The page you're reading is served by the C MVC framework. Pages that need interactivity declare a data-lua-module attribute on the body. A wasmoon-compiled Lua engine boots in the browser, fetches only that module, and runs it. No virtual DOM, no React. Signals + hyperscript, ~180 lines of lua.
A single signal driving a text node and two button handlers. The whole demo is ~20 lines of lua.
Run demo →-- pages/counter.lua
local count, setCount = reactive.signal(0)
local root = h("div", {},
h("p", {}, function()
return "Count: "..count()
end),
h("button", {
onClick = function() setCount(count()+1) end,
}, "+")
)
dom.mount(root, "#app")-- pages/todolist.lua
local items, setItems = reactive.signal({})
local draft, setDraft = reactive.signal("")
reactive.effect(function()
list.innerHTML = ""
for _, v in ipairs(items()) do
dom.append(list, h("li", {}, v))
end
end)A reactive.effect re-renders the list whenever the signal changes. Input wired via dom.on event bridging.

The page weight line above is real. Pages without data-lua-module ship zero wasmoon — boot.js returns early. The framework JS is only fetched once per origin and cached.
