createObjectURL

[shahind]

When trying to use it in a Cordova-electron app I get this error:
Uncaught (in promise) TypeError: Failed to execute 'createObjectURL' on 'URL': Overload resolution failed.
at t. (js-file-downloader.min.js:10)

(does not depend on the file type or server).

Hi @shahind , it's probably related to cordova electron.
This lib is born to support download in browser web app, the createObjectURL is part of the Web APIs.
I think you need to find a poly lib (or create it) to make this method available in your project.

Thanks @AleeeKoi. The problem is not createObjectURL. Cordova uses chromium or the internal browser, and as far as I checked, the createObjectURL is available. The problem is actually the cordova-plugin-file that seems to be overriding the native File object. This consequently affects the downloadedFile.

For any other person who faces this problem; there is no fix for this bug so far (see the related issue). To fix the problem, you need to save the window.File and window.FileReader before executing the Cordova, for example in your index.html before Cordova.js script tag (e.g. window.originalFile=window.File). You can re-assign them in the mounted function, or you may change the js-file-downloader as I did by replacing File and FileReader with originalFile and originalFileReader.(sorry @AleeeKoi :)
