Examples

Thirteen runnable example apps ship in internal/examples/. Each is a single main.go you can read in a sitting and run directly:

go run ./internal/examples/chat
# open http://localhost:3000 in two browser windows — messages sync live

⭐ The flagship is chat — a live multi-user chatroom in ~60 lines of Go, no WebSocket and no client JS, walked through step by step in the tutorial.

Example	What it teaches
chat ⭐	A live multi-user chatroom: an app-scoped event log (StateAppEvents) folds each Posted event and fans the new line out to every connected browser — no WebSocket, no JS.
counter	StateTab[int] + Signal[int] + a typed action — the canonical first app.
greeter	A Signal[string] mutated from two distinct actions.
pathparams	Typed path:"id" decoding into composition fields.
countercomp	Two independent counter compositions nested on one page; isolation across instances.
counterscope	StateTab[int] (tab-local) vs StateApp[int] (shared across every session) side by side.
picocss	picocss.Plugin() driving theme + dark-mode switching on the client without a reload.
auth	Typed sessions, requireAuth middleware, and sess.Rotate after login.
todos	StateSess[T] survives reload, h.Each, and on.SetSignal for client-bundled writes.
sysmon	An OnConnect-driven ticker streaming CPU / RAM / disk / net into ECharts, with a pause + interval-slider UI via via.Ticker.
maps	maplibre.Plugin() driving an interactive world map — city fly-to, a ticker-moved “drone”, click-to-place pins, marker & feature clicks, hover highlight, and popups, all from Go over SSE.
upload	A via.File field bound to a multipart/form-data <form>, persisted to disk with a redirect back.
feed	An append-only / bounded-ring slice stream driven by Signal[[]T].Update, paused and cleared from actions.
