What if HTML was enough?

Traditional Stack

// api/counter.ts
import { db } from '../lib/db'
export async function POST(req) {
  const session = await getSession(req)
  await db.counter.increment(session.id)
  const count = await db.counter.get(session.id)
  return Response.json({ count })
}

// components/Counter.tsx
'use client'
import { useState } from 'react'
export function Counter() {
  const [count, setCount] = useState(0)
  const increment = async () => {
    const res = await fetch('/api/counter',
      { method: 'POST' })
    const { count } = await res.json()
    setCount(count)
  }
  return <button onClick={increment}>
    +1 ({count})
  </button>
}

<!-- site/counter.html -->

<p>Count: #session.counter|default:"0"#</p>

<button w-set="session.counter += 1">
  +1
</button>




That's the whole file.
No API. No state library.
No build step.
