site deployed to Github Pages hi-ogawa.github.io/waku-example...
`@vitejs/plugin-rsc` takes care of base path for handling static assets, so the required change on Waku was only application routing logic github.com/wakujs/waku/...

> Waku has pioneered RSC framework implementation on Vite and provided many insights for the official Vite plugin.

Many APIs in the vite plugin are inspired by Waku. But, it's done right. When I started developing Waku, Vite didn't have Environment API.
Migration to @vitejs/plugin-rsc — Waku
Waku adopts Vite's official RSC plugin and Environment API as its foundation.
