Dacast JavaScript API

Overview

The Dacast Player exposes a global window.dacast object. Use the dacast() function to initialize a player, then control it via the player instance or postMessage (for iframe embeds).

JS file: https://prod-player.dacast.com/js/player.js

1. Initialization

const player = dacast(contentId, containerId [, options]);

PlayerOptions

Example:

<div id="my-player"></div>
<script>
  const player = dacast("abc123", "my-player", {
    width: "640px",
    height: "360px"
  });
</script>

2. Player Instance API

After initialization, the player is also accessible globally:

const player = window.dacast.players["your-content-id"];

Note: The player object is available immediately, but methods are no-ops until the player is ready. Use onReady() to safely call methods after initialization.

Methods

ContentInfo Object

{
  contentId: string
  title: string
  description: string
  splashscreenUrl: string
  thumbnailUrl: string
}

Example:

const player = dacast("abc123", "my-player");

player.onReady(() => {
  player.seekTo(30);

  const info = player.getContentInfo();
  console.log(info.title, info.description);

  player.dispose();
});

3. Player Events

Subscribe with player.on('event_name', callback) or player.onEventName(callback) — both return a Subscriber.

Unsubscribe with player.off('event_name', callback) or subscriber.unsubscribe().

interface Subscriber {
  unsubscribe: () => void
}
