Everything you need to build apps that live inside posts.

<!doctype html>
<html>
  <body>
    <button id="btn">0 taps</button>
    <script>
      // The runtime injects window.embedpad before your code runs.
      const btn = document.getElementById('btn')

      embedpad.room.subscribe((state) => {
        btn.textContent = (state.taps ?? 0) + ' taps'
      })

      btn.onclick = () => {
        embedpad.room.set('taps', (embedpad.room.get('taps') ?? 0) + 1)
      }
    </script>
  </body>
</html>

embedpad.player
// → { id: "k2v9x0qa", name: "guest-k2v9", color: "#00ba7c" }

// Let people pick a display name (max 24 characters).
embedpad.setName(input.value)

// true when running inside a post (or any iframe)
if (embedpad.inX) document.body.classList.add('compact')

// Wait for the first sync before reading.
const state = await embedpad.room.ready

embedpad.room.get('score')          // one key
embedpad.room.all()                 // a copy of every key

await embedpad.room.set('score', 42)       // any JSON value, up to 8 KB
await embedpad.room.remove('score')        // same as set(key, null)

// Called right away with the current state, then on every change.
const stop = embedpad.room.subscribe((state, changedKeys) => {
  if (changedKeys.includes('score')) draw(state.score)
})
stop() // unsubscribe

embedpad.players.subscribe((people) => {
  counter.textContent = people.length + ' here now'
  avatars.innerHTML = people
    .map((p) => '<span style="background:' + p.color + '">' + p.name[0] + '</span>')
    .join('')
})

embedpad.players.list() // last known list, no network call

// localStorage works even inside the sandbox. If the browser blocks it,
// the runtime swaps in an in-memory copy so your code never throws.
localStorage.setItem('muted', '1')

// Per-device settings → localStorage
// Anything other people should see → embedpad.room
