[GitHub] [cordova-plugin-file-transfer] Olyster opened a new issue #328: Progress listener Total is 0 with large files

[GitBox <gi...@apache.org>]

Olyster opened a new issue #328:
URL: https://github.com/apache/cordova-plugin-file-transfer/issues/328


   # Bug Report
   
   ## Problem
   The "total" property of ProgressEvent Interface equals zero
   
   /** Events measuring progress of an underlying process, like an HTTP request (for an XMLHttpRequest, or the loading of the underlying resource of an <img>, <audio>, <video>, <style> or <link>). */
   interface ProgressEvent<T extends EventTarget = EventTarget> extends Event {
       readonly lengthComputable: boolean;
       readonly loaded: number;
       readonly target: T | null;
       readonly total: number;
   }
   
   
   ### What is expected to happen?
   total property should be equal to file size
   
   
   ### What does actually happen?
   total = 0 when downloading large file (tested with 6.6 gig file)
   loaded goes up to the file size so it's not a data type problem.
   
   ## Information
   download a large file (ex: 6 gig) and set onProgress listener
   
   
   ### Command or Code
   let currentProgress
   ft.onProgress((evt:ProgressEvent<EventTarget>)=> {
         currentProgress = (evt.loaded / **evt.total**) <-- currentProgress = "Infinity" since evt.total = 0
    })
