[0x03] WEB // BROWSER_RUNTIME

Lua, in the browser, mounted per route.

Pages that need interactivity declare a data-lua-module attribute on the body. A wasmoon-compiled Lua engine boots, fetches only that module, and runs it. No virtual DOM, no React — signals + hyperscript in ~180 lines of Lua.

Reactive counter

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")

[demo_02]

Mutable list with effect

A reactive.effect re-renders the list whenever the signal changes. Input wired via dom.on event bridging.

Run demo →

-- 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)

02 // RUNTIME_TOPOLOGY

Pages without a module ship zero wasmoon.

boot.js returns early when the body carries no data-lua-module. The framework JS is fetched once per origin and cached; every page module after that is under a kilobyte.
