Background Upload NativeScript plugin

A cross platform plugin for the NativeScript framework, that provides background upload for iOS and Android.

There is a stock NativeScript http module that can handle GET/POST requests that work with strings and JSONs. It however comes short in features when it comes to really large files.

The plugin uses NSURLSession with background session configuration for iOS; and for android - the alexbbb/android-upload-service that implements an IntentService.

Installation

tns plugin add nativescript-background-http
