    • Choosing a <MediaFile> based on the browser environment
    • Loading/initializing a <MediaFile> (including VPAID creatives)
    • Firing VAST tracking pixels/impressions at the correct time
    • Opening VAST <VideoClicks> when appropriate

    API

    main exports

    VASTmanka(container:Node, [config]:Object) extends EventEmitter

    • Parameters
      • container:Node: A DOM node into which the ad will be inserted. The ad will take up 100% of the width and height of the container.
      • optional config:Object: The following properties are supported
        • config.vast:Object: Configuration for fetching VAST ad tags
          • config.vast.resolveWrappers:Boolean: true if VAST <Wrapper>s should be fetched automatically. Defaults to true.
          • config.vast.maxRedirects:Number: The number of VAST <Wrapper>s that are allowed to be fetched. Defaults to 5.
        • config.tracking:Object: Configuration for firing tracking pixels
          • config.tracking.mapper:Function: This Function can be used to transform the URIs of VAST tracking pixels. The Function will be invoked every time a tracking pixel is fired, with the URI of the pixel as the only argument. The returned String URI will be fired. Deaults to an identity Function.
    • Methods
      • load(uri:String) => Promise: Fetches a VAST ad tag and loads one of its <MediaFile>s into the container. The returned Promise will be resolved when it is safe to start playback via startAd().
      • startAd() => Promise: Starts playback of the ad. This method may only be called once. The returned Promise will be fulfilled when the ad starts playing. This method cannot be called until the Promise returned by load() is fulfilled.
      • stopAd() => Promise: Stops playback of the ad and cleans-up its resources. Once this method has been called, the ad cannot be started again via startAd(). The returned Promise will be fulfilled when the ad's resources are cleaned-up. This method cannot be called until the Promise returned by load() is fulfilled.
      • pauseAd() => Promise: Pauses ad playback. The returned Promise will be fulfilled when the ad pauses. This method cannot be called until the Promise returned by startAd() is fulfilled.
      • resumeAd() => Promise: Resumes ad playback. The returned Promise will be fulfilled when ad playback resumes. This method cannot be called until the Promise returned by pauseAd() is fulfilled.
    • Properties
      • container:Node: The supplied container.
      • config:Object: The supplied configuration, with defaults applied.
      • vast:VAST: A vastacular VAST instance representing the fetched ad tag.
      • ready:Boolean: Indicates if the ad is ready for playback.
      • adRemainingTime:Number: The amount of time (in seconds) left in the linear ad. Accessing this property before the ad is loaded will throw an Error.
      • adDuration:Number: The total duration of the ad (in seconds.) Accessing this property before the ad is loaded will throw an Error.
      • adVolume:Number: Gets/sets the volume of the ad with 0 being completely silent and 1 being as loud as possible. Accessing (or setting) this property before the ad is loaded will throw an Error.
    • Events: All VPAID 2.0 events are supported. A subset of these events are supported for non-VPAID <MediaFile>s as well. In addition, the following events are emitted:
      • ready: Fired when startAd() may be called and the ready property becomes true.
      • error: Fired when an error occurs with ad loading/playback.

    VASTmanka.vpaidSWFLocation:String

    The location of the SWF needed for Flash VPAID playback. The defaults to a location on the jsDelivr CDN. Only override this property if you want to use a version of the SWF you have uploaded yourself.
