Pop an image on screen — the gift/emote artwork, an uploaded asset, or any URL. Auto-removes after a few seconds.

// Show an image, then fade it out
TE.on('gift', function (ev) {
  var img = document.createElement('img');
  img.src = ev.gift.image;                 // ← any image URL works
  img.style.cssText = 'position:absolute;left:50%;top:50%;transform:translate(-50%,-50%);max-width:60%';
  document.body.appendChild(img);
  setTimeout(function () { img.remove(); }, 4000);   // ← how long it stays
});

Play audio on an event. Expose a sound setting so the streamer picks their own file — no code editing.

// Play a sound the streamer chose in settings
var s = TE.defineSettings([{ key: 'sfx', label: 'Alert sound', type: 'sound', default: '' }]);
TE.on('settings', function (ns) { s = ns; });
TE.on('gift', function (ev) {
  if (s.sfx) { var a = new Audio(s.sfx); a.volume = 0.8; a.play(); }
});

Write dynamic text and re-trigger a CSS animation by toggling a class.

// Announce the event with a CSS pop animation
var box = document.getElementById('box');   // your element in the HTML tab
TE.on('follow', function (ev) {
  box.textContent = ev.user.name + ' followed!';
  box.classList.remove('pop'); void box.offsetWidth; box.classList.add('pop');
});

Bind an on-screen number to a live metric — viewers, likes, coins, followers — updated automatically.

// Keep a number in sync with the live stream
TE.on('metrics', function (m) {
  document.getElementById('count').textContent = m.viewers.toLocaleString();
});

Speak an event with the browser’s text-to-speech. Great for gift or follow shout-outs.

// Text-to-speech shout-out
TE.on('gift', function (ev) {
  var u = new SpeechSynthesisUtterance(ev.user.name + ' sent ' + ev.gift.name);
  speechSynthesis.speak(u);
});

Simple synchronous persistence for visual state. Use the transactional runtime for entrants, purchases and shared scores.

// Persistent state: survives OBS reloads
var total = TE.store.get('total', 0);          // read (with default)
TE.on('gift', function (ev) {
  total += ev.gift.coins;
  TE.store.set('total', total);                 // write (auto-saved)
  render();
});

Exact-match chat commands plus atomic collections make safe entries, votes and spins possible.

// One server-authoritative entry per viewer
TE.onCommand('!join', function (c) {
  TE.collection.join('entrants', c.user.id, c.user).then(function (result) {
    if (result.joined) renderCount(result.count);
  });
});

Request overlay alerts, sounds, TTS, counters, subathon time or OBS scene switches directly from a widget.

// One call, one stream action
TE.act({ id: 'tts', message: 'New high score!' });
TE.act({ id: 'obsScene', scene: 'Hype cam' });        // needs the Desktop Bridge

Transactionally check, spend or award loyalty points and receive the resulting balance.

// Only spin after the points were really debited
TE.onCommand('!spin', function (ev) {
  TE.points.trySpend(ev.user, 50, 'Wheel spin').then(function (result) {
    if (result.ok) spin();
    else showMissing(result.missing);
  });
});

Atomic state, collections, secure random draws, cooldowns and persistent timers — safe across duplicate browser sources.

// Fair draw from a server-owned entrant collection
TE.random.draw('entrants', { count: 1 }).then(function (result) {
  if (result.ok) reveal(result.winners[0].value);
});

Expose text, colors, numbers, toggles — the streamer tweaks them live in the overlay editor, no code needed.

// No-code controls for whoever uses the widget
var s = TE.defineSettings([
  { key: 'title',  label: 'Title', type: 'text',  default: 'Goal' },
  { key: 'accent', label: 'Color', type: 'color', default: '#FF2E4D' },
]);
document.body.style.setProperty('--accent', s.accent);
TE.on('settings', function (ns) { s = ns; /* re-render with new values */ });
