Progress Events

Some methods have optional onProgress callbacks to handle progress events for uploading resources.

The first argument to the onProgress callback is always a rolled up progress value from 0-1. The second will be one of the following types depending on the method.

UploadTrackProgressEvent

{
  key: 'audio' | 'image' // Which file upload triggered the event
  loaded: number // How much of the file has been uploaded, in bytes
  total: number // Total number of bytes of the file
  transcode: number // Completion percent (from 0-1) of the transcoding
}

UploadPlaylistProgressEvent

{
  key: 'image' | number // The index of the audioFile or 'image'
  loaded: number // How much of the file has been uploaded, in bytes
  total: number // Total number of bytes of the file
  transcode: number // Completion percent (from 0-1) of the transcoding
}
