VeloJS

SSR notes

VeloJS renders Preact through `preact-render-to-string`, stores request data in AsyncLocalStorage, and hydrates loader data for client navigation. Production builds produce a client bundle plus a server entry.

Islands notes

The documented architecture hydrates the routed application rather than exposing island-level partial hydration. Choose a framework with explicit islands if minimizing client JavaScript per component is the primary requirement.

Add the VeloJS plugin to `vite.config.ts`. Route components are ordinary Preact components, while the plugin analyzes route modules and generates separate client and server entry points.
