Setup

bun add @bitstillery/mithril

Types are built-in; no @types package needed.

Basic application

Scaffold a project: bun init my-app, cd my-app, bun add @bitstillery/mithril
Add to package.json: "dev": "bun run --watch src/index.tsx"
Create src/index.tsx:

import m, {state, MithrilComponent} from '@bitstillery/mithril'

const $s = state({count: 0})

class App extends MithrilComponent {
    view() {
        return (
            <div>
                <p>Count: {$s.count}</p>
                <button onclick={() => $s.count++}>Add</button>
            </div>
        )
    }
}

m.mount(document.getElementById('app'), App)

Create index.html with <div id="app"></div> and <script type="module" src="src/index.tsx"></script>
Run bun run dev
