partials

Partials Example

Showcases server-rendered partial fragments and manual boundary replacement.

Key files:

• index.html defines a product boundary and load button.
• main.js registers a server function, async partial, and click handler that renders then swaps the partial result.

Start from the repo root:

python3 -m http.server 4173

Open http://127.0.0.1:4173/examples/partials/.

Verify:

pnpm run examples:check

Why the handler captures runtime

Delegated handler contexts expose signals, handlers, loader, server, cache, and scheduler — but not the partial registry. Rendering a partial from a handler therefore reaches the runtime through the module-scope runtime binding. This is the intended pattern for partial-driven swaps today.
